Layui基于treetable.js树形表格插件，通过调用json获取表格动态数据，支持全部展开、全部折叠、刷新表格、修改、删除等表格功能。扩展：菜单管理、深度测试、自定义图标、多表格、搜索功能等5种实例。

使用方法

1、引入模块layui

layui.config({
    base: 'module/'
}).extend({
    treetable: 'treetable-lay/treetable'
}).use(['treetable'], function () {
    var treetable = layui.treetable;
    
});

2、渲染表格

<table id="table1" class="layui-table" lay-filter="table1"></table>

<script>
layui.use(['treetable'], function () {
    var treetable = layui.treetable;
    
    // 渲染表格
    treetable.render({
        treeColIndex: 2,          // treetable新增参数
        treeSpid: -1,             // treetable新增参数
        treeIdName: 'd_id',       // treetable新增参数
        treePidName: 'd_pid',     // treetable新增参数
        treeDefaultClose: true,   // treetable新增参数
        treeLinkage: true,        // treetable新增参数
        elem: '#table1',
        url: 'json/data1.json',
        cols: [[
            {type: 'numbers'},
            {field: 'id', title: 'id'},
            {field: 'name', title: 'name'},
            {field: 'sex', title: 'sex'},
            {field: 'pid', title: 'pid'},
        ]]
    });
});
</script>

3、数据格式

{
  "code": 0,
  "msg": "ok",
  "data": [{
      "id": 1,
      "name": "xx",
      "sex": "male",
      "pid": -1
    },{
      "id": 2,
      "name": "xx",
      "sex": "male",
      "pid": 1
    }
  ]
}
