jquery datatable中的sAjaxSource问题

最近刚接触datatable对此不太熟悉，我知道sAjaxSource后面放url，但是我要请求的url有表头，我不知道怎么加
httprequest = new XMLHttpRequest();
httprequest.open("GET",
"http://123.563:8088/kiunionSer/ws/v1.0/vehicleBaseInfo/searchByEnterprise?enterpriseId=1&start=0&limit=30");
httprequest.setRequestHeader("Authorin", "MDphZG1pbg");
上面是我用ajxa请求的方法，请问在datatable中怎么加("Authorin", "MDphZG1pbg");这两个

ajax是jquery发送的，调用ajaxSetup配置其他请求头即可

       jQuery.ajaxSetup({ headers: { Authorin: 'MDphZG1pbg' } });//////////////////////
            $(document).ready(function() {
                var oTable = $('#example').dataTable( {
                    "bProcessing": true,
                    //"bServerSide": true,
                    "sAjaxSource": "sources/arrays.txt" 
                } );
            } );

写法例子如：
var method = "get";
var url = "test.php";
var async = true;
var data = "username=" + encodeURIComponent(username) + "&password=" + encodeURIComponent(password)
xmlHttp.open(method, url, async);
//设置回调函数,接收服务器端的信息以进行处理
xmlHttp.onreadystatechange = getServerInfo;

xmlHttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlHttp.setRequestHeader("Content-Length", data.length);
xmlHttp.send(data);

知道问题在哪里把？
