Feature request: ability to log tables

A picture is worth a thousand words ;-) http://jdem.cz/ha2m5

Start by reviewing the repository's existing logging entry points and the linked screenshot to determine what “log tables” should mean. Compare the current logger output with the FireLogger console behavior; done should be defined as table data being accepted and rendered as a table, but the issue does not identify files, tests, or exact input and output requirements.
