Datatables ajax返回的数据顺序与表格中的数据顺序不一致

Question

项目中Datatables是采用Ajax作为数据源的，当ajax返回数据后，我查看ajax返回的数据发现，ajax返回的数据顺序与datatables表格中显示的数据顺序不一致，请问如何才能这两者显示一致呢？
下面是ajax返回的数据

{
    "data":    [{
            "item":    1,
            "sn":    "1",
            "bus":    "1",
            "id":    "1",
            "alise":    "Device_Alias",
            "opcode":    "3",
            "addr_start":    "1",
            "addr_len":    "1",
            "addr_mapping_head":    "0",
            "MBstatus":    0
        }, {
            "item":    1,
            "sn":    "3",
            "bus":    "1",
            "id":    "1",
            "alise":    "Device_Alias",
            "opcode":    "3",
            "addr_start":    "1",
            "addr_len":    "1",
            "addr_mapping_head":    "2",
            "MBstatus":    0
        }, {
            "item":    1,
            "sn":    "2",
            "bus":    "1",
            "id":    "1",
            "alise":    "Device_Alias2",
            "opcode":    "3",
            "addr_start":    "1",
            "addr_len":    "1",
            "addr_mapping_head":    "3",
            "MBstatus":    0
        }]
}

下面是表格中的数据

根据ajax的返回Device_Alias2应该在最下面才对，而在表格中却在中间位置。

代码中关于Datatables的配置如下：

var columns_en = [
        {title: "SN", data: "sn", name: "sn", orderable: false, searchable: false, visible: false},
        {title: "Item", data: "item", name: "item", orderable: true, width: "8%"},
        {title: "Serial Port", data: "bus", name: "port", orderable: true, width: "12%"},
        {title: "Slave ID", data: "id", name: "id", orderable: true, width: "10%"},
        {title: "Alias", data: "alise", name: "alias", orderable: true, width: "12%"},
        {title: "Function", data: "opcode", name: "function", orderable: true, width: "8%"},
        {title: "Data Address", data: "addr_start", name: "address", orderable: true, width: "15%"},
        {title: "Data Length", data: "addr_len", name: "length", orderable: true, width: "15%"},
        {title: "Mapping Address Head", data: "addr_mapping_head", name: "mapping", orderable: true, width: "20%"},
    ];

table = $(TableId).DataTable({
            dom: 'lBfrtip',
            buttons: [
                {
                    extend: 'collection',
                    text: i18ns['export'][lang],
                    buttons: [
                        'copy',
                        'excel',
                        'csv',
                        'pdf',
                        'print'
                    ]
                }
            ],
            autoWith: false,        //自适应宽度
            searching: true,     //过滤功能
            destroy: true,     //允许重新实例化Datatables
            processing: true,   //显示加载信息
            info: true,          //页脚信息
            paging: true,         //翻页功能
            pagingType: "full_numbers",    //显示数字的翻页样式
            lengthChange: true, //允许改变每页显示的数据条数
            pageLength: 50,      //默认每页数据条数
            lengthMenu: [[10, 20, 50, 100, -1], [10, 20, 50, 100, "All"]],//自定义每页显示的行数
            language: {
                processing: "<img src='/images/loading.gif'/><span style='color:blue; font-size:36px;'><b>Data Updating...</b></span>",
                lengthMenu: i18ns['lengthmenu'][lang],
                zeroRecords: i18ns['norecord'][lang],
                emptyTable: i18ns['norecord'][lang],
                info: "Showing _START_ to _END_ of _TOTAL_ entries",
                infoFiltered: "Have _MAX_ Records in database",
                search: i18ns['search'][lang],
                paginate: {
                    first: i18ns['firstpage'][lang],
                    previous: i18ns['prev'][lang],
                    next: i18ns['next'][lang],
                    last: i18ns['lastpage'][lang]
                }
            }, //多语言配置
            columns: columns_en,
            ajax: {
                url: DataUrl,
                dataSrc: "data",
            },
            initComplete: function () {
            },
            rowCallback: function (nRow, data, iDisplayIndex) {
                data['item'] = iDisplayIndex+1;
                $("td", nRow).eq(0).html(data["item"]);
                return nRow;
            }
        });

请问下应该如何修改，才能让顺序一致？

Answer 1

解决了吗?我今天遇到一模一样的问题..
更新:额.加入bSort:false就可以了

Answer 2

不指定ajax
