Assigns Value to Cells[Row, Col].BestWidth, as an editing operation.
procedure SetCellBestWidth(Value: Integer; Row,Col: Integer);
Unlike a direct assignment to Cells[Row, Col].BestWidth property, this method can be undone/redone, if it was called for table inserted in TRichViewEdit (after insertion).
Use this method in conjunction with methods for updating editor window, see example.
