At a guess, and I stipulate that because I am just learning about all
this, I'd say that's because DictReader returns a dictionary for each
row retrieved...  It DOES take the first row and make those the dict
keys, but after that, it just returns a Dict for each rows and
dictionaries seem to be randomly ordered.

It may not be that great if you're doing  something that needs order,
but all he's doing is pulling arbitrary columns from a file and
printing as a table, so that works great in this case...

It was quite interesting messing around with that yesterday.  I saw
the question, and it looked interesting, so I went and learned and
applied ;-)  I'm rather smugly satisfied with myself ...

Cheers,

Jeff
