用python写一个ttk.Treeview里放入一个class Ui_MainWindow(object):得代码

好的，这是用Python写一个ttk.Treeview里放入一个class Ui_MainWindow(object)的示例代码：

import tkinter as tk
from tkinter import ttk

class Ui_MainWindow(object):
    def __init__(self):
        self.window = tk.Tk()
        self.tree = ttk.Treeview(self.window)
        self.tree.pack()
        
        self.tree['columns'] = ('name', 'age', 'gender')
        self.tree.column('#0', width=0, stretch=tk.NO)
        self.tree.column('name', anchor=tk.CENTER, width=100)
        self.tree.column('age', anchor=tk.CENTER, width=100)
        self.tree.column('gender', anchor=tk.CENTER, width=100)
        
        self.tree.heading('#0', text='', anchor=tk.CENTER)
        self.tree.heading('name', text='Name', anchor=tk.CENTER)
        self.tree.heading('age', text='Age', anchor=tk.CENTER)
        self.tree.heading('gender', text='Gender', anchor=tk.CENTER)
        
        self.tree.insert('', 'end', text='1', values=('Tom', '18', 'Male'))
        self.tree.insert('', 'end', text='2', values=('Jerry', '20', 'Female'))
        self.tree.insert('', 'end', text='3', values=('Jack', '22', 'Male'))
        
if __name__ == '__main__':
    ui = Ui_MainWindow()
    ui.window.mainloop()
