Current behavior

Lazy loading on DataTable has the ability to load pages of data and each time the page changes a loading flag can be set and an internal "loading" overlay and icon is set.
This is not implemented on DataView, despite documentation stating "Refer to DataTable lazy loading for a sample implementation"

Expected behavior

Be able to set a "loading" prop which displays the internal loading overlay

Minimal reproduction of the problem with instructions

Is it the lazy loading implementation or the lack of loading prop? I see that there is a lazy prop in DataView as well. I'll add a sample to next week's 4.1.2 like the in memory sample of DataTable to provide an example.

Also for Table, we'll add a demo with node.js and a real datasource like mysql to demonstrate lazy page-sort-filter.

@cagataycivici both really. There is no loading prop and there is no implementation of the internal overlay and chosen icon (or component would be nice)
As far as I can tell, it deals with the pagination ok via the event, but no way to visually indicate that something is happening

@mertsincan is on it for 4.1.2, thanks.
