[XeTeX] Beginning user with questions

[Ruth Robbins]

Hi,
i'm using xetex to typset a grammar of a tonal languge. At the moment  
I'm trying to figure out how to properly set up a simple table that  
has no lines (horizontal or verticle). I've been going to various  
resources online and it's still not working.

Also, my typeset document has been consistently ending after the first  
chapter even though end document doesn't come until the end of  
everything.
what might I be missing?  Is there something written on making tables  
in Xetex/XeLatex?
