elementUI用 table多选 实现单选

这是elementui的表格多选

1. 首先隐藏掉多选checkbox

 ::v-deep .el-table__header {
    
    
    .el-checkbox {
    
    
      display: none;
    }
  }

2. 利用table 的selection-change 事件实现单选

<template>
   <el-table
        ref="multipleTable"
        :data="tableData"
        style="width: 100%;"
        class="exam_table"
        @selection-change="handleSelectionChange"
      >
        <el-table-column type="selection" width="55"> </el-table-column>
        <el-table-column label="角色名称" min-width="120" prop="name">
        </el-table-column>
        <el-table-column prop="num" label="成员数量" min-width="120">
        </el-table-column>
      </el-table>
</template>
 
data(){
    
    
    return {
    
    
        tableSelect:[]
    }
},
methods:{
    
    
    handleSelectionChange(val) {
    
    
      if (val.length > 1) {
    
    
        this.$refs.multipleTable.clearSelection();
        this.$refs.multipleTable.toggleRowSelection(val.pop());
      } else {
    
    
        this.tableSelect = val;
      }
    },
}

效果
