Python tkinter frame parent widget 排列列
Python tkinter frame parent widget line up columns
我在框架中放置滚动条，在小部件中放置框架。框架上方有一个标签。上面的标签有三列。带有滚动条的框架有三列。我无法让框架中和框架上方的三列对齐。
我看到并使用了以下两个问题来解决这个问题，但卡住了。
Adding a scrollbar to a group of widgets in Tkinter
Tkinter - Add scrollbar for each LabelFrame
如能提供有关排列列的任何帮助，我们将不胜感激。谢谢。
这是没有排列列的小部件的图片：
Columns don't line up
这是一个 MWE：

两个定义的函数在class里，但我没法让它们排成一行
我通常不会这样解决问题，但您可以通过指定标签宽度来强制对齐。当您动态调整 window 的大小时，问题就会出现——一切都是静态的。但这将解决指定的问题 -- 对齐。
