有没有一种方法可以从Tkinter中的条目表中逐行获取数据？

import tkinter as tk
from tkinter import ttk

def get_data():
    selected_items = []
    for i in range(len(tree.selection())):
        item = tree.selection()[i]
        values = tree.item(item, 'values')
        selected_items.append(values)
    print(selected_items)

root = tk.Tk()

# 创建条目表
tree = ttk.Treeview(root)
tree['columns'] = ('Column 1', 'Column 2', 'Column 3')

# 添加列标题
tree.heading('#0', text='Item')
tree.heading('Column 1', text='Column 1')
tree.heading('Column 2', text='Column 2')
tree.heading('Column 3', text='Column 3')

# 添加数据
tree.insert('', 'end', text='Item 1', values=('Value 1.1', 'Value 1.2', 'Value 1.3'))
tree.insert('', 'end', text='Item 2', values=('Value 2.1', 'Value 2.2', 'Value 2.3'))
tree.insert('', 'end', text='Item 3', values=('Value 3.1', 'Value 3.2', 'Value 3.3'))

tree.pack()

# 添加获取数据的按钮
button = tk.Button(root, text='Get Data', command=get_data)
button.pack()

root.mainloop()
