:param on_demand:

Governs whether sheets are all loaded initially or when demanded

by the caller. See :doc:`on_demand`.

:param ragged_rows:

The default of ``False`` means all rows are padded out with empty cells so

that all rows have the same size as found in

:attr:`~`.

``True`` means that there are no empty cells at the ends of rows.

This can result in substantial memory savings if rows are of widely

varying sizes. See also the :meth:`~_len` method.

:returns: An instance of the :class:`~` class.
