layui table不同的值点击执行不同的事件

layui table不同的值点击执行不同的事件，如何实现？
从php后台获取的数据中，状态一栏有待处理和已处理两种状态，如何实现在待处理的时候点击更新数据，而在已处理的时候点击不被执行。

```JavaScript
    
<script src="./layui/layui.all.js" charset="utf-8"></script>
  <script>
    layui.use('table', function () {
      var table = layui.table;
      var laydate = layui.laydate;
      var form = layui.form;
      var $ = layui.jquery;        
      //绑定时间选择器
     laydate.render({
        elem:'#start'
      })
      laydate.render({
       elem:'#end'
      })
        
      var tableIns = table.render({
        elem: '#test1'
        ,url: './demo_data.php'
        ,toolbar: '#toolbarDemo' //开启头部工具栏，并为其绑定左侧模板
        ,title:'demo'
        ,loading:true
        ,height:'full-100'
        //,totalRow: true //开启合计行(在这里开启合计)
        ,cols: [
          [
            {field: 'id', title: 'ID', style: 'font-size:12px'}
          , {field: 'qty', title: '查阅数', align:'center', align:'center'}
          , {field: 'status', title:'状态',style: 'font-size:12px',templet:SetoState,}
          ]
        ],
        where:{
        }
        , page: true
        , limits: [50,100,150,200,250,300,350,400,450,500]
        , limit: 50 //每页默认显示的数量
          
      });

       //头工具栏事件，添加，批量删除
      table.on('toolbar(test1)', function (obj) {
        var checkStatus = table.checkStatus(obj.config.id);
        var data = checkStatus.data;
        console.log(data);
        console.log(checkStatus);
        switch (obj.event) {
        //新增窗口        
          case 'add':
            openAddUser();
          break;
         });

            function SetoState(data) {
        var btn = "";
        var stylede = data.status;
        if (stylede == '待阅') {//如何在待阅的时候，添加点击事件执行update操作？
            btn += '<span style="font-size:12px;color:red;font-weight: bold;cursor: pointer; ">待阅</span>';
        }
        else if(stylede == '已阅'){
            btn += '<span style="font-size:12px;color:#1cbb8c;font-weight: bold;">已阅</span>';
        }
        return btn;
    }
        

后台php数据

<?php
header('Content-type:text/html;charset=utf-8');
// 连接数据库
try {
  $pdo = new PDO('mysql:host=127.0.0.1;dbname=demo;port=3306', 'root', 'root');
} catch (PDOException $e) {
  die('connet error :' . $e->getMessage());
}
$pdo->exec('set names utf8');


if (isset($_GET['page']) && isset($_GET['limit'])) {
  // 分页查询
  $start = ($_GET['page'] - 1) * $_GET['limit'] ;
  $limit = $_GET['limit'];
  $sn = isset($_GET['sn']) ? $_GET['sn']:"%";     //where 条件，这里是姓名做测试，模糊查询
  $data = $pdo->query("SELECT 
  id,
  auther,
  model,
  failure,
  announce_date,
  content,
  sample_picture,
  reader,
  SUM(length(reader)-length(replace(reader,',',''))+1) as qty,
  (case when find_in_set('$ss',reader) >0 then '已阅' else '待阅' end) as status 
  from demotable group by id  order by id desc limit $start, $limit")->fetchAll(PDO::FETCH_ASSOC);
  $num = count($pdo->query("SELECT id FROM demotable")->fetchAll(PDO::FETCH_ASSOC));
  $json = json_encode(array(
    "code" => 0,
    "msg" => "",
    "count" =>  $num,
    "data" => $data
  ), JSON_UNESCAPED_UNICODE); //JSON_UNESCAPED_UNICODE注意不加会乱码
  echo $json;
} 
elseif (isset($_GET['action']) && $_GET['action'] == 'update') {  //前端是待阅读的时候点击需要执行的事件
  $clean = array();
  $clean['id'] = isset($_POST['id']) ? $_POST['id'] : '这个是数据库id';
  $del = $pdo->exec("update demotable set reader = concat('$ss',',',reader) where id ='{$clean['id']}'");
  if($del >0 ){
    echo json_encode(array(
      "code" => 1,
      "msg" => "success",
      "count" =>  $del,
      "data" => array()
    ));
  }else{
    echo json_encode(array(
      "code" => 1,
      "msg" => "error",
      "count" =>  0,
      "data" => array()
    ));
  }

} else {
  // 无参数
  echo json_encode(array(
    "code" => 1,
    "msg" => "error",
    "count" =>  0,
    "data" => array()
  ));
}
 

```

点击的时候把待处理和已处理状态拿到，再去执行不同的事件
