Call format var col = row.GetHeaderColumn( pos )
Return value If the FlexCell can be obtained successfully, the FlexCell reference is returned. If it cannot be obtained, it returns null.
Arguments integer pos Specify a column number starting from 0. For the column number, specify 0 for the first header column and 1 for the next header column. The data column is specified by the serial number in the header.
