我可以让tkinter的树视图从右边开始吗？

import tkinter as tk
from tkinter import ttk

root = tk.Tk()

# 创建Treeview对象
tree = ttk.Treeview(root)

# 设置Treeview的列属性
tree.column("#0", anchor="e")
tree.column("column1", anchor="e")
tree.column("column2", anchor="e")

# 设置Treeview的列标题
tree.heading("#0", text="Column 0", anchor="e")
tree.heading("column1", text="Column 1", anchor="e")
tree.heading("column2", text="Column 2", anchor="e")

# 添加树视图的数据
tree.insert("", "end", text="Item 1", values=("Value 1", "Value 2"))
tree.insert("", "end", text="Item 2", values=("Value 3", "Value 4"))

# 显示树视图
tree.pack()

root.mainloop()
