  var form = layui.form,
      number = layui.number;
});
</script></code>

<code class="html"><table id="test" lay-filter="test">
  <thead>
    <tr>

      <td>张三</td>
      <td>zhangsan@qq.com</td>
      <td><input type="number" name="age" lay-verify="number" value="18" /></td>

<code class="html"><script>
layui.use(['table'], function(){
  var table = layui.table;
  
  table.render({
    elem: '#test',
    cols: [[
      {field:'id', width:80, edit:'text'},
      {field:'username', width:120, edit:'text'},
