UpdateTableShape() is called when we call SetAttrToSelectedCells method

IMO Calling this method again is not required. The If Blocks returns
false when User Clicks "Cancel" Button in "Format Cell" Widget,
IMO on Cancel Their is no need to Update the table. And on Ok
SetAttrToSelectedCells method is called which inturn calls
UpdateTableShape() method.
