To make an automatic table of contents in Word, apply Heading 1 to main sections and Heading 2 or Heading 3 to subsections. Place the cursor where the contents should appear, then choose References, Table of Contents and an automatic style. Word uses the headings to build the entries and page references.
After editing the document, select the table and use Update Table. Choose Update entire table if you changed any headings, added or removed sections, or changed their order. Updating page numbers only is useful when the entries are already correct and only their page positions moved. Check the finished contents against the document before submitting.
- Use real Word heading styles for the sections that should appear.
- Insert an automatic table from the References tab.
- Update the entire table after changing headings or their order.
- Fix a missing entry at its source heading and update again.
- Check the final page numbers and links in the delivered Word or PDF copy.
Decide what the contents page needs to show
Start by looking at the document as a reader. A contents page can show main sections only or include a second and third level. A short school report may need only Introduction, Method, Results and Conclusion. A longer report can benefit from subsections that help a reader find an experiment, table discussion or appendix. Use the teacher’s instructions if a depth or structure is specified.
Main headings and subheadings have different jobs
A main heading identifies a large part of the document. A subheading divides that part into smaller topics. If “Method” is a main heading, “Materials” and “Procedure” might be subheadings inside it. Using Heading 1 for all three would put them at the same level in the contents. Apply the levels that match the actual relationships.
A third level is useful when a subsection contains several distinct topics, and it can make a short table crowded. For example, “Procedure” might contain “First trial” and “Second trial.” You can format them as Heading 3 for navigation while configuring the visible contents to show only two levels, where the desktop customization supports that. This keeps the document structured without requiring the front page to list every small heading.
Keep document titles separate when appropriate
A report’s cover title, a label such as “Contents” and an introductory heading can look similarly large. Decide which belong in the contents. If the title is a cover label rather than a section, use an appropriate title or ordinary styled paragraph instead of assigning it a heading level just to make it look big. Check that your template does not already include a contents heading designed for this purpose.

Apply Heading 1, Heading 2 and Heading 3
Select the actual heading paragraph. In Word, use the Styles controls on Home to apply the appropriate built-in heading style. Repeat for each heading that should appear. Formatting text with bold or a larger size can make it look like a heading while leaving it as a normal paragraph. An automatic table needs the document’s heading structure or another configured source, not visual appearance alone.
Style the entire heading paragraph
Place the cursor in the heading paragraph and apply the intended style. Check that the text on the next line belongs to a different paragraph if it should be body text. If a heading and its following sentence are in the same paragraph, the whole paragraph can appear in the table. Separate them at the source and assign an appropriate body style to the explanation.
Use a simple outline before inserting the table
A science report might have four main headings: Introduction, Method, Results and Conclusion. Method can contain Equipment and Procedure. Results can contain Data and Observations. Apply Heading 1 to the four main headings and Heading 2 to their subsections. Open Word’s Navigation Pane where available and inspect the outline. If “Data” is beside “Results” rather than nested under it, fix the heading level before creating the table.
Keep visual style and structure together
If Heading 1 looks different from the required format, modify the style or use the approved template. Avoid replacing the style with ordinary bold text just to adjust its appearance. Where your version allows it, a style change can update all headings of that level consistently. Check the actual document and the visible contents after changes to styles.

Insert an automatic table of contents
Place the cursor where the table should go. For many reports this is after the cover and before the introduction, but use the order requested by the assignment. In Word, open References, Table of Contents and choose an automatic option. Microsoft documents this heading-based workflow across supported Word versions. The exact menus and customization options vary by platform.
Choose an automatic table when the report will change
An automatic table is built from the headings and can be updated. A manual table gives you placeholder entries to type yourself. That can suit a special layout that is intentionally maintained by hand, but the entries and page numbers do not follow later edits automatically. If you expect to add pages or rename sections, use an automatic table unless the brief requires another approach.
Place it in its own page area if required
If the contents needs to start on a fresh page, use a proper page break or the appropriate section setup. Repeated blank lines can move unexpectedly when the table grows. Check the layout after insertion. A table with several levels may extend onto a second page. Decide whether that is allowed, or adjust the displayed depth if the reader does not need every subsection.
Check the first and last entry immediately
Open the table and find the first main heading and the last required appendix or conclusion. Verify their order. If a heading is missing, fix the heading paragraph rather than typing directly into the generated entry. If an unwanted label appears, inspect its style and why it was included. Update the table again after the source correction.

