OK, I present an updated version of the really rather good already EditableTable1.1.
Feed it any table you like, preferably a wide one, & then use the scroll bar to move to the right. Click a cell & see if you can spot the textbox (you could make the form wider if you can't see it at all). Also try activating the textbox & then moving the scroll bar.
I've got a way to go to get this right...
