The table of contents is a neat little box the shows up on the right hand side of the page content, that gives some internal links to sections in a page.

Table of contents example:

The table of contents works by using headers (H1 H2 H3) to make anchor points in the page. 

Possible reasons Table of Contents not showing

  1. There are no headers on the page. Sometimes people accidentally use Bold instead of a header. 
  2. Screen width is too small. If the screen width is too narrow (like on a mobile device) the table of contents will be hidden.
