Hi,
yes, that's a good suggestion, VisualData!
For just a few items/tables, a hardcoded switch with the Template Tag functions should be the easiest. Custom Fields should give you more flexbility if you want this for many items/tables or if you want this to be configurable by the user/editor who works on the pages.
In both cases however, you will have to do a little bit of PHP programming.

Tobias
