Python 更改单元格后，openpyxl会破坏文件格式

我的.xlsx格式（UPO模板）有一些奇怪的格式

模板如下所示：

更改任何单元格中的值后，格式将被破坏，图像将消失：

更改单元格的代码如下所示：

wb2 = load_workbook('template.xlsx')
ws2 = wb2.active

ws2['A1'] = user.name

wb2.save('template.xlsx')

标准的东西，但有些不对劲。我应该使用另一个模块而不是openpyxl吗？

这是一个已知的错误，在openpyxl的BitBucket问题列表中标记为已解决。但是，它仍然不起作用，您必须使用kseehart/db2053建议的补丁

我在这里为您复制了补丁：
（免责声明：这不是我创建的，它是由kseehart/db2053作为解决方案提出的）

图像不支持读取。除了图像，当你说格式被破坏时，你的意思是单元格大小被更改了？
