[NTG-context] Table

Hi, for a bilingual book (german-arabic) I want to use a table. So far I have this one: \starttabulate[||p(.46\textwidth)|p(.46\textwidth)||] But that is not exactly, what I want: I want a table with 3 columns. The left one ist left-aligned, for the german text (left-algined in the usual sence, I understood that these terms are opposite in context?), the middle one is empty (just to control the space between the to text-columns), and the right columns, arabic, is right aligned. I want to control all three by something like ".46\textwidth", and no indentation (like the above result, left column is indented). How to achieve this (simple) table? My tries did not work so far.
