Instead of defining a global function showCell and hardcoding the
onclick handler in the html for every cell you could iterate over the
elements in question (in this case that would be the anchors that have
the CSS class clickable):

   html selector
      add: 'a.clickable';
      do: [ :each | each element on: 'click' do: (html updater ...) ]

> Render Time (with 1 callback) : 6 ms
> File Size (with 100 callbacks): 20736
> File Size (with 1 callback): 8611

Good ;-)
