If you're talking about a transparent bridge, then it
builds the table based on the frames it receives. If
the frame comes in on a certain port, it will
associate that MAC with that port. The destination MAC
is compared to the table so it will know where to
send, but it doesn't use the destination MAC to build
the table.
And as with most everything networking, Cisco has this
information on CCO UniverCD.
