+ * An example of how to hide rows and columns using the libxlsxwriter
+ * library.
+ *
+ * In order to hide rows without setting each one, (of approximately 1 million
+ * rows), Excel uses an optimization to hide all rows that don't have data. In
+ * Libxlsxwriter we replicate that using the worksheet_set_default_row()
+ * function.
