What problem does this feature solve?

I need to show user some information when onRowMouseEnter fired! This could be a message or record data.

需要在 onRowMouseEnter 事件触发时显示一个类似于 Popover 的消息框，这个消息框给出该行的数据或者其它信息。

What does the proposed API look like?

  const handleMouseEnter = (record, index) => {
    <Popover content={record.msg}/>
  }
