Multi / Sticky Data-Grid Sorting

[johnorford]

I am looking for a feature like this,

https://vaadin.com/elements/-/element/vaadin-grid#demos

where I click on different sorts, and the sorts sticks, which allow me to sort by multiple criteria - or - something like group sorting, e.g.

Dept Employee

Mngt Abe
Mngt Jerry
Fin Barry
Fin Chad

etc.

Before I consider diving into the code, I was wondering whether anyone can give me any pointers - what to look out for etc.

Thanks.
