Kivy: making a table widget - python-3.x

Question

I am working with kivy in a table widget using GridLayout and ScrollView. This is what i have:
https://github.com/Skucul/listwidget
there is a better way to implement it? What about RecicleView?

Answer 1

I got very nice results with RecycleView and KivyMD, which has list elements with Icons and images, etc.
I saw your other repositories too, eg Datepicker and Timepicker, there are similar, there are very similar Widgets in KivyMD, maybe you would consider to use them or even better, enhance them.
