如何在SQLServer的SQLAlchemy中定义ID列的起始值？

from sqlalchemy import create_engine, Column, Integer
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker

engine = create_engine('mssql+pyodbc://username:password@server/database')
Session = sessionmaker(bind=engine)
session = Session()

Base = declarative_base()

class MyTable(Base):
    __tablename__ = 'my_table'
    id = Column(Integer, primary_key=True, autoincrement=True, server_default='1')
    # 其他列的定义...

Base.metadata.create_all(engine)
