Bugged layout in iOS

I went to go train my client on how to use FB backend and we saw this on both their iPad and iPhone. The browser didn't matter Safari, Chrome, Firefox all showed the same thing. Did some research and apparently iOS parses css tables differently and causes this, and different browsers don't help because Apple locks down their devices so it doesn't matter what browser you use, it's all the same webkit.

I ended up buying an iPad so I can see and fix frontend issues the iOS browser causes, but it would be great if you guys could fix the backend so we aren't all having to fix it individually for our clients!