Update page numbers or update the whole table
Use the Update Table action for an automatic table. Depending on the interface, it can be available above the selected table or through References. If Word asks which part to update, choose the scope that fits the edits. Updating page numbers only leaves the existing entry text and structure in place. Updating the entire table refreshes the entries along with their page references.
Use a page-number update after a layout-only edit
Suppose you add a photograph on the second page and it pushes the Results section one page later. The headings themselves did not change. Updating page numbers can refresh the table. Check that the first shifted entry and any appendix now show the correct labels. If the edit also added a heading, update the entire table instead.
Use a full update after changing the structure
If you rename “Materials” to “Equipment,” move a section or add “Limitations,” choose a full update. Look for the new heading and verify that any removed entry is gone. Check the indentation and page reference. A table can show accurate page numbers next to outdated wording if you use the page-number-only option after renaming a section.
Recheck after the final correction
An edit to one paragraph can move an entire page break. Update the contents near the end of the document workflow, after the layout has settled. Save and reopen the file. If a later correction affects the layout, repeat the update and verify the exported version. An earlier PDF will not change when the Word table is updated.

Fix missing, extra or incorrect entries
Start at the heading in the document. Open its paragraph style and check its level. If the entry is missing, a visual heading may have been made with bold alone. Apply the correct style. If a heading is at a deeper level than the table displays, decide whether to include that level or adjust the document’s structure. Update the table after the change.
A body paragraph appears in the contents
Check whether the paragraph accidentally has a heading style. Change it to the appropriate body style, and verify the neighbouring heading. If the heading line and body text share one paragraph, separate them first. The table should list the section name, not several lines of its explanation.
A heading appears at the wrong level
A subsection can be styled as Heading 1 by mistake. Compare it with the document outline. Apply Heading 2 or Heading 3 where appropriate and update the table. Do not move a heading to a different semantic level purely to obtain a particular indentation. Use formatting controls for appearance and heading levels for structure.
A renamed heading still shows its old words
Update the entire table. If the old words remain, check whether the document uses a manual table or has more than one contents table. Verify that you selected the intended one and that the new wording is in the actual heading paragraph. If the table was manually edited, an update can replace those edits with the source heading text.

Customize levels and appearance in desktop Word
If the default layout does not match the assignment, look for the Custom Table of Contents option in supported desktop Word. Microsoft documents controls for how many levels are shown, page number alignment, tab leaders and appearance. Use the options the recipient requires. Keep a copy before changing a complex template.
Show only the levels the reader needs
A long report can use Heading 3 in the body and display only Heading 1 and Heading 2 in the table. This gives the reader an overview without adding every small topic. Preview the new table and check that critical sections are still visible. If a required appendix is missing, inspect the style or configured level before changing the display depth.
Check dots, page numbers and alignment
The dotted leader helps the reader track from a title to a page label. Use it if the brief or template calls for it. If the table wraps a long heading onto another line, inspect the alignment. A short, accurate heading may be clearer than squeezing a long title into one line. Keep the exact wording where the assignment requires it.
Modify the table’s styles instead of editing its generated words
An automatic table can replace direct edits during an update. If you want different indentation, size or spacing, use the supported table styling controls where available. Keep a consistent look for entries at the same level. After updating, inspect a first-level and second-level entry to confirm the formatting stayed as intended.

Check page numbering when the report has front matter
A contents page can be the second physical page while the introduction shows printed page 1. This is common when cover and front matter use different numbering. Word can use sections with different page-number formats or starting values. Check the recipient’s requirements before changing them. The contents should point readers to the visible page labels the document uses.
Compare the entry with the page footer
If “Introduction” shows page 1 in the contents, open its page and verify the printed label. The PDF viewer may show that physical page as page 3. Both can be correct if the document uses separate numbering. If the visible footer disagrees with the table, check the page-number settings and update the full table.
Watch for a layout change near the contents page
A table can become longer when a new subsection is added. That can move the introduction to another physical page. Check section breaks, margins and the table’s final length before updating. A correct page label is useful only if the document’s structure is also correct.
Check appendices separately
If an appendix uses a different numbering scheme, verify the first and last relevant entries. A table of contents, list of figures and list of tables can serve different purposes. Follow the brief for which lists are required and where they belong. Do not assume the contents table includes every figure caption automatically.

