What it wants to do is like this:


I’ll just put the code directly, it’s too much to explain one after another.

Structure of the code:


Components

<!-- ElTableColumnPro.vue -->
<template>
   <el-table-column v-if="visible" :formatter="formatter" :align=&#39;align&#39; :prop="prop" :header-align="headerAlign" :label="label" :width="width" :render-header="renderHeader" >
     <template slot-scope="scope">
      <slot :row="scope.row" :$index="scope.$index" >
       <span>{{fomatMethod(scope.row[prop])}}</span>
      </slot>
     </template>
   </el-table-column>
