                    <label class="pos-rel">
                        <input type="checkbox" class="ace" />
                        <span class="lbl"></span>
                    </label>

                    .DataTable({
                        bAutoWidth: false,
                        "processing": false, // for show progress bar
                        "serverSide": false, // for process server side
                        "filter": true, // this is for disable filter (search box)
                        "ajax": {
                            "url": "/Customer/LoadData",
                            "type": "GET",
                            "contentType": "application/json",
                            "datatype": "json",
                            "dataSrc": "data"
                        },                    
                        "aoColumnDefs": [
                            {
                                "bSortable": false, "aTargets": [0], "class":"center", "mRender": function (data, type, full) {
                                    return '<label class="pos-rel"><input type="checkbox" class="ace" /><span class="lbl"></span></label>';
                                }
                            },
                                { "data": "customerID", "aTargets": [1] },
                                { "data": "companyName", "aTargets": [2] },
                                { "data": "contactName", "aTargets": [3] },
                                { "data": "address", "aTargets": [4] },
                                { "data": "city", "aTargets": [5] },
                            {
                                "bSortable": false, "aTargets": [6]
                            }
                            ],                       

                        select: {
                            style: 'multi'
                        }
                    });
