parent.vue

<template>
<div>
  <BaseTable :columns="columns" :data-source="data">
    <template #bodyCell="{column, record}">
      <template v-if="column.key === 'name'">
          <a>
            {{ record.name }}

BaseTable.vue

<template>
  <a-table>
    <template v-for="(item,index) in Object.keys($slots)" v-slot:[item]="scoped" :key="index">
      <slot :name="item" v-bind="scoped || {}"></slot>
    </template>  
  </a-table>
</template>
<script setup>
import { useSlots, createApp, h } from 'vue'
const slots = useSlots()

const continer = document.createElement('div')
const prop = {
  column:{
    key:'name'
  },
  record: {
    name: '名字'
  }
  }

// 纯粹的vnode
// console.log(h('div',slots.bodyCell)) 

// vnode挂在到dom上 转成dom
const apps = createApp(slots.bodyCell,prop)
apps.mount(continer)

console.log('con', continer)
</script>

可用于处理想在子组件渲染之前，结合插槽中的内容处理一些逻辑。
