              Select one of the following: - 
                  Update page numbers only   This only updates the pages that the headings are on, and ignores any changes to the heading text. 
- 
                  Update entire table   This will reflect any updates to the heading text, as well as any page changes.

              Select OK. 
Note:Â Manually created tables (not created automatically from the headings), can't be updated by Word. You'll need to manually type your changes in the table of contents.
