Why can't I add rows near the bottom of my table in numbers?
I have a simple table in Numbers which I've been using for about a year. I can no longer 'add row below' near the bottom of my table. I can still add rows up higher in the table, just not near the bottom. I do have a footer row that sums up some things. I don't have any filter turned on. I've been adding a row above where I want it, then moving lines up by cutting and pasting to create a new row at the bottom where I want it. I'm tired of this workaround and have not been able to find a solution. Any ideas?
