Vue中使用Element的Table组件实现嵌套表格

<template>
  <div>
    <el-table :data="tableData" style="width: 100%">
      <el-table-column prop="name" label="姓名"></el-table-column>
      <el-table-column prop="age" label="年龄"></el-table-column>
      <el-table-column type="expand">
        <template slot-scope="{ row }">
          <el-table :data="row.subData" style="width: 100%" v-if="row.subData.length > 0">
            <el-table-column prop="subName" label="子项目"></el-table-column>
          </el-table>
        </template>
      </el-table-column>
    </el-table>
  </div>
</template>

<script>
export default {
  data() {
    return {
      tableData: [
        { name: '张三', age: 20, subData: [{ subName: '子项目1' }, { subName: '子项目2' }] },
        { name: '李四', age: 30, subData: [{ subName: '子项目3' }] }
      ]
    };
  }
};
</script>
