Force table format and crosstab to excel

[danilo-css]

Thank you so much for this package, I've been looking for something like this for ages. Some features from Tableau I would like to see:

1 - Force table format, as I very much like it for basic data exploration. 2 - Crosstab to excel, to download the data being shown in the viz to Excel, CSV or something.

Also, reinforcing #11, support for streamlit would very much be appreciated and would increase the potential of this package by a lot.
