vue中如何实现动态属性

<kf-table :[propName]="tableColumn" @[propName]="tableColumn"  :searchParams="searchParams" immediateLoad />

computed: {
	propName() {
	  const propNameMap = {
	    'dynamictable': 'tableColumn',
	    'dynamicdatatable': 'tableRow',
	  }
	  return propNameMap[this.popupItem.type] || propNameMap[this.popupItem.operateType];
	}
}
