Okay, somehow the columns of numbers didn't look very useful on my 
screen to me, and I wanted to convert this to UL (and straighten out the 
logic), so that's why I made this change.   I asked around internally to 
see which people would care about the format change and didn't find 
anyone specific.  Now I know!

Let me rework this to use UL but keep the table.

I'll withdraw this change for now.

Thank you for the quick feedback.
