latex: colortbl + pdfsync

I just had a frustrating experience.  I was typesetting a table in latex for my LPAR paper.  I was using the colortbl package to add colors.  Strangely, if I used the usual lcr column types, it worked fine.  If I tried to set the column width manually however, the cell ended up taking up the entire page.  After a bunch of fiddling, I found that when I commented out \usepackage{pdfsync}, everything returned to normal. So these packages are incompatible, which is unfortunate.
