It’s a good idea to include a table of contents in your long documents. And better still, to format it to include tab leaders. So read on to find out how to insert tab leaders in a table of contents. I’ll show you how to add them to an automatic table of contents (always the better option). And also show you how to add them to a table of contents you’ve typed into your document.

What are tab leaders?

Microsoft Word’s tab leaders line up information.

That is, they provide a visual connection between information. And as such, help a reader to connect an item with its corresponding information.

While tab leaders are more commonly used in a table of contents, they can be used in lists. For example, to link a price to an item.

Word has three different tab leader options to choose from (apart from no tab leader).

Two reasons come to mind as to why your table of contents doesn’t already include tab leaders.

The first is the most likely one. And that is that you’ve added a table of contents by typing in each heading and its corresponding page number.

The second is that the document you’re working on has an automatic table of contents. But the table of contents has been formatted to not include tab leaders.
