很小的一个问题，但是有细节需要注意
（1）问题：在起初我写的时候是根据元素的name是否相同判断是否是同一个节点，出现的问题就是，如果说两个元素的name相同，就会判断出错
（2）代码：
<template>
<div class="main">
<div style="margin-top: 20px">
<el-button @click="handleDelete()" type="danger">批量删除</el-button>
</div>
<template>
<el-table
class="mytable"
:data="tableData"
stripe
style="width: 50%"
@selection-change="handleSelectionChange"
>
<el-table-column type="selection" width="50"></el-table-column>
<el-table-column
prop="date"
label="日期"
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
width="180">
</el-table-column>
<el-table-column
prop="address"
label="地址">
</el-table-column>
</el-table>
</template>
</div>
</template>
<script>
export default {
data() {
return {
