This is what you can do with RSD concerning a post that you believed it was out of the scope of RSD.
Some columns, and some subgrids, respanning of columns, and some column offsets. This gets your table down to a mobile phone. I did a desktop down in RSD 1.5 because I think you would be more familiar with that. There is a bunch of flex positioning to make things organized. If you need to catch up, all the info is in the tutorials.
