【问题描述】：
我正在开发一个 GUI 应用程序，其中一些数据将从数据库中获取并显示在树形视图中。但问题是我的树形视图有大约 20 列，这太多了。我的意思是整个应用程序无法适应我的屏幕。
所以我最初只想显示 2-3 列，并且我希望通过滚动条可以看到其余列。
我已经使用“displaycolumns”选项来显示前 3 列，并且我也创建了滚动条，但我无法弄清楚如何通过滚动条使其余列可见。
以下是我的代码，我删除了按钮方法和数据库功能以简化它
将 tkinter 导入为 tk 从 tkinter 导入 ttk 导入openpyxl 从 tkinter 导入文件对话框 将 tkinter.font 导入为 tkFont

我的问题是我必须在这里添加大约 20 列但我只想一次显示 3-4 列其余列只能通过滚动条可见，我的行滚动条工作正常但我不知道如何为列做到这一点
谢谢
【问题讨论】：
-
创建两个树视图 - 一个具有始终可见的列，第二个具有滚动条。
-
对不起，我没听懂。如果我创建一个所有列都可见的树视图，它将不适合
