I have a pivot table whose data header is not visible. I tried the following..It does'nt work.
'headerMap' => array(
'org_unit_name'=>'Org Unit',
'kpi_name'=>'Kpi Name',
'active_status'=>'Active Status',
'user_coord_name'=>'Coordinator Name',
'id'=>'Sequence',
'excecption_short_en'=>'Exception',
'excecption_short_ar'=>'Exception_ar',
),
'showDataHeaders'=>true,
