[NTG-context] Setting a maximum table/column width

Hi, The "excursion" manual describes how to use w(dim) to set a column's minimum width. Is there a way to set a column's maximum width so that text automatically wraps around? Alternatively, is there a way to set a table's maximum width so that it doesn't get wider than \textwidth? I tried using \SetTableToWidth{} at random locations but I either got errors or no improvement whatsoever. Thanks, Flavio
