Didn't even realize that. I made a lot of changes to that line trying to get it to work. I started off with:
A(value, _href=db.shipper(row.shipper).url + value)), Which I got from http://stackoverflow.com/questions/10389775/how-can-i-make-sqltable-results-link-to-outside-pages. But was being told, "AttributeError: 'NoneType' object has no attribute 'url' ". So messing around with the syntax I ended up with what you see above. Interestingly, it worked, i.e. didn't produce an error, but did produce the issue above. I changed the href code as you suggested, and was still getting the link problem. I had entered the carrier.url as "www.bing.com/search?q=" instead of "http://www.bing.com/search?q=";. Now, having made both changes, it works like a charm! Thank You!
