[NTG-context] Tables ..

Hi, I would like to use multipage tables. I had a look on the wiki and there are 2 ways of doing that. What is the advantage of using \startlinetable ? One of these seems to be that we can repeat columns .. Is Context going keep going with \startlinetable or not ? (As no doc exists and its developpement seems to be not finished yet) ? Thanks. Dirar.
