Multiple drafts of a single document are normal, but does this mean you will have to edit the table of contents manually? No. In fact, when it comes to the table of contents in Word online, there is an option to update the table as and when there is an edit.
The updating is done, provided the headings are specified. As shown in the screenshot below.

- Once you have defined the headings and subheadings of the document, go to the table and right-click.
- You will have a dropdown menu
- Select Update Table of contents
- The new heading will now show on the table.
- This option will also be available when you hover over the table after adding new headings. Click on Update, and the new heading will be included as part of the table.
