This doesn't add up. CSS grid, flex box, etc all do the "holy grail" layout with a couple lines. The tables mess that was early www was and remains an absolute mess of markdown to maintain for layout. Semantics and accessibility are practically out the window with table. HCI dictates how humans use interfaces and with that comes many defacto reasons why a plain text page does not solve the problems users want to solve. Do you not think websites test into the optimal performing layouts and content distribution? If it worked better, we'd all be using it (it doesn't).
