请教要如何解决ttk的Treeview列宽和边框线闭合

import tkinter as tk
import tkinter.ttk as ttk

root = tk.Tk()
root.title(‘text’)
root.geometry(‘800x400’)
frame = tk.LabelFrame(root, text=’分析区’, font=(‘宋体’, 10), fg=’red’, labelanchor=’n’, bd=1, height=140, width=600,
relief=’groove’)
frame.pack(side=’left’, pady=2, padx=2)
frame.pack_propagate(0)
fram1 = tk.Frame(frame, width=20, height=20)
fram1.pack(side=’left’)

mark = [str(i) for i in range(1, 21)]
table = ttk.Treeview(frame, columns=mark, height=5, style=’Treeview’, show=’headings’)

for j in range(len(mark)):
table.heading(column=mark[j], text=mark[j], anchor=’center’)
table.column(j, minwidth=0, width=28, anchor=’center’, stretch=tk.NO)
table.pack()

root.mainloop()

最佳答案

Column identifiers take any of the following forms:

A symbolic name from the list of -columns.
An integer n, specifying the nth data column.
A string of the form #n, where n is an integer, specifying the nth display column.

column #0 always refers to the tree column.

The cid for method Column should be the mark[j], j+1 or f'#{j+1}', not j.

It means that you didn’t set the width for column '20', and the default width is 200 pixels, so the treeview will exceed the visible range of FRAME.

for j in range(len(mark)):
    table.heading(column=mark[j], text=mark[j], anchor='center')
    table.column(mark[j], minwidth=0, width=28, anchor='center', stretch=tk.NO)

Of course, you can remove the option `width=600` from the `frame`, also the statement `frame.pack_propagate(0)`.
