How does pandas save dataframe to sql?

How does pandas to_sql save a dataframe to sql is it by saving the rows in the dataframe as rows in the Table or it saves the dataframe as a whole in a row in the table

In short, each row of the dataframe becomes a row in the table.

If you look at the documentation, they provide an example where they write to a database and then read back from it so you can get a mental model of how it works.
