element table批量删除

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=" 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>
