In my proejct i wanted to add rows and i did it as shown below. Get the handle of the table and existing data. Then if you want to add new columns then please change the column numbers to be added. Then set new data to to table.

 caOldData = get(hTHandle,'Data');
 caNewData = [caOldData; cell(nRows, nColumntoAdd)];
 set(hTHandle, 'Data', caNewData);
