I feel like a dunce, but I can't figure out what I'm overlooking. I have a spreadsheet that I'm trying to clean up by deleting some rows. When I press the button for this, the choices to add rows/columns are highlighted, but the ones to delete rows/columns are grayed out. Selecting the row to be deleted does not change this. This has to be simple. What am I missing?Thanks.

I finally was able to delete the rows. Instead of selecting a row to be deleted by highlighting the cells themselves, I needed to highlight the row number, which then highlights that row.Simple and straightforward. No wonder I missed it.

Good to know. Numbers does it the same way, though it's an gray bar next to the table you select.
