How to dynamically create tables with SQLAlchemy?

Question

Python

Flask based application. I use SQLAlchemy to interact with the database. There is a group of application database tables that are hardcoded in the code. I use Flask-Migrate to create and migrate them. So far everything is more or less satisfactory.
It is necessary to dynamically create tables in the database and minimally work with them - create, delete. You also need a minimum of work with columns - add a column, delete a column.
It also doesn't need the table to be included in the shared migration created with Flask-Migrate.
I have a dynamically generated class that describes a future table, which is generated by a special function. What tool or method can be used to solve this problem?
