First, the format of various titles.
Change the format, select Format-Style and Format, and a style and format sub-box will appear on the right. If your format is already in a mess.
Then I suggest you choose "New Style" and enter your own new format theme in the pop-up dialog box, preferably different from your messy format. For example, "My title 1" and "My title 2". Remember, there need to be two spaces between the title serial number and the title. Manual input.
Secondly, generate a directory.
You can automatically generate the table of contents in insert-reference-index and table of contents (provided that your title has been changed correctly). Select your table of contents, right-click paragraph-set line spacing-fixed value and change it to 20 points.
Third, about the header.
As far as we know (there may be mistakes, but it's almost the same), we don't need to display headers on the cover, abstract and table of contents, but if we add headers to the text, do all of them have headers? It is too much trouble to print separately. Here's how to do it.
1, open the paper
2. Don't set the header in a hurry at this time, but position the cursor at each position where a new header is needed, and then execute the Insert Menu → Delimiter command. Select the "Next Page" check box in "section break Type" and click the "OK" button, taking this as an example to process the whole document in sections.
3. After the whole article is divided into chapters, you can click View menu → Header and Footer to enter the header editing mode. If the title is entered as required. But at this time, the article in front of the text still has a title. Did you notice the word "same as the previous section" on the title on the right?
At this point, you should click the "Link to the previous section" button in the header and footer toolbar to cut off the connection between the three sections and the header content of the previous section. Then just delete the text in the title of "Content" in the previous section. Other operations and so on.
