在tkinter中使用网格时如何创建滚动条？

import tkinter as tk
from tkinter import ttk

root = tk.Tk()
scroll_area = ttk.Frame(root)
scroll_area.grid(column=0, row=0, sticky='nsew')

canvas = tk.Canvas(scroll_area)
scrollbar = ttk.Scrollbar(scroll_area, orient='vertical', command=canvas.yview)
canvas.configure(yscrollcommand=scrollbar.set)

canvas.grid(column=0, row=0, sticky='nsew')
scrollbar.grid(column=1, row=0, sticky='ns')

inner_frame = ttk.Frame(canvas)
canvas.create_window((0, 0), window=inner_frame, anchor='nw')

scroll_area.columnconfigure(0, weight=1)
scroll_area.rowconfigure(0, weight=1)

# 在inner_frame中添加需要滚动的内容
# 例如：添加标签
label1 = ttk.Label(inner_frame, text='Label 1')
label1.grid(column=0, row=0)

# 更新Canvas的滚动区域
inner_frame.update_idletasks()
canvas.configure(scrollregion=canvas.bbox('all'))

# 绑定Canvas的滚动事件
canvas.bind('<Configure>', lambda event: canvas.configure(scrollregion=canvas.bbox('all')))

root.mainloop()
