Question

I added plugin

$.fn.dataTableExt.oApi.fnGetColumnData

Can be found here: http://datatables.net/plug-ins/api

After I executed

$(document).ready(function () { 
var oDataTable = $("#usersGrid").dataTable();
//... 
} 

Microsoft JScript runtime error: Unable to get value of the property
‘asSorting’: object is null or undefined.

What can be a reason?
P.S.: It’s not fnGetColumnData problem but another one which connected with $("#usersGrid").dataTable();

$('#example').dataTable({
            "sDom": 'R<"H"lfr>t<"F"ip<',
            "bJQueryUI": true,
            "bFilter": true,
            "sPaginationType": "full_numbers",
            "aoColumns": [
                { "sTitle": "A" },
                { "sTitle": "B" },
                { "sTitle": "C" }
            ]
        });

I think that this has something to do with your markup. Remember that dataTables needs an html table with <thead> section with a <th> for each column. If you are trying to initialize an empty table you should try

$('#usersGrid').dataTable({
  aoData: [{}]
});
