but...

I think you probably want syntax that's more like:

-> ^(TABLECELL, $cell)

See:
http://www.antlr.org/wiki/display/ANTLR3/Tree+construction

If that doesn't get you going, it might be good to post clarifying:

... are you are writing this *in* a tree grammar, or in a combined grammar
trying to produce a tree?  Also describe what actual errors you are seeing.
