BeatifulSoups matching is for any tag with a matching attribute, not
tags that only match that attribute. That's why you're getting tags
with other attributes.

However, you can use a callable as the tag argument to check for what
you want:

def findtagswithly(name, attr):
    return (lambda tag: tag.name == name and
                        len(tag.attrs) == 1 and
                        tag.attrs[0][0] == attr)

...

    cells = table.fetch(findtagswithonly('a', 'bgcolor'))


Or, because I wrote it to check out:

def findtagswithoneattrib(name):
    return lambda tag: tag.name == name and len(tag.attrs) == 1

...
   cells = table.fetch(findtagswithoneattrib('a', {bgcolor: re.compile('.+)}))

I'm not sure why you're getting tags without attributes. If the above
code does that, post some sample data along with the code.
