    handleDisable(row,index){

   //返回true或false

  }，

    handleSelectionChange(val){

        this.chek = val;

    },

          <el-table-column type="selection" width="40px"></el-table-column>  

    handleSelectionChange(val){

      if(val.length > 1){

        this.$refs.tb.clearSelection()

        this.$refs.tb.toggleRowSelection(val.pop())

      }else{

        this.chek = val;

      }  

    },

    onSelectAll () {

      this.$refs.tb.clearSelection()
