Each Input and Output is linked to another transaction, where it makes sense (for example, there is no link if the output hasn't yet been spent).

However, when implementing the same page in AshCoin I originally did this:

I've since hidden the columns to avoid the eyesore. However, the functionality to display those transactions should be implemented as an enhancement.
