[NTG-context] help with xtreme tables

Hi, I have a table with around 120 rows and 120 columns which fits an A0 paper. I want it to be split so that it fits A4 sized papers. When I tried using xtables : \startxtable[split=repeat,header=repeat] \startxtablehead ... \stopxtablehead \startxtablebody .... . . . .... \stopxtablebody the table rows get split into different pages, but the columns get cut at the right edge of the page. Is there a way to split the columns as well (repeating the first column as necessary)? Also, what is the use of grouping rows within \startxtablenext and \stopxtablenext? Note: I am just typing the outline of the code as the cell definitions is very long and hopefully my requirement is clear without the entire cell definitions. Thanks, ajith
