Every time I graduate, many students are faced with a problem, that is, the writing method of graduation theory is to copy and paste chapter by chapter and make a catalogue. I hope it will help you: 1. Set the title format to 1. Select all the first-level titles in the article; 2. At the left end of the Format toolbar, click "Title 1" in the Style list. 3. According to steps 1 and 2, set the second-level and third-level header formats as Heading 2 and Heading 3. 2. Automatically generate the directory 1. Position the cursor to the left of the first line of the article on page 1 (the table of contents should be in front of the article); 2. Execute the menu command "Insert/Reference/Index and Directory" to open the "Index Directory" dialog box; 3. Click the Directory tab in the dialog box to make relevant settings, click OK to position the cursor at the end of the directory page, perform the operation of Insert/Delimiter/Next Page/OK, and insert a page break between the directory and the text; Execute the View/Header and Footer command, position the cursor at the footer of the first page of the text, and click the Link to Previous Page button on the Header and Footer toolbar to link the footer of the text with the footer of the table of contents. Execute the Insert/Page Number command, select the page number format in Format, select the starting page number as 1, and click OK. At this point, the page number of the text is inserted. If the directory is multi-page, you can choose a page number format different from the original page number when inserting the page number.
