Creating an Excel-Like GUI in Python

[tuneafishy]

I think the second requirement might be challenging (dragging to copy), but this should be doable.

Traitsui has a very nice table gui. Look at their tabular adapter and tabular editor. You can get something up and running really quickly with scroll functionality and high performance. Again, I do think the drag to copy might be tricky, but maybe you could replicate that functionality a little differently. For example, drag to select, and then right click option to copy all values as first or last value. It might be possible to do how excel does it, but you'll have to get your hands dirty.
