Header tooltips #295
Description
Naming columns can be easy, and can be difficult sometimes. Even when it is easy, we often need to explain a little more about the data in a certain column without having to clutter the page / table with too much text.

Something like this:
Or maybe just hovering over a column name shows the optional tooltip:
Thanks!
