How can we exclude particular column or set of columns (for example: View, edit, delete buttons in the action column) from Datatable during export to pdf or excel?
how can i do that?
snippet form my datatable:

$('.example').dataTable({ "sDom": 'T<"clear">lfrtip', "oTableTools": { "sSwfPath": "<?php echo base_url()."js/jtable/";?>copy_csv_xls_pdf.swf" }, "aaSorting": [[ 5, "desc" ]], "iDisplayLength": 10, "aoColumnDefs": [ { "bSortable": false, "aTargets": [ 8 ] } ] });
