add demos

[a-teammate]

Hey @ir4y
when testing out the lib I created two ellies:
List Sorting (including some modifications in order to make it look a bit more like a list): https://ellie-app.com/bbmzpJtgNTYa1
Table (unmodified): https://ellie-app.com/bbmBK5w3ZLLa1

In case you want to add those links somewhere, otherwise maybe people will still find it through this issue.
Cheers and thanks for your lib :)

Hi @a-teammate

Thank you for creating samples on https://ellie-app.com.
Could you please create a pull request with README update?
I think it'll be fair to keep you as an author of these changes.
