                </tr>
            </thead>
        </table>

And this is my script . I use lasted DataTable 1.10.6

   var table = $('#div_table').DataTable({
                "processing": false,
                "serverSide": false,
                "ajax": {
                    "url": "../BUS/WebService.asmx/LIST_LOCATION",
                    dataSrc: function (json) {
                        return $.parseJSON(json.d);
                    },
                    "dataType": "json",
                    "contentType": "application/json; charset=utf-8",
                    "type": "POST"
                },             
                "aoColumns": [  //// 7 columns as Datatable
                    { "mData": null, "aTargets": [0], "sType": "integer", "bSearchable": false, "orderable": false },
                    { "mData": "LOCATION_NAME", "aTargets": [1], "sType": "string" },
                    { "mData": "LOCATION_DES", "aTargets": [2], "sType": "string" },
                    { "mData": "LOCATION_ID", "aTargets": [3], "sType": "string", "bVisible": false, "bSearchable": false, "orderable": false },
                    { "mData": "AREA_ID", "aTargets": [4], "sType": "string", "bVisible": false, "bSearchable": false, "orderable": false },
                    { "mData": "EDIT_DATE", "aTargets": [5], "sType": "date", "bVisible": false, "bSearchable": false, "orderable": false },
                    { "mData": "EDIT_BY", "aTargets": [6], "sType": "string", "bVisible": false, "bSearchable": false, "orderable": false }
                ],
                "order": [[1, 'asc']]
            });        
            ////table.columns([3, 4, 5, 6]).visible(false);   //// disable column 4,5,6,7
            //// create index column 1
            table.on('order.dt search.dt', function () {
                table.column(0, { search: 'applied', order: 'applied' }).nodes().each(function (cell, i) {
                    cell.innerHTML = i + 1;
                });
            }).draw();
            $('#div_table tbody').on('click', 'tr', function () {     // get full data or some columns at row selected
                $(this).toggleClass('selected');
                var data_ = table.row($(this)).data();
                alert(data_[3] + " and " + data_[4]);
                /// alert(table.row($(this)).data()); error it show info "object object"
            });

Run it, i get error "undefined and undefined"
