EditableGrid is an open source Javascript library aimed at turning HTML tables into advanced editable components. It focuses on simplicity: only a few lines of code are required to get your first table up and running.
I can only find version 2.0.1 on github. Where did you find 3.0? And the github version does not work with IE 11 although the same online demo as including in the tar file does.
Is 2.0.1 still the latest version? It seems like it was built long ago...
Also, has the API changed? I'm trying to create a simple example using the latest code (supposedly 3.0), but I am getting errors. I posted a question on StackOverflow: http://stackoverflow.com/questions/25881803/editablegrid-fails-to-load-inline-json-data
