how to add multiple tables in single nopcommerce plugin - asp.net-mvc-5

Question

I want to create a plugin in nopcommerce which has many options for weight shipping and i need 2 tables,one for shipping details and another one for neighboring province which has many-to-many relation with province table.
how can i create two tables in one plugin?
all documentations explain single table in single plugin.
