layui.use('table', function(){
  var table = layui.table;
  //执行渲染
  table.render({
    elem: '#table1',
    url: '/demo/table/user/',
    cols: [[
      {field:'id', title:'ID', width:80},
      {field:'username', title:'用户名', width:120},
      {field:'email', title:'邮箱', minWidth:150},
      {field:'sex', title:'性别', width:80, sort:true},
      {field:'city', title:'城市', width:100},
      {field:'sign', title:'签名', minWidth:150},
      {field:'status', title:'状态', width:80, templet: '#statusTpl', unresize: true},
      {field:'experience', title:'积分', width:80, sort: true},
      {field:'score', title:'评分', width:80, sort: true},
      {field:'classify', title:'职业', width:100},
      {field:'wealth', title:'财富', width:135, sort: true},
    ]],
    done: function(res, curr, count){
      var bodyHeight = $('.layui-table-main').height(); //获取表格主体的高度
      console.log("表格主体的高度为：" + bodyHeight);
    }
  });
  
});
