在 HTML table 中附加行 jquery 不起作用

Question

我正在使用 for 循环在 HTML table 中使用 jquery 追加多行。

for 循环 （下面的代码） 在 ajax 调用的响应上运行，其中 returns 一个 array of arrays .但是只有 1 行被添加到 table 而不管否。数组中的元素。

实际响应对象比较大，所以附上一个Google Drive link for a reference

如何附加 table 中的所有行？

代码片段（使用Jquery）

$(document).ready(function() {
            $('#ghsubmitbtn').on('click', function(e) {

                var data = JSON.stringify(JSONObj);

                $.ajax({
                    url: 'https://api-crt.cert.havail.sabre.com/v4.2.0/shop/flights?mode=live&limit=50&offset=1',
                    method: 'POST',
                    contentType: "application/json; charset=utf-8",
                    data: data,
                    headers: {
                        "Authorization": 'Bearer ' + bat
                    },

                    success: function(data) {
                        var BookBtn = '<input type="submit" value="Book" name="book" class="btn btn-primary">';

                        for (var v = 0; v <= 999; v++) {
                            for (var b = 0; b <= 999; b++) {
                                for (var m = 0; m <= 999; m++) {

                                    var row = $('<tr><td>' + data.OTA_AirLowFareSearchRS.PricedItineraries.PricedItinerary[v].SequenceNumber + '</td><td>' +

P.S 要快速调试，您必须始终检查 browser console 以查找任何 JSON 异常。几乎 90% 的问题都通过显示的错误字符串得到解决。为了了解真正的问题，我做了同样的事情:)
