    IMPORTANT:
    Strictly adhere to the following sequence when creating a pivot table:

    pPivot->SetColFields(aColArr, aColCount)
    pPivot->SetRowFields(aRowArr, aRowCount)
    pPivot->SetDataFields(aDataArr, aDataCount)
    if (pPivot->CreateData())
    {
        pPivotDrawData();
        pPivotReleaseData();
    }

    Make sure that either ColArr or RowArr contains a PivotDataField entry.
