The Excel setting is Dark Gray, and it turns out to be super black inexplicably when opened today, and there are some dotted lines in the table.
I checked online and there are several methods, but none of them worked.
Open the print preview -> Excel 2019 I can't find where to turn off this thing (but I didn't get ctrl + p, and this problem will occur when I create a new table)
The page break is displayed -> this can be turned off, but only the dotted line is not displayed (what I want is to restore the dark gray)
Word and PowerPoint are not affected. Does anyone know why?
The blackened Excel UI seems a little different from the black Office Theme.
