Table domains are not supported in the work center. These specifications have a lookup defined on the classspec table to control which attributes need to be displayed. We couldn't handle that with the different frameworks between classic and work center so we don't display those table domains.
In 8.11 with the new Maximo Mobile (which is also available in the web) SR experience, we do support table domains using a new process we've developed but it breaks each record down into value & description. The description field is determined by looking to see if a couple of fields exists (starting with the obvious description) but otherwise will only display the value (which we get from the table attribute defined on the specification).
