 * 可以在 template 里边定义可复用的组件，DefineLabel，ReuseLabel 是采用的解构赋值，都是 Vue 组件

 * 直接通过组件的形式使用，<DefineLabel v-slot="{ label, hint, hintClick }"> 中间是需要复用的组件代码 <DefineLabel />，通过 <ReuseLabel /> 来使用定义的组件
 * DefineLabel 里边的 v-slot="{ label, hint, hintClick }"相当于是解构了组件的 prop，需要注意的是 boolean 类型，需要显式的赋值比如 <ReuseLabel :flag="true" />
 * 事件也得以 prop 形式传入，不能是 @event的形式，比如下面的 hintClick 需要<ReuseLabel :hintClick="() => { doSomething }"/>
