If you're using the new editor, click a cell and a little blue bar will appear on the left side - click that. If you're using the classic editor, just right-click on the table. (Honestly, the classic editor makes way more sense to me).

If you're on a tablet, I'm not really sure. You may have to experiment, but it's probably similar to how the new editor works.
