项目中有如下需求：

可以添加一个列表 => 添加弹框 => 里面可以添加多个产品（产品里面可以添加多个对接人跟政策），所以数据结构应该如下

ruleForm: {
        companyName: '', // 公司名称
        financialProduct: [
          // 产品数组
          {
            productName: '', // 产品名称
            dockingPerson: [
              // 对接人
              {
                dockingName: '', // 联系人
              }
            ],
            financialPolicy: [
              // 返利政策
              {
                makeWay: '', // 计提条件
              }
            ]
          }
        ]
      },

但是在提交表单的时候验证不了，rule不起作用，因为数据是循环出来的，所以不起作用，解决办法如下

<template>
  <div class="addProduct_wrapper">
      <!-- 中间内容区域 -->
      <div class="center_content">
        <el-form
          ref="ruleForm"
          :model="ruleForm"
          label-width="80px"
          :rules="rules">
          <!-- 上方的列表 -->
          <div class="basic_info">
            <div class="info_box">
              <el-form-item label="公司名称" prop="companyName">
                <el-input placeholder="请输入公司的名称" v-model="ruleForm.companyName"></el-input>
              </el-form-item>
            </div>
          <!-- 产品盒子 -->
          <div class="product_box" v-for="(item, index) in ruleForm.financialProduct" :key="index">
            <!-- 关闭按钮 -->
            <span class="closeBtn" @click="delateProduct(index)" v-if="index !== 0">X</span>
            <!-- 产品详情 -->
            <div class="product_detail">
              <el-form-item label="产品详情"></el-form-item>
