In the bottom right corner of the CodePen example, there should be a button that says Fork. Click it. This will make a copy of the code that you can save to your CodePen account.
While anyone can edit or fork a CodePen, you can’t save and share your work without creating a CodePen account. It’s easy and free. The button to do this is in the upper right corner of the CodePen window.
Not terribly original and freely borrowing from the demo:

I am thinking there is a more readable way for me to arrange this information in the table than what I have done...
