When I download certain auto generated reports, or convert a pdf to excel, I end up with no gridlines. The usual tricks to get them back don't work. In the View tab 'Gridlines' is checked. The color of the lines is set to automatic, and changing them manually to gray doesn't get them back. The only way I get get them back is to use the boarders tool and select All Borders. But that gets me the heavy black lines, and I want the regular light gray lines. I find it hard to work without gridlines at all, or with the heavy ones. Aside from saving as a csv and re-opening, does anyone know how to get the regular ones back?
