The counter argument is that simple tables are simple. And as silly as that sounds, a typical expository essay might easily include a 2 x 2 'table' to explain some principle (I call them McKenzie tables since every presentation from those guys seemed to include one or more). Or simple columnar data like the current price of the Macbook pro line, or any number of things that are represented easily and efficiently in a simple table. That is why I like Fortin's syntax something like:
| widgets | quality level | cut-off point
| :------- | :----------- | :------------
| frobs | 98% | 90%
| bolts | **65%** | 70%
| splangs | 85% | 80%
Reads easily in text and markdown's easily as well using multimarkdown (my current go to implementation). Use your CSS to style the selectors tbody, thead, and colgroup and you're off to the races.
