[NTG-context] Bold rules with TABLE

Hi, As this is my first mail to the list I'd like to start by thanking Hans and all other ConTeXt contributors. I stumbled upon ConTeXt just recently and I have fallen in love badly. :) Now to my question. Is it possible to control the rule thickness of a specific frames with TABLE, i.e. something like \setupTABLE[row][1][bottomframe=1pt] \setupTABLE[column][1][leftframe=2pt] If not, I'd guess it could be possible to fake this by inserting extra rows and columns with zero height and width, respectively, and use the rulethickness parameter to change the thickness of all their frames. Since this approach would add extra complexity to the table definitions I hope that you have better solutions. Thanks in advance, Fredrik Sjunnesson
