实现多选非常简单: 手动添加一个el-table-column，设type属性为selection即可；默认情况下若内容过多会折行显示，若需要单行显示可以使用show-overflow-tooltip属性，它接受一个Boolean，为true时多余的内容会在 hover 时以 tooltip 的形式显示出来。<template><el-tableref="multipleTable":data="tableData3"tooltip-effect="dark"style="width: 100%"@selection-change="handleSelectionChange"><el-table-columntype="selection"width="55"></el-table-column><el-table-columnlabel="日期"width="120"><template slot-scope="scope">{{ scope.row.date }}</template></el-table-column><el-table-columnprop="name"label="姓名"width="120"></el-table-column><el-table-columnprop="address"label="地址"show-overflow-tooltip></el-table-column></el-table><div style="margin-top: 20px"><el-button @click="toggleSelection([tableData3[1], tableData3[2]])">切换第二、第三行的选中状态</el-button><el-button @click="toggleSelection()">取消选择</el-button></div>
