Quite some time ago, there was a burninate request for table on MSE. It was closed as "off-topic," but never migrated here. The tag's wiki rather strongly (i.e. in ALL CAPS) discourages the use of the tag, but that doesn't seem to be stopping people.
The tag is highly ambiguous, being used in at least three different senses just in the first page of questions I looked at (namely database tables, HTML tables, and R data tables). I don't really think it's helpful in its current form.
If we really don't want people to use this tag, we should properly burninate it. And if we do, then we should nix the wiki notice.
(Also, there are ~23k~23k 2,112 Open questions in that tag, so manual retagging may be... slow)
