When moving from print design to web design, little by little, designers had to accept to abandoned tables (and "points", and in general, the idea that their design should look "perfect" and "the same" in all contexts). It took them quiet a lot of time to accept it (I'd say 10 years or so... )
Tables/Array of questions were perfect for paper surveys (easy to print, quick to fill, etc).
Now that surveys should be run on many different devices/screens with many different sizes, resolutions, pixel density (retina...), survey designers should accept to abandoned arrays/tables of question. I bet it will take quiet a lot of time too.
