情景：element-ui 二次封装了 el-table 组件，使用封装组件时，想要调用 el-table 组件内置的一些方法。只在封装组件上定义 ref 是拿不到 el-table 内置方法的。解决方法如下。

1. vue2

封装组件

<template><el-table ref="innerComponentRef" v-bind="$attrs"></el-table></template><script>export default {data() {return {};},mounted() {const entries = Object.entries(this.$refs.innerComponentRef);for (const [key, value] of entries) {this[key] = value;}},};</script>

使用组件

<template><myTable ref="myTabletRef" /></template><script>import myTable from "./myTable.vue";export default {components: { myTable },data() {return {val: 0,};},mounted() {console.log(this.$refs.myTabletRef);// 这里就可以获取到 el-table 组件提供的所有方法},};</script>

2. vue3

封装组件

<template><el-table ref="innerComponentRef" v-bind="$attrs"></el-table></template><script setup>import { ref } from "vue";const innerComponentRef = ref();</script>

使用组件

<template><mytable ref="mytableRef" /></template><script setup>import { onMounted, ref } from "vue";import mytable from "@com/mytable/index.vue";const mytableRef = ref();onMounted(() => {for (const key in mytableRef.value.innerComponentRef) {this[key] = mytableRef.value.innerComponentRef[key];}});</script>
