To implement a sortable dataGrid, i've seen beehive supports with ui and
model. I guess the sorting algo needs to be implemented by the user
(implement a sort method for some actions).
How beehive solves the problem of showing the page with the actual item in
the list after sorting or filtering? e.g showing page 3/3, append
filter, ->> showing page 2/2. Or after sorting, show the page with the last
marked (however) item.
