使用antd tabs组件,当我写官网那样的demo的时候切换tab几乎感受不到什么卡顿。但是真正再内部嵌套了table(antd的Table组件)时切换就非常慢了,tabs标签页面内部是一个10行的Table组件。每次切换差不多有1s的时间才会切换过去。 不知道有没有优化的方式,下面时在chrome中performance面板拿到的两次切换的数据

<!--  -->
<Tabs 
defaultActiveKey="1" 
onChange={this.callback} 
>
    <TabPane tab="全部提交" key="1">
      <SubmitTable dataSource={allMockData}/>
    </TabPane>
    <TabPane tab="我的提交" key="2">
      <SubmitTable dataSource={myMockData}/>
    </TabPane>
</Tabs>
// SubmitTable.jsx
import React, { Component } from 'react';
import { Button, Table, Input, Icon } from "antd";
