Ant Design Vue实现a-table表格单元格合并

参考Ant design Vue官网关于行和列合并api
https://antdv.com/components/table-cn/
下面官网对表格合并这块的描述

！！！注意注意注意重要事情说三遍：很多同学都习惯性的将columns写在data外，如果使用表格合并，会报错，提示缺少‘h’，定义的columns一定要写在data中，否则在加载过程中由于渲染顺序会导致其中的渲染函数无法识别

<template>
  <a-table :columns="columns" :data-source="data" bordered>
    <template slot="name" slot-scope="text">
      <a>{{ text }}</a>
    </template>
  </a-table>
</template>
<script>

const renderContent = (value, row, index) => {
  const obj = {
    children: value, \\ 这是渲染列的值，支持渲染html
    attrs: {}, \\ 属性有colSpan和 rowSpan， colSpan 或者 rowSpan 设值为 0 时，设置的表格不会渲染。设置的值为多少代表合并的行列为多少
  };
  if (index === 4) {
    obj.attrs.colSpan = 0; \\ 如果下标是4，改列不渲染
  }
  return obj;
};

const data = [
