Hi,
i am facing problem of column and header width are not matching. we have used fixed header function. so is there any problem of that.
Below is my code in that


$('td:eq(' + labno + ')', nRow).html('' + aData[labno] + '');





var oTable = $('#example').dataTable({
"sDom": 'R<"H"lfr>t<"F"ip>',
"bJQueryUI": true,
"sPaginationType": "full_numbers",
"iDisplayLength": parseInt(PerPageCount),
"bFilter": true,
"bAutoWidth": false,
"aLengthMenu": [[10, 20, 50, 100, 250], [10, 20, 50, 100, 250]],
"fnRowCallback": function (nRow, aData, iDisplayIndex) {
var oTable;
var oTable = $('#example').dataTable();
var oSettings = oTable.fnSettings(); // you can find all sorts of goodies in the Settings
var TotalColumns = aData.length;
var labno;
var PacketNo;
var STONE_STATUS;
var IS_NEW;


var ColumnCount = $('#Table1 >thead >tr >th').length; //Get Number Of Column in Grid

//original table #example
$('#Table1 >thead >tr >th').each(function (index) {
if ($(this).text() == "Lab") {
labno = index;
}
if ($(this).text() == "Packet No") {
PacketNo = index;
}
if ($(this).text() == "STONE_STATUS") {
STONE_STATUS = index;
}
if ($(this).text() == "IS_NEW") {
IS_NEW = index;
}
if ($(this).text() == "CERTI_LINK") {
CERTI_LINK = index;
}
if ($(this).text() == "Cart") {
CHK_CART = index;
}
if ($(this).text() == "Watch") {
CHK_WATCH = index;
}
if ($(this).text() == "Office") {
CHK_OFFICE = index;
}
if ($(this).text() == "Order") {
CHK_ORDER = index;
}
if ($(this).text() == "Select") {
CHK_SELECT = index;
}
if ($(this).text() == "Diamond DNA") {
REAL_IMAGE = index;
// alert("index" + REAL_IMAGE);
// alert("with data" + aData[REAL_IMAGE]);
}
if ($(this).text() == "DIAGRAM_IMAGE") {
DIAGRAM_IMAGE = index;
}
if ($(this).text() == "HEART_IMAGE") {
HEART_IMAGE = index;
}
if ($(this).text() == "ARROW_IMAGE") {
ARROW_IMAGE = index;
}
if ($(this).text() == "ASST_SCOPE_IMAGE") {
ASST_SCOPE_IMAGE = index;
}
if ($(this).text() == "CERTI_IMAGE") {
CERTI_IMAGE = index;
}
if ($(this).text() == "VIDEO_PATH") {
VIDEO_PATH = index;
}
});

oTable.fnSetColumnVis(STONE_STATUS, false);
oTable.fnSetColumnVis(IS_NEW, false);
oTable.fnSetColumnVis(CERTI_LINK, false);

oTable.fnSetColumnVis(DIAGRAM_IMAGE, false);
oTable.fnSetColumnVis(HEART_IMAGE, false);
oTable.fnSetColumnVis(ARROW_IMAGE, false);
oTable.fnSetColumnVis(ASST_SCOPE_IMAGE, false);
oTable.fnSetColumnVis(CERTI_IMAGE, false);
oTable.fnSetColumnVis(VIDEO_PATH, false);

if (aData[1] == "select") {
// alert("check");
$('td:eq(1)', nRow).html('');
$('td:eq(1)', nRow).removeClass("Expand");
//
}


$('td:eq(' + labno + ')', nRow).html('' + aData[labno] + '');
$('td:eq(' + labno + ')', nRow).removeClass("Expand");
return nRow;

}

});

$('input[type=checkbox]').click(function (event) { event.stopPropagation() });
var oFH = new FixedHeader(oTable);
