feature request: htmlwidget ui wrapper for pivot_table()

A feature request or wish for a htmlwidget ui wrapper to the pivot_table() fcn, similar to what shows up in this screenshot:

Or is it already available somewhere else outside of this package? Does the screenshot use https://github.com/rte-antares-rpackage/manipulateWidget for the UI?

Allowing for output also from rmarkdown (htmlwidget output standalone w data embedded and no dep on shiny runtime).

Also, hat off for awesome work with porting those Excel fcns!

I will look into this.
