怎么table标签中当加载了数据库中的数据后，
<script type="text/javascript" src="js/jquery-1.8.3.js"></script>
<script type="text/javascript">
$(function(){
function intinews(){//使用ajax技术获取新闻列表数据
$.ajax({
"url" :"NewServlet",
"type" :"post",
"dataType" :"json",
"success" :preosn
});
/*function(data){
var $list=$(data);
$list.each(function(){
$("#news").append(this.en_id+":"+this.en_title+" ");
});
});*/
}
function preosn(data){
// var $list=$(data);
// var $newlist=$("#news").empty();
//for(var i=0;i<data.length;i++){
// $newlist.append("<h3>编号："+data[i].en_id+"<span>内容："+data[i].en_title+"</h3>")
//}
var $newlist=$("#news>table").empty();
for(var i=0;i<data.length;i++){
//$newlist.append("<tr><td>编号：</td><td>"+data[i].en_id+"</td><td>内容：</td><td>"+data[i].en_title+"</td></tr>")
$newlist.append("<tr><td>"+data[i].en_id+"</td><td>"+data[i].en_title+"</td></tr>")
}
}
intinews();//执行新闻列表初始化工作
});
</script>
</head>
<body>
<div id="news">
<table border="1">
<tr>
<td>编号</td>
<td>内容</td>
</tr>
</table>
</div>
为何表格的标题不出来，当没有加载数据库中的数据时可以显示
