But like swa said, why would you want to? Unless you're in the Counterweight Group. The large number of people using tables for layout are counterbalanced by a small number who have been so terrorized by the Don't Use Tables directive that they won't use tables even when they are clearly warranted.
And that's speaking as someone who has only just exercised heroic self-control by taking a text with three parallel translations and not formatting it as a three-columned table. (Two, and it would have been a table. Three, and width constraints won out.)
