</head>
<body>
[...]
<!-- show tree -->
<div id="tree">...</div>
[...]
</body>
</html>
总结：1）将body中的div换成table就会出现上边不同的结果，最右边结果
2）对数的具体操作：
//获取Id为tree的Fancytree对象
$("#tree").fancytree("getTree") //获取tree的根节点
$("#tree").fancytree("getRootNode") //访问每个节点并把节点展开
$("#tree").fancytree("getRootNode").visit(function(node) {
node.setExpanded(true);
