如何使用 Treeview 修复 Tkinter 代码。我正在尝试让一个表来显示表数据，同时能够切换帧

问：

我是 tkinter 的新手，需要一个表格来显示我的值。我找到了一些有效的表代码，但出现错误。我不能说更多，因为我不明白

这是代码。导致错误的表格内容是从第 127 行到第 183 行。行号可能已关闭，因为我从代码中删除了空格以发布它。 错误：

对不起，如果我发布了太多代码，但上次我被卡住了，很多人因为没有发布所有代码而生我的气。主要部分在bottem。一开始，我定义了工作正常的更改帧，然后我将数据存储在文本文件中，而 bottem 是出现错误的第二个帧。我不确定某些代码是如何工作的，因为我使用示例来创建它。该表应该可以工作，因为我在单独的 python 文件中对其进行了测试。我还测试了第一帧，它工作正常。
