如何在TabeedPanel中使用GridLayout在python中使用kivy

from kivy.app import App
from kivy.uix.tabbedpanel import TabbedPanel
from kivy.uix.gridlayout import GridLayout
from kivy.uix.button import Button

class MyTabbedPanel(TabbedPanel):
    def __init__(self, **kwargs):
        super(MyTabbedPanel, self).__init__(**kwargs)
        
        # 创建选项卡
        tab1 = TabbedPanel(tab_text='Tab 1')
        tab2 = TabbedPanel(tab_text='Tab 2')
        
        # 创建GridLayout布局
        layout1 = GridLayout(cols=2)
        layout2 = GridLayout(cols=3)
        
        # 向布局中添加组件
        layout1.add_widget(Button(text='Button 1'))
        layout1.add_widget(Button(text='Button 2'))
        layout2.add_widget(Button(text='Button 3'))
        layout2.add_widget(Button(text='Button 4'))
        layout2.add_widget(Button(text='Button 5'))
        
        # 将布局添加到选项卡中
        tab1.add_widget(layout1)
        tab2.add_widget(layout2)
        
        # 将选项卡添加到TabbedPanel中
        self.add_widget(tab1)
        self.add_widget(tab2)

class MyApp(App):
    def build(self):
        return MyTabbedPanel()

if __name__ == '__main__':
    MyApp().run()
