element-ui Checkbox 实现单选

html 部分

<el-table id="tables" ref="multipleTable" row-key="id" :data="tableData" max-height="450" border style="width: 100%" @selection-change="handleSelectionChange" //将用到此 :header-cell-style="{background:'#F8F8FA',color:'#606266',fontSize:'13px',fontWeight:'bold'}"
   >
     <el-table-column type="selection" width="60" align="center" :reserve-selection="true"></el-table-column>
     <el-table-column prop="id" label="序号" width="120" align="center"> </el-table-column>
     <el-table-column prop="name" label="话题名称" align="center" show-overflow-tooltip> </el-table-column>
 </el-table>

js部分

handleSelectionChange(val) { if(val.length >=2){ // 删除索引为0的 // console.log(val.splice(0,val.length-1),'被删除的')
     let arrays = val.splice(0,val.length-1) arrays.forEach(row => { this.$refs.multipleTable.toggleRowSelection(row); //除了当前点击的，其他的全部取消选中
 }) } // console.log(val,'最后得到的')this.array = val }
