Solution: ProTable selects thousands of pieces of data at a time and selects them in pages, resulting in page lag.

1. Install the plug-in virtuallist-antd

npm install --save virtuallist-antd

2. Set the components attribute of the Protable component in the page.

// demo.tsx
import { useMemo } from 'react';
import { VList } from 'virtuallist-antd';

const VComponents = useMemo(() => {
    // 使用VList 即可有虚拟列表的效果
    return VList({
      height: 400, // 此值和scrollY值相同. 必传. (required).
      resetTopWhenDataChange: false, // 默认为true. 是否数据变更后重置滚动条.
    });
}, []);

<ProTable
   ... // 省略code
   scroll={x: 1200, y: 400}
   rowSelection={
   
   { 
    onChange: changeSelect,
    preserveSelectedRowKeys: true, // 跨页保留之前勾选项 
   }}
  components={VComponents}
/>
