如果需要整个代码文件，以及数据库中的数据，或者有较为复杂的问题，请添加QQ：3095631599（CSDN-山河之书），添加时请备注：CSDN。

本部分将叙述数据导入界面函数（即本专栏第三篇文章中的load_data_choose函数）及其下属界面的制作过程

这部分总共包括十一个界面：导入表格选择界面以及下属的十张表的导入界面

可以实现的功能包括：支持对除账户表格外其他表格进行选择，并进入具体表格数据导入界面，支持导入文件的路径格式合法性检查、路径存在性检查，支持数据批量导入。

接下来将舞台交给代码段，所有的解释都将以注释的形式呈现：

喜闻乐见的运行截图：

 

 

由于本人手中目前没有另外的数据，因此也暂时没有导入数据的具体截图，但是之前试用的时候还是可以用的。

实在是懒得另找数据了，如确有需要请直接联系本人，本人再准备数据进行测试 。
