Adding a table of contents to your document can actually be pretty easy, as long as you have the proper formatting in your documents. Once the formatting is set-up, inserting a table of contents into your Word 2010 documents takes just a few clicks.
You can format your document two different ways. The most common way is to use styles, such as Heading 1, Heading 2, and Heading 3, and Heading 4. Microsoft Word will automatically pick of these styles and add them to your table of contents. You can also use outline levels in the body of your document. This is a bit more complicated and you run the risk of messing up your formatting unless you have a strong understanding of Word outline levels.
Once you have the formatting applied to your document, you can add a pre-formatted table of contents with 3 clicks of your mouse, or you can insert a table of contents manually by typing each item.
