Weave.jl generating tables for the pdf doctype

I am having an hard time generating tables with Weave.jl using the pdf doctype. For the html doctype i can generate decent tables using PrettyTables.jl. While most options of PrettyTables do not work in Weave, i can at least tune the column width and a few other things, but that does not seem to work for the pdf doctype. Without setting the column width the tables are printed all skrewed up.

Can someone share experience on how to generate tables with Weave for the pdf doctype?
