How do I add gridlines to certain cells in a Numbers spreadsheet on my Mac?
Clicking on the Gridlines symbols in the sidebar in Numbers doesn't work. I somehow lost the horizontal and vertical gridlines in some cells on an old Numbers spreadsheet and would like to put them back. I'm using Sequoia 15.3.1 on an M4 Mac
It's such a simple question that there is very little info about it other than "click the gridlines in the sidebar." Except that doing that isn't working.
