# Example of how to hide rows and columns in XlsxWriter. In order to
# hide rows without setting each one, (of approximately 1 million rows),
# Excel uses an optimisation to hide all rows that don't have data.

# Write some data.

# Hide all rows without data.

# Set the height of empty rows that we do want to display even if it is
# the default height.
for row in range(1, 7):
    worksheet.set_row(row, 15)

# Columns can be hidden explicitly. This doesn't increase the file size..
