如何解决数据表-下滑-我在做什么错？ -N.B我只在学习PHP和JQuery

我是PHP和Ajax的新手。说实话，对JQuery或Datatables并不那么了解。我正在尝试做的。单击表，然后可以从选定的行中运行另一个查询。即将参数传递给PHP，以便我可以运行查询。然后，我想将此查询的结果返回到数据表中的幻灯片中。原始表正在填充。当我单击时，功能启动。任何帮助将不胜感激。预先感谢。

    $('#giftcards tbody').on('click','tr',function () {
        var data = table.row( this ).data();
        //alert(data);
        var num = data[0];
        //alert(num);
        var tr = $(this).closest('tr');
        var row = table.row( tr );
         //alert( '1. You clicked on '+num+'\'s row' );
        //format ( d );
          $.ajax({
             type: "POST",url: 'details.PHP',data: {number: num},success: function(data){
             //alert('response from PHP ' + data);
             //$('#result').html(response);
            }
              });
            if ( row.child.isShown() ) {
            // This row is already open - close it
            $('div.slider',row.child()).slideUp( function () {
                row.child.hide();
                tr.removeClass('shown');
            } );
            }
        else {
            // Open this row
            row.child( format( data ),'no-padding' ).show();
            tr.addClass('shown');
            $('div.slider',row.child()).slideDown();
          } 
              
        });

下面的格式功能用于桌面滑块

<script>
function format ( d ) {
    // `d` is the original data object for the row
     return '<div class="slider">'+
    alert('In format func ' + d)
     '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">'+
        '<tr>'+
            '<td>Customer Number:</td>'+
            '<td>'+d.number+'</td>'+
        '</tr>'+
        '<tr>'+
            '<td>Customer Name:</td>'+
            '<td>'+d.Name+'</td>'+
        '</tr>'+
        '<tr>'+
            '<td>Extra info:</td>'+
            '<td>And any further details here (images etc)...</td>'+
        '</tr>'+
    '</table>';
}
 
</script>

下表样本数据-N.B.该表是使用PHP构建的查询表
