Vue组件有可能需要多个道具中的一个吗？

<template>
  <div>
    <p>propA: {{ propA }}</p>
    <p>propB: {{ propB }}</p>
  </div>
</template>

<script>
export default {
  props: {
    propA: {
      type: String,
      required: true
    },
    propB: {
      type: Number,
      default: 0
    }
  }
}
</script>

<template>
  <div>
    <child-component v-bind:propA="valueA" v-bind:propB="valueB" />
  </div>
</template>

<script>
import ChildComponent from './ChildComponent.vue'

export default {
  components: {
    ChildComponent
  },
  data() {
    return {
      valueA: 'Hello',
      valueB: 123
    }
  }
}
</script>
