/*
|
|
* 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.
