Check the render method of `Body`. See https://reactjs.org/link/warning-keys for more information.

问题分析

Check the render method of 'Body'.，Table 组件没有加 rowKey 导致

问题解决

// 为 rowKey 属性赋值
<Table dataSource={data} rowKey={(record) => record.id}>
// ...
</Table>

 问题消失 nice～

附：如果id不能保证唯一，可以使用index， 或者随机数 // 注意更新时不可用

# index 使用方式
index.toString()
