You can add a table of contents to the document. To successfully add a table of contents, you should correctly take a style with a level, such as the Heading 1 ~ Heading 9 style. Although there are other ways to add a table of contents, it is most convenient to use a band-level style.
Navigate to the location where you want to insert the table of Contents, select Insert | reference | Index and Table of Contents command from the menu, display the index and Table of Contents dialog box, and click the Contents tab, as shown in Figure 24.
In show level, you can specify several levels in the TOC to determine how much the directory is to be refined. These levels are from the Heading 1 ~ Heading 9 style, and they correspond to the level 1~9 respectively.
If you want to set a more elegant TOC format, you can select a different type in format. The default "from template" is usually used.
Click the OK button to insert the table of contents. The directory is inserted into the document as a "domain" (gray shading appears), so you can update it.
When the content or page number in the document changes, right-click anywhere in the table of contents, select Update field, and display the Update Catalog dialog box, as shown in Figure 25. If only the page number changes, select Update page numbers only. If there are any changes or additions to the title content, you can choose "Update entire Catalog".
