Another try; had a bad hour this morning, too many typos. 
This comes closer to what you want, but not exactly. 
You might try to manually call format.df which is implicitly 
called in latex, and massage that.
Again, I do not know if this is easier with xtable.

If you want to post latex samples, it is not really
necessary to include it in Sweave. The example
below works fine for testing.
