如何使用tkinter正确显示熊猫数据帧？

import tkinter as tk
from tkinter import ttk
import pandas as pd

window = tk.Tk()
window.title("显示熊猫数据帧")

frame = ttk.Frame(window)
frame.pack(pady=10)

data = {'姓名': ['张三', '李四', '王五'],
        '年龄': [25, 30, 35],
        '性别': ['男', '女', '男']}
df = pd.DataFrame(data)

tree = ttk.Treeview(frame, columns=list(df.columns), show='headings')
for column in df.columns:
    tree.heading(column, text=column)
tree.pack(side='left', fill='y')

scrollbar = ttk.Scrollbar(frame, orient='vertical', command=tree.yview)
scrollbar.pack(side='right', fill='y')
tree.configure(yscrollcommand=scrollbar.set)

for index, row in df.iterrows():
    tree.insert('', 'end', values=list(row))

window.mainloop()
