Setting method: 1. Click the button shown in the figure at the lower right corner of the page layout tab; 2. In the pop-up page setting dialog box, select the document grid tab, and select the No Grid option, as shown in the figure.
It seems that the header and footer cannot be deleted, but I just found a way to make it not affect the body. My word is Word 2003, you can also try it.Open the file==>Page setting==>Layout, and lower the height in the header and footer. After I adjust them to 0.05, they will run up and down. They will no longer affect the format of my body. You can try it, hoping to help you.
