This last example is really awesome.
But this is hard to implement in an user interactive app, because a bit far from a full editable dataframe in an “Excel” fashion, to record user’s inputs…
I try to create an app with an optimization function, variables and constraints: I don’t know how to input the various parameters of my bunch of constraints. That’s why I was also thinking of an editable table.
Maybe instead of this editable table, what could be the best way to populate e.g. a 4x4 table for the app user ?
