Add the text renderer to the view so events get routed to it properly.

You can add more than one.

The text renderer encapsulates an attributed string and a frame.

The attributed string in this case is set by setAttributedString:
|

which is configured by the table view delegate. The frame needs to be
|
|
set before it can be drawn, we do that in drawRect: below.
