docs: Add a ``row`` dict by inserting it into the table.
  
          If ``ensure`` is set, any of the keys of the row are not
          table columns, they will be created automatically.
  
          During column creation, ``types`` will be checked for a key
          matching the name of a column to be created, and the given
          SQLAlchemy column type will be used. Otherwise, the type is
          guessed from the row value, defaulting to a simple unicode
          field.

              table.insert(data)
  
          Returns the inserted row's primary key.
