当标头不固定并导出到excel时如何绑定数组数据jquery数据表？

Question

我正在通过以下方式获取数据

0: {p3_WoNo: "50446689"}
1: {p3_WoNo: "10842556"}
2: {p3_WoNo: "210001"}
3: {p3_WotType: "2"}
4: {p3_WotType: "2"}
5: {p3_WotType: "2"}

这里的头不是固定的，它总是在不同情况下变化。我绑定绑定动态绑定到下面的jQuery数据表。我通过以下代码为表创建标题和正文。

具有行的数据表未绑定。 未给定error.length。当标头不固定时，如何绑定数组数据jquery数据表。

function bindDataInlabel(result, wotype) {
    if ($.fn.DataTable.isDataTable('#customSearch')) {
        $("#customSearch").DataTable().destroy();
    }
    var UserId = localStorage.UserId;
    var WOValue = [];
    var options = '';
    //var customSearch=
    var tableBody = "";
    var tableHead = "";
    var columns = [];
    var result = result;
    var wotype = wotype;
    $("#customSearch thead").empty();
    $("#customSearch body").empty();

    customSearch = $("#customSearch").dataTable({
        "info": false,
        "bInfo": true,
        "bProcessing": false,
        "iDisplayLength": 10,
        // "lengthMenu": [[10, 25, 50, 100], [10, 25, 50, 100]],
        "bFilter": false,
        "bSearchable": false,
        "aaSorting": [],
        "dom": 'B<lfrtip>',
        "bProcessing": true,
        "ajax": {
            type: 'GET',
            "url": P3Server + 'CustomSearch/labeldata?Userid=' + UserId + '&dataLabel=' + result + '&woType=' + wotype,
            "dataSrc": function (data) {
                tableBody = tableBody + "<tr>";
                for (var prop in data.LabelData[0]) {
                    if (data.LabelData[0].hasOwnProperty(prop)) {
                        // Append properties such as email, fname, lname etc.
                        tableBody = tableBody + ("<th>" + prop + "</th>");
                        // Also keep a list of columns, that can be used later to get column values from the 'data' object.
                        columns.push(prop);
                    }
                }
                tableBody = tableBody + "</tr>";

                // Create the data rows.
                if (data.LabelData.length>0) {
                    data.LabelData.forEach(function (row) {
                        // Create a new row in the table for every element in the data array.
                        tableBody = tableBody + "<tr>";
                        columns.forEach(function (cell) {
                            // Cell is the property name of every column.
                            // row[cell] gives us the value of that cell.
                            tableBody = tableBody + "<td>" + row[cell] + "</td>";
                        });
                        tableBody = tableBody + "</tr>";
                    });
                    $("#customSearch").append(tableBody);
                }
            }
        },
        "fnInitComplete": function (oSettings) {
        },
        "buttons": [
            {
              extend: 'excelHtml5',
              title: 'Documents List'
            },
        ]
    })
}

如何修复此错误以及如何导出到该数据表的excel中。我正在成功获取数据，但是无法转换为绑定数据。 成功执行ajax调用后，数据将绑定data.labelData
