我想知道如何调整ttk.Treeview列中的文本。下面是我的意思的一个例子。请注意日期和数字之间的位置不正确。我认为这和间距有关，但我可能错了。

编辑：用Python 3编写。#! coding=utf-8

import pickle

import matplotlib.pyplot as plt

import tkinter as tk

from tkinter import ttk

# Create Example

root = tk.Tk()

root.minsize(200,300)

tree = ttk.Treeview(root,columns=("date"))

tree.heading("#0" , text='Sample', anchor=tk.W)

tree.column("#0", stretch=0)

tree.heading("date", text='Date', anchor=tk.E)

tree.column("date", stretch=0)

ABC = ["A","B","C","D","E"]

dates = ["3.4.2013", "14.10.400", "24.12.1234", "1.10.1", "14.7.123"]

tree.insert("",iid="1", index="end",text="No Format")

for i in range(len(ABC)):

dates2 = dates[i].split(".")

date = "{:<2}.{:<2}.{:<4}".format(dates2[0],dates2[1],dates2[2])

tree.insert("1",iid="1"+str(i), index="end",text=ABC[i], value=[dates[i]])

tree.see("14")

tree.insert("",iid="2", index="end",text="With Format")

for i in range(len(ABC)):

dates2 = dates[i].split(".")

date = "{:>2}.{:>2}.{:>4}".format(dates2[0],dates2[1],dates2[2])

tree.insert("2",iid="2"+str(i), index="end",text=ABC[i], value=[date])

tree.see("24")

tree.pack(expand=True,fill=tk.BOTH)

root.mainloop()
