实现思路:

　　1. table 添加  ref="refTable" 引用 该table

　　2. table 添加  @row-click="clickTable" 点击事件

　　3. 点击时,调用table的方法 toggleRowExpansion ,展开/关闭

　　参考API :  https://element.eleme.cn/#/zh-CN/component/table
　　

clickTable(row,index,e){
 
    //调用,table的方法,展开/折叠 行
    this.$refs.refTable.toggleRowExpansion(row)
}

 此处贴的是别人的代码:

<template>
  <el-table
    :data="tableData5"
  @row-click="clickTable"
   ref="refTable"
    style=" 100%">
    <el-table-column type="expand">
      <template slot-scope="props">
        <el-form label-position="left" inline class="demo-table-expand">
          <el-form-item label="商品名称">
            <span>{{ props.row.name }}</span>
          </el-form-item>
          <el-form-item label="所属店铺">
            <span>{{ props.row.shop }}</span>
          </el-form-item>
          <el-form-item label="商品 ID">
            <span>{{ props.row.id }}</span>
