Answer: 
The simplest difference is that a wireway is a raceway and cable tray is not.

Here are the definitions of each item from the National Fire Protection Agency(NFPA) 70, National Electric Code (NEC) 2008:

NEC 376.2 Metal Wireways. Sheet metal troughs with hinged or removable covers for housing and protecting electrical wires and cable and in which conductors are laid in place after the wireway has been installed as a complete system.

NEC 392.2 Cable Tray System. A unit or assembly of units or sections and associated fittings forming a structural system used to securely fasten or support cables and raceways.

NEC 392.3 Uses Permitted. Cable tray shall be permitted to be used as a support system for service conductors, feeders, branch circuits, communications circuits, control circuits, and signaling circuits.
