1、效果图

可以全部复制粘贴，也可以单独对某行、某列进行复制粘贴

2、实现代码

html部分：

<template>  <div>    <el-table      :data="tableData"      border      style="width: 100%"      :cell-class-name="getCellIndex"      @paste.native="pasteInfo($event)"      @cell-click="cellClick">      <el-table-column prop="date" align="center" label="日期" width="180">        <template slot-scope="scope">          <el-input v-model="scope.row.date" placeholder="单行输入" clearable />        </template>      </el-table-column>      <el-table-column prop="name" align="center" label="姓名" width="180">        <template slot-scope="scope">          <el-input v-model="scope.row.name" placeholder="单行输入" clearable />        </template>      </el-table-column>      <el-table-column prop="address" align="center" label="地址">        <template slot-scope="scope">          <el-input v-model="scope.row.address" placeholder="单行输入" clearable />        </template>      </el-table-column>      <el-table-column prop="jg" align="center" label="籍贯"></el-table-column>      <el-table-column prop="gz" align="center" label="工作"></el-table-column>      <el-table-column prop="xz" align="center" label="薪资"></el-table-column>      <el-table-column prop="age" align="center" label="年龄">        <template slot-scope="scope">          <el-input v-model="scope.row.age" placeholder="单行输入" clearable />        </template>      </el-table-column>      <el-table-column prop="sex" align="center" label="性别">        <template slot-scope="scope">          <el-input v-model="scope.row.sex" placeholder="单行输入" clearable />        </template>      </el-table-column>      <el-table-column prop="tel" align="center" label="电话">        <template slot-scope="scope">          <el-input v-model="scope.row.tel" placeholder="单行输入" clearable />        </template>      </el-table-column>    </el-table>  </div></template>

js部分：
