Better supporting data-oriented tables

Created by: khawkins98

Roman Laskowski (Thornton research group) is working to port VarSt and has encountered some use cases whose solutions will likely be of use to others:

1. How to make tables not 100% wide
2. Thinner padding on data tables
3. Stretch images out of their normal aspect ratio

These aren't surprising issues for data-oriented tables.

Spirit of solution is to create individual overrides for the above (not change default behaviour) and to create a new style for table.data-table that would implement this more compact look and is a placeholder for further functionality/tweaks to be added.
