Remove Duplicate Header Columns

LAIRPR

Hi,

I am using two grids in in my asp.net application. And one of the grids is duplicating the header.
Facility Group Submit Date Submit By Request By User Name Title Email Approved Approved Date Actions
Facility Group Submit Date Submit By Request By User Name Title Email Approved Approved Date Actions

This is how I am setting up the grids:
$(".gvv").prepend($("<thead></thead>").append($(this).find("tr:first"))).dataTable({
"lengthMenu": [[3, 5, 10, 25, -1], [3, 5, 10, 25, "All"]],
bJQueryUI: true,
sPaginationType: "full_numbers",
"bSort": false,
"bFilter": true
});
How can I remove the duplicate header?

Any help will be very appreciated.
