Answer 1

I have updated the apache-poi from 3.14 to 4.1.0, where 4.1.x version provides the method addColLabel(columnIndex). Using addColLabel(columnIndex) allows to select particular column as column fields for the pivot table creation.

Code:

            pivotTable.addReportFilter( 12 );
            pivotTable.addReportFilter( 13 );
            pivotTable.addRowLabel( 11 );
            pivotTable.addColLabel( 0 );
            pivotTable.addColumnLabel( DataConsolidateFunction.SUM, 15 );