Verify the table in Word and in the exported PDF
Open the saved Word file and select an entry using the link behaviour appropriate to your version. Check that it goes to the intended heading. Compare the visible page label with the table entry. Repeat for a middle section and the final appendix. If the recipient will use a PDF, export from the updated Word document and test the relevant links there.
Verify the file the reader will receive
A PDF may show the right headings but lose clickable links depending on how it was made. Use the export route that preserves the features your brief requires, and test the saved result. If the recipient needs only a printed copy, check the page numbers and readability instead. Keep the DOCX as the editable source for future changes.
Check the contents after exporting another revision
If a teacher requests a correction, make it in Word, update the table and create a fresh export. Open the revised file and verify the changed heading or page. Use a clear working label or distinct folder when the delivered filename has to stay the same. Follow the recipient’s replacement procedure if the old PDF was already submitted.

Build a contents page for a report with front matter
Consider a report with a cover, a short declaration, an introduction, a method, results and two appendices. Read the template and identify which front-matter items should appear. A cover can stay outside the visible table while the declaration appears as an entry if required. Give the main sections the correct heading levels and format other labels separately. Insert the automatic table at the required position.
Work out what happens when the contents grows
Suppose the table originally occupies one page. Adding two subsections makes it longer, and the introduction moves forward by a page. If the document uses a section break before the body, the first visible body page can still display 1. Check that the introduction’s physical location still meets the brief. Update the entire table and compare the printed page label with the entry.
Use headings that make sense without the previous paragraph
A contents entry such as “Other points” gives the reader little help. When the brief allows you to choose the wording, use headings that describe the section, such as “Limits of the survey” or “Follow-up interviews.” Keep headings concise and meaningful. If a template requires exact labels, use those labels and let the hierarchy provide context. A good contents page helps a reader choose where to go next.
Check a report that includes a separately numbered appendix
The appendix may continue the main numbering or restart with another format. The contents should match whatever the document is required to show. Check the first appendix heading and its visible page label. If the final export combines separately created files, inspect the complete PDF and verify the actual page labels and links. An update in the original Word file cannot change a later merge on its own.

Repair heading problems in a document copied from another file
Copied material can bring styles, list numbering or manual formatting from the source. After pasting, inspect the headings in the destination document. A copied subsection may use Heading 1 where your report expects Heading 2. A paragraph that looks like a heading may use a custom style that the table does not include. Apply the correct structure in the destination and update the table.
Check custom styles before changing a template
Some templates use specially named styles for chapters or appendices. Supported desktop Word can allow a custom table to map styles to contents levels. If the institution supplies that mapping, keep it. If a new style needs to appear, configure it through the supported options or apply the approved heading style to the paragraph. Verify both the outline and the displayed entries after changing anything.
A multi-line heading brings in extra text
If the heading wraps naturally because it is long, the whole heading should appear as one entry. If it includes a soft line break or the start of a body paragraph, check whether the text is intentionally part of the heading. Separate the body text at the source and update. The generated entry should reflect the document’s title for that section, without an explanation that belongs in the body.
A heading appears twice
Find both source headings. A duplicate can be legitimate if two chapters each have a subsection with the same name. The indentation and surrounding chapter entries should make the difference clear. If one is unintended, inspect whether a copied placeholder, title or hidden-looking paragraph received a heading style. Correct the source and update the full table. Avoid deleting only one generated line, since an update can bring it back.

Decide what belongs in the contents and what belongs in a separate list
A table of contents normally helps a reader navigate the document’s sections. A list of figures can help locate charts and pictures, and a list of tables can identify tabular material. The assignment can require all three or just one. Check the instructions before trying to put every title and caption into the main contents page.
A figure caption is missing from the contents
If the report uses a separate list of figures, use the caption and list workflow required by the template. Keep the figure caption at its source and check that it appears in the correct list. Giving every caption a main heading style can crowd the contents and distort the document’s structure. Use the appropriate mechanism for the list the reader needs.
An appendix has several parts
An appendix can have its own title and individual subheadings. If the reader needs to find each part, show them at the appropriate level. If the contents only needs to list the appendix as one entry, keep its subheadings in the body outline and use the table settings to limit display depth. Verify the result against the actual requirements.
A cover title is accidentally included
Open the cover title’s paragraph and inspect its style. Change it to the approved title style or other appropriate format when it should not appear in the contents. Update and check the first real section. If the cover deliberately belongs in the navigation structure, follow the template’s instructions rather than removing it automatically.

