Not having the full background about this discussion, I just want to add
that I hope the new changes to the Recline UI that uses SlickGrid will
allow extensive customization of the grid cells.

In my use case, the data is an arbitrary JSON document, not necessarily
from a CSV. So individual fields/columns may need to be rendered
differently. Some may not be editable, others might use an autocomplete
text input, etc.

Thanks,
Salman
