I tried the new clappr-zepto:0.0.5 version on clappr and this appears  I don't know why `f` is undefined in there when trying to create a table. What I did was: 1. Update clappr package.json (clappr-zepto to 0.0.5) 2. npm install 3. npm run release 4. Try it in the browser and fails (I don't know if there is something wrong in the steps I did)
