Rotated Table Column Headers

Perhaps not a huge problem for two columns, but if you had 20 that would be very hard to navigate and a poor use of space. A better use of space is to rotate the headers so that the column width can be much narrower.

Rotating 90-degrees is too far though. It makes it hard to read.

Interestingly, we get just about the same amount of space saving if we rotate the headers 45 degrees instead, and they are much easier to read.
