I was able to test this on GB trunk, although I’m not sure what the intended behavior should be. The Edit Table menu actions are all relative to the currently selected row (eg Insert before, Insert after). After deleting a row, no row is selected anymore and the menu options are all grayed out until you click back into a row. This happens regardless of how many rows are left in the table.

That being said, if you’ve deleted the last body row of a Table, you can only click into the Header row, so you can only add more Header rows. So if you’ve deleted all the body rows from a Table, it does not seem possible to add any body rows back without starting over entirely.

I'm curious about this issue.I tried testing it and it looked like this.

When I tried to insert the body line again, I was able to insert it. However, if it was outside the frame, when I tried to insert it, it was grayed out and I could not insert it.

outside the frame
