因为之前将下面这段代码放错了位置  导致一直报错，且无法触发事件

有两个注意事项：1、下面的程序中tool(demo)  中的demo是table表的lay-filter的名字  如我的代码中：所以我需要将下面的那个demo改为test

2、关于这段代码放的位置，千万不要把它放到js文件里面去，一般你导入layui时，一般是通过<script></script>中间存放use table

 它应该放的位置如下图所示：  不要放到layui.use() 的括号外面去了

 layui.use('table', function(){ table.on()放的位置  })

 放到外面去的话，浏览器会出现这个错误（这个耽误了我很久）：

 //编辑，删除，发布申请
     table.on('tool(demo)', function(obj){
         var data = obj.data;
         // console.log(data)

Uncaught ReferenceError: table is not defined这个错误  笔者遇到的是因为将table.on放错了位置（放于table.use()外面去了）
