I don't know how you set the original format. If you use format and style, it is very convenient to change it.First, click Format -- Format and Style. See, there is an additional box on the right. Click the body on the left, and the right will indicate the format accordingly.Click the format on the right and a drop-down selection box will appear. Then click Modify Style and a selection menu will pop up
Hehe, if you don't use the style, you have to use the stupid method on the first floor
