Is there a widget with these functionalities?:
No currently there is no such widget. Some things are just going to have to be done in ArcMap.
I had seen a tool on github a while back and didn't know if someone had made a widget similar to it.
Ideally editing would be standard functionality built in like Flex Viewer.
In beta now but readOnly:false will be great. I played around with the dgrid and its still a little sketchy with large tables.
Is there a widget like this now?
While the attribute table in the map viewer is now editable, the web app builder attribute table is not yet editable.
