一、el-table加上@selection-change="selectedChange"，并加上<el-table-column type="selection" width="40" align="center"></el-table-column>选择行
<el-table ref="selectList" :data="listData" border stripe fit highlight-current-row style="width: 100%;margin-top:20px" @selection-change="selectedChange">
<el-table-column type="selection" width="40" align="center"></el-table-column>
<el-table-column v-for="(item, index) in columns" :key="index" align="center" :prop="item.key" :label="item.value">
<template slot-scope="scope">
<p>
{{ scope.row[item.key] }}
</p>
</template>
</el-table-column>
</el-table>
二、methods加上方法：
selectedChange(selection) {
this.selectList = [];
if (selection.length > 1) {
this.$refs.selectList.clearSelection();
this.$refs.selectList.toggleRowSelection(
selection[selection.length - 1]
);
}
this.selectList = [selection[selection.length - 1]];
},
三、隐藏全选的按钮
/deep/ .el-table__header-wrapper .el-checkbox {
//找到表头那一行，然后把里面的复选框隐藏掉
display: none;
}
