考虑到会有自定义的需求，希望能开放这样的api

<template #headerCell="{ column }">
      <template v-if="column.key === 'name'">
        <span>
          <smile-outlined />
          Name
        </span>
      </template>
    </template>
    <template #bodyCell="{ column, record }">
      <template v-if="column.key === 'name'">
        <a>
          {{ record.name }}
        </a>
      </template>
   </template>

这样就能彻底通过columns这个api管理列名 @Javey
