So now lets make it a problem for all users!

Seriously, I thought this was why you introduced the preview options in the editor. Optimising pages for tablets didn't involve coding multiple versions. It was possible to turn tables into lists using CSS. A simple fact of using a smartphone or tablet is that, unless an admin has optimised a table, there may be some horizontal scrolling involved to read large tables. It's still an easier way to digest information in msot cases than large paragraphs.

People will not stop using tables. In most cases, it is the only way to practically convey such information. So why not just accept that they may look a little squished on a tablet and allow destop users to use their screens to their full potential. Encourage people to use the preview functions on the editor.
