datatable无法显示Ajax从后台获取的Json数据

Question

js:

$(function () {
    $(function () {
        $(document).ready(function () {
            if ($.fn.DataTable.isDataTable('#dataTable')) {
                $('#dataTable').dataTable().fnDestroy();
                $('#dataTable').dataTable().empty();

            }

            $("#dataTable").DataTable(
                {
                    "serverSide": true,
                    "processing": true,
                    "filter": true,
                    "ajax":
                    {
                        url: "api/CinvoiceList",
                        method: "Post",
                        
                        datatype: "json",
                        //success: function (data) {
                         //   alert(JSON.stringify(data));
                        //},
                    },
                    "columnDefs": [{
                        "targets": [0],
                        "visible": true,
                        "searchable": true
                    }],
                     
                    "columns": [
                        { "data": "id", "name": "Id", "autoWidth": true },
                        { "data": "cinvoice_Id", "name": "Cinvoice_Id", "autoWidth": true },
                        { "data": "cinvoice_Num", "name": "Cinvoice_Num", "autoWidth": true },
                ...省略一些...   
                    ]
                });

        });

    });
});

如图，后台能传过来数据，但是表一直显示没有匹配的项。不知道原因在哪，请帮忙看看， 谢谢！

你给他设置的值应该是 result.data
