Append rows in HTML table with jquery is not working

I am using a for loop to append multiple rows in my HTML table using jquery.

The for loop (code below) runs on the response of an ajax call which returns an array of arrays. But only 1 row gets added to the table irrespective of no. of elements in the array.

The actual response object is quite large, so I am attaching a Google Drive link for a reference

How do I append all the rows in the table?

Code snippet (using 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>' +

                                        BookBtn + '</td></tr>');

                                }

P.S To quickly debug, you must always check browser console to look for any JSON exceptions. Almost 90% of issues get resolved with the error strings displayed. To understand the real issue, I did the same :)
