vue3 tab切换 动态组件

先看一张图

具体代码：

组件实例信息

如果你把组件实例放到Reactive Vue会给你一个警告：Component which was made a reactive object. This can lead to unnecessary performance overhead, and should be avoided by marking the component with markRaw or using shallowRef instead of ref.
Vue 收到一个组件，它被做成一个反应性对象。这可能会导致不必要的性能开销，应通过使用“markRaw”标记组件或使用“shallowRef”而不是“ref”来避免。
