In the project, Datatables uses Ajax as the data source. When ajax returns the data, I check the data returned by ajax It was found that the order of data returned by ajax is inconsistent with the order of data displayed in the datatables table. How can I make the two display consistent?
The following is the data returned by ajax

{
    "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
        }]
}

The following is the data in the table

According to the return of ajaxDevice_Alias2 should be at the bottom, but in the table it is in the middle.

The configuration of Datatables in the code is as follows:

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,        //自適應寬度
            searching: true,     //過濾功能
            destroy: true,     //允許重新實例化Datatables
            processing: true,   //顯示加載信息
            info: true,          //頁腳信息
            paging: true,         //翻頁功能
            pagingType: "full_numbers",    //顯示數(shù)字的翻頁樣式
            lengthChange: true, //允許改變每頁顯示的數(shù)據(jù)條數(shù)
            pageLength: 50,      //默認每頁數(shù)據(jù)條數(shù)
            lengthMenu: [[10, 20, 50, 100, -1], [10, 20, 50, 100, "All"]],//自定義每頁顯示的行數(shù)
            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]
                }
            }, //多語言配置
            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;
            }
        });

How should I modify it so that the order is consistent?
