Add example for editable table about quasar

It works until it doesn't. You haven't bumped into issues but you will as soon as you configure QTable more. You need to supply it.

Adaptation to Quasar 1 is easy, just change :rows to :columns in the first line.

Hi,

There's also the "Popup editing" section, but added a simple one with QInput.
Don't forget to add props to your QTd: <q-td :props="props">

Why do Ineed to propagate the props?
I read somewhere that it is no longer necessary. Maybe that information was wrong, but it definitely works without it.

BTW, I referenced the popup-section in the description, because I personally don't like the usage. It needs too many mouse clicks if I want to edit multiple cells. In the above example I can use the tab key to move to the next cell.
