unable to select a cell in a table in smartforms

Hello experts,

I have to apply border to a particular cell in the table in a smartform. Iam unable to select the cell in the table, while I am able to select the same in a template. Could you please help me with this on how to be able to select a prticular cell in table row. Do we have to do any settings? Please help me with this. (the table has all its rows placed inside a folder i.e., TABLE>FOLDER>ROWS ). Further I am able to see a PATTERN box which we normally wouldnt see when we insert a table command in table.

Thanks and regards,

Aditya
