element-plus 多选框的问题

Question

问题遇到的现象和发生背景

element-plus + vite

我的解答思路和尝试过的方法

我采用selection-change的方法可以一起选中，但是取消不了

我想要达到的结果

表格内容数据有相同的id
要求是选中其中一个id，其他的相同的id数据也全部选中，取消则一起取消
有更好的方法推荐一下

参考这个：example-多选

<template>
  <el-table
    ref="multipleTableRef"
    :data="tableData"
    style="width: 100%"
    @select="handleSelect"
  >
    <el-table-column type="selection" width="55" />
    <el-table-column label="Date" width="120">
      <template #default="scope">{{ scope.row.date }}</template>
    </el-table-column>
    <el-table-column property="name" label="Name" width="120" />
    <el-table-column property="address" label="Address" show-overflow-tooltip />
  </el-table>
</template>

<script lang="ts" setup>
import { ref, toRaw } from 'vue'
import { ElTable } from 'element-plus'

interface User {
  date: string
  name: string
  address: string
}
  
const tableData: User[] = [
  {
    date: '2016-05-03',
    name: 'Tom1',
    address: 'No. 189, Grove St, Los Angeles',
  },
  {
    date: '2016-05-02',
    name: 'Tom1',
    address: 'No. 189, Grove St, Los Angeles',
  },
  {
    date: '2016-05-04',
    name: 'Tom2',
    address: 'No. 189, Grove St, Los Angeles',
  },
  {
    date: '2016-05-01',
    name: 'Tom2',
    address: 'No. 189, Grove St, Los Angeles',
  },
  {
    date: '2016-05-08',
    name: 'Tom',
    address: 'No. 189, Grove St, Los Angeles',
  },
  {
    date: '2016-05-06',
    name: 'Tom',
    address: 'No. 189, Grove St, Los Angeles',
  },
  {
    date: '2016-05-07',
    name: 'Tom',
    address: 'No. 189, Grove St, Los Angeles',
  },
]

const multipleTableRef = ref<InstanceType<typeof ElTable>>()

const handleSelect = (val: User[], row: User) => {
  const data = tableData.forEach(item => {
    if (item.name === row.name && item !== toRaw(row)) {
      multipleTableRef.value.toggleRowSelection(item)
    }
  })
}


</script>
