You would need to rerun whatever code you have attaching them at the moment. If you are referring to the DataTables event listeners, then you will need to disassemble DataTables almost entirely. It just wasn't designed to do what you are looking for there. Allan

Thank you!

Yes Allan, it works, for my case. :-) The warning no longer pops up after I implemented it.

I'm having the same exact issue. What gives?

my code for data table is $(document).ready(function(){ var t = $('#contractList').dataTable( { "sDom": 'T<"clear">lfrtip', "oTableTools": { "sSwfPath": "${resource(dir: 'swf', file: 'copy_csv_xls_pdf.swf')}", "aButtons": [ { "sExtends":"xls", "mColumns":[0,1,2,3,4] }, { "sExtends": "print", "sMessage": "Contract List Enlistment" } ] } }); }) Now i need to format the excel file with column width auto according to content, can anybody help me???

Full code $("#resultstab").dataTable({""bProcessing": true, "bPaginate": true, "bLengthChange": true, "bFilter": false,"bSort": true, "bInfo": true, "bAutoWidth": false, "sPaginationType": "full_numbers", "fnDrawCallback": function() { $('th').each(function(){ if (($(this).hasClass('sorting')) || ($(this).hasClass('sorting_desc'))) { $(this).attr({title: 'Sort Ascending'});} else { $(this).attr({title: 'Sort Descending'}); } }); }});

check this for SUM http://datatables.net/examples/advanced_init/footer_callback.html

Works perfectly. Thanks

What trouble are you having? Do you get an error? Can you post a live.datatables.net demo?

Currently no - but that is a very nice idea. Filtering is DataTables weak spot (now that the API has been sorted out) and a method like this would really help. I've added it to my ideas list for filtering. Allan
