el-table单选并隐藏全选框

<el-table
  @selection-change="handleSelectionChange"
  ref="tableRef"
  :header-cell-class-name="cellClass"
>

单选功能：

    handleSelectionChange(selection) {
    
      if (selection.length > 1) {
    
        this.$refs.tableRef.clearSelection();
        this.$refs.tableRef.toggleRowSelection(selection.pop());
      }

    },

隐藏全选框:

cellClass(row){
    
  if (row.columnIndex === 0 && row.rowIndex === 0) {
    
    return 'disableheadselection'
  }
}

<style lang="scss" scoped>
	/deep/ .disableheadselection > .cell .el-checkbox__inner {
    
	  display: none;
	}
<style>

如下图：每次只能勾选一个，不能全选。
