How to Create a Table of Contents in Word 2010
You can let Word 2010 create a table of contents (TOC) for your document. You don't need to manually type a TOC. As long as you use the built-in heading styles, Word can slap down a custom TOC in your document:
Create a separate page for the TOC by pressing Ctrl +Enter to insert a page break.
You can also insert a page break by selecting the Page Break command from the Pages group on the Insert tab.
Click the mouse to place the insertion pointer on the new, blank page.
The TOC is inserted at that point.
Click the References tab and, in the Table of Contents group, click the Table of Contents button.
The Table of Contents menu appears.
Choose an item from the menu based on what you want the table of contents to look like.
Word bases the TOC on text formatted with the Heading styles in your document. As long as you use Heading 1 for main heads, Heading 2 for subheads, and Heading 3 (and so on) for lower-level heads and titles, the TOC will be spot-on.
If you need to update a TOC, click the mouse in the TOC and choose the Update Table command from the top of the TOC list.
If your document's contents change, you can change the TOC to match.
When these steps don't produce the effect you intended, it usually means that your document headings aren’t formatted with the Heading styles.
