Putting everything in columns is my thing :) We can do something like that. It should not be so hard to put titles on top and draw some lines, I think, if you set fixed column widths. I'm just not sure if it will be really helpful. What sort of use case do you have in mind (besides git-log --oneline with customizable columns)?
