[Vuejs]-Vue.js How to bind an element of the data array to a child components property?

I found one possible solution:
When you pass an object down to the child component, then it is passed by-reference. That means when the child component updates the properties of this object, then the changes are immideately visible in the parants data.

So I simply pass down the whole row to each editable-cell. Then it can update its property/value in that row.
