Thanks for contacting us! If I’m understanding you correctly then yes, this is possible. With Ribbet’s new collage functionality you can move the borders of cells to position them exactly how you want them. To do this simply hover over the border between 2 cells and then drag the border to reposition it.
You could also leave a blank cell if that helps achieve what you want.
If I’m misunderstanding you and this isn’t helpful then please let us know and we’ll try to help as far as possible. Thanks!
