这样的json数据格式,jquery如何操作?

返回json数据格式是这样的
{ "TABLE":[{ "ROW":[ { "COL":[ {"DATA":"1"},{"DATA":"1.征求网上对话栏目的意见"},{"DATA":""},{"DATA":"1"},{"DATA":"2009-12-9 15:57:13"}]}, { "COL":[ {"DATA":"2"},{"DATA":"2.征求公众留言栏目的意见"},{"DATA":""},{"DATA":"1"},{"DATA":"2009-12-8 15:57:54"}]}, { "COL":[ {"DATA":"3"},{"DATA":"3.网站进行改版整合 征求您的意见"},{"DATA":""},{"DATA":"1"},{"DATA":"2009-12-7 15:58:06"}]} ]}]}

$().ready(function() {
    var loading_html = "<li>正在获取数据,请稍候...</li>";
        $("#proaa1").html(loading_html);
        $.ajax({
            type: "get",
            url: "Services/GetBoardList.ashx",           
            dataType: 'json',
            async: false,
            success: function(msg) {
               var str_html = "";
               $.each(msg.TABLE, function(i, n) {
               str_html += "<li><a href='downDetails.aspx' class='main'>" + n.Subject + "</a></li>";
           }); 
               $("#proaa1").html(str_html);
            
            }
    });
    });

$.each(msg.TABLE, function(i, n) {
这里怎以写??

我一般不用jquery的解析
可以考虑用json2来做喔   直接解析成js对象
