1.the code of the login.py is as follows：

import streamlit as st
import streamlit_authenticator as stauth
import yaml
from yaml.loader import  SafeLoader
import main_app

with open('./db/config.yaml',encoding='utf-8') as file:
    config = yaml.load(file, Loader=SafeLoader)

authenticator = stauth.Authenticate(
    config['credentials'],
    config['cookie']['name'],
    config['cookie']['key'],
    config['cookie']['expiry_days'],
    config['preauthorized']
)
name, authentication_status, username = authenticator.login('Login', 'main')
if authentication_status:
    with st.sidebar.container():
        cols1,cols2 = st.columns(2)
        cols1.write('欢迎 *%s*' % (name))
        with cols2.container():
            authenticator.logout('Logout', 'sidebar', key='unique_key')
    main_app.main()
elif authentication_status is False:
    st.error('Username/password is incorrect')
elif authentication_status is None:
    st.warning('Please enter your username and password')

2. the code of main_app.py is as follow: 

import streamlit as st
from st_pages import Page, Section,show_pages, add_page_title
def main():
    show_pages(
        [
            Page("main_app.py",name="主页",icon="🏠"),
            Section(name="表格相关处理技术",icon="🏠"),
            Page("menuPages/table_linked.py", "主从表格",icon="💪"),
            Page("menuPages/second.py", "样例2",icon="💪"),
            Section(name="项目相关",icon="🏠"),
            Page("menuPages/xm.py", "项目",icon="💪"),
            Page("menuPages/tax.py", "税率",icon="💪"),
            # in_section=False用明确申明，该页不属于上面的菜单section子项目
            Page("menuPages/test.py",name="最后页面",icon="🏠",in_section=False),
        ]
    )    
if __name__ == '__main__':
    main()
    pass
