make data tables horizontally scrollable if needed

Summary:
Changelog: most data tables allow for horizontal scrolling now if they run out of space

This diff introduces support for horizontal scrolling in datatables. Originally thought about making this a view option, but doing automatically works actually quite fine. By default the columns resize as they did, but if either a column is made bigger or the window is so small no space is left, a horizontal scrollbar can be used.

This adresses several usability issues reported in GH / workplace
