I need to create some pivot table from a data sheet in excel file. I found that openpyxl have add pivot package from ver. 2.5: https://openpyxl.readthedocs.io/en/2.5/api/openpyxl.pivot.html
But it's hard to understand how to use this package. May you add some more example source code of using pivot package to add pivot to excel file.
