我想按原样从数据库加载表，但我不知道表结构。如果我跑

from pydal import DAL
db = DAL('mysql://phpmyadmin:123@localhost/my_db', lazy_tables=True)
t = db.table1

我得到错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/andrey/python/folder/lib/python3.8/site-packages/pydal/base.py", line 790, in __getattr__
    return BasicStorage.__getattribute__(self, key)

如果我使用db.define_table('table1')

from pydal import DAL
db = DAL('mysql://phpmyadmin:123@localhost/my_db', lazy_tables=True)
db.define_table('table1')
t = db.table1

我收到另一个错误

Traceback (most recent call last):
