Align the SPEED column

[BillyDonahue]

The primary change is to get the SPEED column to line its decimal points up.
Part of doing that was breaking down the SIMPLE_COLUMN macro into pure C++.

I think your for loops need reference indexes so I fixed those too.
Otherwise you copy each element into a loop variable unnecessarily.