Make a long contents table easy to scan
Start with the document’s hierarchy. Indentation should show what belongs under each main section. Page labels should align consistently when the style requires it. Check long headings and wrapped lines. Use the template’s typography and spacing. For a short report, two levels often give enough detail, but the assignment determines the right amount.
Review a two-page contents table
If a full table spans two pages, inspect the break between them. Make sure the reader can tell which main section a subsection belongs to. Check whether the template expects a title on the second contents page or permits a single continuous table. If the document has a fixed page limit, consider whether fewer displayed levels are acceptable. Verify the entire table after changing the layout.
Test page references that use Roman numerals
Suppose the declaration is labelled ii and the body begins at 1. Check one front-matter entry and one body entry. The labels should match the actual pages, even though the physical page count is different. If a label is wrong, correct the numbering settings and update the table. A manually typed correction in the table can be lost later.
Review the links in the intended format
In Word, test a link from the top, middle and end of the contents. In a PDF, test the corresponding links if the brief requires them. A link can navigate to the correct heading while the visible page label needs updating. Check both. If the output is meant to be printed, confirm that the page labels remain readable without links.

Keep the contents current when several people edit the report
Assign one person or workflow to prepare the final document. Ask editors to use the approved heading styles as they add sections. A person pasting material from another file should check the destination styles. Before delivery, review the complete outline and the automatic table together. This avoids relying on a table that was created before the latest changes.
Two team members added headings at the same level
One added “Results,” and another added “First trial” as a main heading. Inspect the outline and identify the correct relationship. Move or restyle the heading if it belongs inside Results. Update the table and check the indentation. Then read the body headings in sequence to confirm the outline serves the reader.
A correction changes the report title and adds a section
Correct the title where it appears, add the section with the proper heading level and update the entire table. Check that the cover label still stays outside the contents if that is intended. Export again and open the actual PDF. Verify the new section, first body page and final appendix before submitting the replacement.
Keep the editable source with the approved result
Retain the DOCX and the accepted output where the process allows. If the final PDF is later replaced, the updated table in Word is the starting point for the new export. Use a distinct location or working name so the older PDF is not uploaded accidentally. Check the table in the file that was actually accepted.

Practise on a short report before a deadline
Create a test document with a cover, a contents page, two main headings and two subsections. Apply Heading 1 and Heading 2 and insert an automatic table. Rename one subsection and add a paragraph above a different heading. Update page numbers only and notice that the old entry wording can remain. Then update the entire table and verify both the new wording and page references.
Break one heading deliberately in the test copy
Change one heading to body text but keep it visually bold. Update the table and see what happens to the entry. Apply the proper style again and update. The exercise shows why looking at bold text alone cannot diagnose a missing entry. Apply the same check to any heading that does not appear in a real report.
Check the table after an export
Save the test as PDF using your intended workflow. Open it and compare the first and last entries. If clickable links are required, test them. If the visual labels differ from the viewer’s position numbers, identify which number belongs to the document’s printed scheme. Verify both Word and PDF before closing the task.

Check an automatic contents table after a document is combined
If you assemble several sections into one Word document, apply the destination document’s heading rules before updating its contents. A heading can keep a copied style that looks right but belongs to the wrong level. Review the first heading from each source, then update the entire table and check their order. If you merge exported PDFs instead, remember that the old Word table will not recalculate the merged file’s new physical positions. Prepare the contents and check the final PDF in the workflow the brief permits.
Test the handoff with one real navigation task
Ask the intended reader or a teammate to locate a particular subsection from the saved file. Check that its name, indentation and page label let them find it. If a digital link is required, confirm it lands at the correct heading. Make any change in the editable source, update the table and export a new verified copy.
