Summary of common usage of layui table component

table is one of the core components of layui. It is used to perform a series of functions and dynamic data operations on tables, covering almost all needs involved in daily business. Supports fixed headers, fixed rows, fixed column left/column right, supports dragging to change column widths, supports sorting, supports multi-level headers, supports custom templates for cells, and supports table overloading (such as search and conditional filtering) etc.), supports check boxes, supports paging, supports cell editing and many other functions.

An example is compiled below:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>layer学习</title>
    <link href="/Content/mycss.css" rel="stylesheet" />
    <link href="/Content/layui/css/layui.css" rel="stylesheet" />
    <script src="/Content/layui/layui.js"></script>
</head>
<body>
    <!--表格-->
    <div id="myTable" lay-filter="test"></div>
    <!--工具栏-->
    <script type="text/html" id="barDemo">
        <a class="layui-btn layui-btn-xs" lay-event="edit">编辑</a>
        <a class="layui-btn layui-btn-danger layui-btn-xs" lay-event="del">删除</a>
    </script>
    <script type="text/html" id="allow">
        <!-- 这里的 checked 的状态只是演示 -->
        <input type="checkbox" name="{{d.Id}}" value="{{d.Id}}" title="允许" lay-filter="allowSetFilter"  {{ d.IsAllow == true ? &#39;checked&#39; : &#39;&#39; }}>
