In case it’s helpful, as someone who doesn't know ruby, it's hard to understand. Not too readable. Split.last.ljust I just barely understood (left-justify the last match), but I have no idea what the next part is even trying to accomplish.

It's a cool script though.

That's the author's oneliner. I don't know what that code is for either, which is part of I rewrote it in the second set of examples.

It's normal for a oneliner to be somewhat inscrutable though, since they're often extremely dependent on their inputs. Like if it's important to fetch the 3rd, 5th, and 7th column--why? You can't tell without the input.
