First, open the Word document, place the cursor on the first page, and click Insert-Blank Page. Then click Reference-Content-Smart Content. Because we have a first-level title, a second-level title and a third-level title, we choose to insert the third directory. Click on the table of contents, and you can use intelligent AI technology to insert the table of contents in the paper. If the title changes, how to update the table of contents? For example, if we change the title to "Chen Xunqi the Almighty Genius" and click "Quote-Update Catalog", we can intelligently update the catalog. If we don't want to generate the catalog automatically, what about customizing the catalog? For example, the job description is set as a first-level title and the preface is set as a second-level title. Select the title of the directory to be generated, click Reference-Directory Level, and select the required level. Click Reference-Directory-Automatic Directory to customize the directory setting.
