For example, use Heading 1 for main headings, Heading 2 for subheadings, and so on. Once you've finished creating headings, follow these steps to insert a table of contents into your Word document.

You can add a table of contents in Word to make your document look more professional and well-developed.

It's easy to add page numbers, headers, footers, title pages and a table of contents to your Word documents. You just have to know where to look.

When you insert the table of contents, Word uses all text styled with one of the built-in heading styles. In this case, we kept things simple and used only one heading level, Heading 1.
