Table of Contents - Word
The Automatic (Easy) Way:
Type a Heading on its own line in front of each part of the document you want in your Table of Contents. Click on each heading, then click "Heading 1" under the "Home" tab. Use "Heading 2," or "Heading 3", for sub-sections, or sub-sections within sub-sections. Then click where you want your table of Contents to be, and click "Table of Contents" under the "References" tab. Choose one of the automatic tables.
- Note: If you change the document, be sure to click "Update Table" under the "References" tab.
