Link to an URL / Website

Hey everyone. 
I have looked at the issue #57 However it does not make any sense to me.

But my questions is: How to have an link to an url into a cell.
So if dubbel-clicked, the link / url is opened into a new tab/browser.

Edit: In other words:"How could I use the colum 'website' in this demo active?

I have no real experience with JS.
Thanks in advance
