如何删除 Tkinter 应用程序中的空列

Question

从DB以表格形式输出数据时，会出现一个空列，占用大量空间。

在此输入图片描述

我想删除此栏，但不知道如何删除。这是我的代码：{

tables = []

edit_entry = None

    button_hide.pack(side="top", pady=10, padx=10)

    root.mainloop()

}

我尝试使用 columns = [desc[0] for desc incursor.description if desc[0] not in ['rowid']] 删除它，但没有帮助

Answer 1

它是树列，可以通过在创建

show="headings"

小部件时设置

Treeview

来删除：

...
tree = ttk.Treeview(table_frame, xscrollcommand=scrollbar_x.set,
                    yscrollcommand=scrollbar_y.set, show="headings")
...
