See :doc:`on_demand`.:param ragged_rows:The default of ``False`` means all rows are padded out with empty cells sothat all rows have the same size as found in:attr:`~xlrd.sheet.Sheet.ncols`.``True`` means that there are no empty cells at the ends of rows.This can result in substantial memory savings if rows are of widelyvarying sizes.
