React16 ant table如何捕捉滚动条到达底部? 虚拟DOM转化真实DOM

用的是React16的Hook版本

let usertable = useRef();
let tablediv = useRef();

<div
onScrollCapture={() => onScrollHandle()}
ref={c => tablediv = c}

<Table
columns={columns}
dataSource={data}
pagination={ false }
bordered
size='small'
scroll={{ y: 476 }}
ref={c => usertable = c}
/>
</div>

const onScrollHandle = function() {
ReactDOM.findDOMNode(usertable);
}

使用ReactDOM.findDOMNode捕捉usertable会报错。
Error: Argument appears to not be a ReactComponent. Keys: current
捕捉tablediv得到的scrollTop,clientHeight,scrollHeight永远都是固定的值,不会跟随滑动而改变。
