Sort source, transformed, and target repository metadata on some bundle's detail page nicely

I'd be nice to have the three different sets of metadata associated with a bundle, with identical keys on one line.

Example:

key                      || source metadata | transformed metadata | target repository metadata
-------------------------||-----------------|----------------------|---------------------------
dc.title                 || HELLO           | Hello                | Hello world
bla.uninteresting        || dkfjdkj         |                      | 
internal.dda.identifier  ||                 | somewhere@@foo       | somewhere@@foo
ssoar.identifier.classoz ||                 |                      | 20059
