        "destroy": true,
        language: {
            processing: "<img src='" + $('#ajaxImageUrl').val() + "'/>"
        },
        "processing": true,
        "serverSide": true,
        "columnDefs": [{
            "targets": 0,
            "orderable": false
        }],
        "ajax": {
            url: 'url',
            type: "post",
            beforeSend:function(jqXHR, settings){
                if(settings.nTable.jqXHR)
                    settings.nTable.jqXHR.abort();
            },
            xhr: function() {
                var xhr = $.ajaxSettings.xhr();
                xhr.onreadystatechange = function(){
                    //code
                }
                xhr.upload.onprogress = function(e) {
                    setDesign();
                     xhrCount++;
                };
                return xhr;
            },
        }
    });
