1. Before using WPS to generate the table of contents, unify the format of the title and subtitle in the text. As shown in the figure, multiple classifications should use the same level of titles.

2. After unification, insert a blank page on the first page of the document, and then click Reference-Contents.

3. Then there are several forms to choose from in this catalog, or you can set the style of the catalog.

4. This is the style of the table of contents, and the page, alignment and dotted line style can be customized.

5. After setting and inserting the directory, a directory will be automatically generated according to the contents of documents on this page. If there are subheadings at other levels in the table of contents, they will also be displayed.
