1. Stay at the end of the directory and insert the separator: tab page layout → separator → section break next page.
2. Place the cursor on the first page to be numbered and edit the footer. On the Header and Footer tool tab, by default, linking to the previous header is enabled, and it will be disabled after clicking, so that you can set a footer different from the previous content, such as customizing to insert pages and titles with different formats.
3. Insert the page number in the required page and set the page number format → at least the page number is 1.
4. If the page number has been inserted in the cover and table of contents before, you can delete the page number of the previous page directly after the above operation.
