Python 添加到主帧的帧未在Tkinter中显示

我正在尝试使用tkinter创建一个学校应用程序。我需要显示数据库中的详细信息

该应用程序有两个页面“StaffPage”和“StaffDisplayDetails”。我已经创建了这两个页面作为框架，并将它们堆叠起来以显示它们。它工作得很好

但是当我想显示数据库中的数据时，框架没有显示出来

这是我的密码。感谢您的帮助

您发布的代码远远超过了重现问题所需的代码。请看。您的意思是

职员\u window1

？您将

staff\u window1

放在最右侧（

column=150

），可能在窗口的可见区域之外。@acw1668谢谢您，它成功了
