Tooltip in cell

Hi Aleksandra,

I tried to adopt your example to extend it in a way that I can iterate trough rows to get each row height, and then to adjust overall height of spreadsheet. However, this is not working (I am getting undefined for row height).

I my case, I have maximum number of rows set, so I know that for example, my table has 6 rows each time

Could you check it?
