<template>
  <el-table :data="tableData" style="width: 100%">
    <el-table-column prop="name" width="150"></el-table-column>
    <el-table-column prop="date" label="2022-09-25（动态）" width="150">
      <el-table-column prop="state" label="State（动态）" width="120" />
      <el-table-column prop="city" label="City（动态）" width="120" />
      <el-table-column prop="address" label="Address（动态）" />
      <el-table-column prop="zip" label="Zip" width="120" />
    </el-table-column>
    <el-table-column label="2022-09-25">
      <el-table-column prop="state" label="State" width="120" />
      <el-table-column prop="city" label="City" width="120" />
      <el-table-column prop="address" label="Address" />
      <el-table-column prop="zip" label="Zip" width="120" />
    </el-table-column>
  </el-table>
</template>

<script lang="ts" setup>
const tableData = [
  {
    date: '2016-05-03',
    name: '公司1',
    state: 'California',
    city: 'Los Angeles',
    address: 'No. 189, Grove St, Los Angeles',
    zip: 'CA 90036' /*  */,
  },
  {
    date: '2016-05-02',
    name: '公司2',
    state: 'California',
    city: 'Los Angeles',
    address: 'No. 189, Grove St, Los Angeles',
    zip: 'CA 90036',
  },
]

// const renderHeader = ({ column, $index }) => {
//   return <h1>123</h1>
// }
</script>
