I'm going to take a contrarian view here. Code formatting is amazing in a corporate environment where nobody truly cares about their code -- it's just a means to get a paycheck. It's also great for beginners to a language who are still trying to get a handle of the syntax.
But where you are nearly the sole owner of a small library and you are crafting that library to be beautiful and understandable... there is something pleasurable about structuring concepts so you have each on a single line, or creating similar functions so the concepts are structured by column.
I know not everyone will hold this view and that is fine, but when you are writing your own hobby library in your favorite language for your own purposes I recommend you try it out.
