使用 jquery 在 HTML 表中追加行不起作用

Question

我正在使用for 循环使用jquery 在我的HTML 表中追加多行。

for 循环（下面的代码） 在返回 array of arrays 的 ajax 调用的响应上运行。但无论否，只有 1 行被添加到表中。数组中的元素。

实际响应对象很大，所以附上Google Drive link for a reference

如何追加表格中的所有行？

代码 sn-p（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++) {

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% 的问题都可以通过显示的错误字符串得到解决。为了理解真正的问题，我做了同样的事情:)
