Use "format >; > style and format "edit the subtitle in the article, stop the cursor in the directory you want to generate, and then click" new style "that appears on the right. Different formats (including font and font size) can be selected for different levels of titles in the pop-up dialog box. After modifying all the header formats, click Insert in the toolbar-> Quote-> Indexes and directories

The above is my own summary, or look at the following:

1) Modify the format of the heading style. Usually, the title style of word does not meet the requirements of the paper format and needs to be modified manually. Click the menu bar? Format | Style? , select from the drop-down list? All styles? , click the appropriate heading style, and then click? Change? . Modifiable contents include font, paragraph, tab stop, number, etc. The format of the title 1-3 is modified according to the requirements of the paper format.

2) Apply the corresponding format to the title paragraph of each chapter. What is the chapter title used? Title 1？ Style, chapter title use? Title two? , the third grade title is used? Title 3? . Another advantage of using styles to format titles is that it is very convenient to change the title format. If you want to change the font size of all the first-level titles to small three, change it directly? Title 1？ The format of the style is updated automatically after it is set, and the title font size of all chapters is changed to small three, which is very troublesome and prone to mistakes without manual modification. For information about how to apply styles and automatically update styles, see word Help.

3) Extract the directory. According to the requirements of the article format, the table of contents is placed in front of the text. Insert a new page before the text (insert a page break before the title of the first chapter), move the cursor to the beginning of the new page, and add? Directory? Word, and set the format. To start a new paragraph, select? Insert | Index and Table of Contents? , point? Directory? Tab，？ Display level? For level 3, others don't need to be changed. After confirmation, word will automatically generate the table of contents. If a chapter title is not in the directory, it must be that the title style is not used or used improperly, and there is something wrong with the directory generation, not word. Please go to the corresponding chapter to check. After that, if the chapter title changes or the page number changes, just update the table of contents.

Note: After the table of contents is generated, sometimes the table of contents text will have gray shading, which is the field shading of word and will not be printed when printing. Are you online? Tools | Options? what's up Opinion? This tab can be used to set the display mode of field shadows.
