react函数式父组件获取子组件dom

1.子组件使用forwardRef

import React, { forwardRef, useState } from 'react';
function SonTable (props, tableRef) {
  const { table_config, data } = props;
  return <div ref={tableRef}></div>
}
export default forwardRef(FundTable);

2.父组件

import React, { useEffect, useRef } from 'react';
import SonTable from '../components/SonTable';
export default function Home() {
   const sonRef = useRef();
  useEffect(() => {
    console.log(sonRef )
  }, []);
  return (
    <div>
      <SonTable ref={sonRef } props={{}}/>
    </div>
  )
}
