Hi all!

I try to use ConTeXt to set tables specified with the CALS table model. 
Everything that is needed for this task is provided by the natural 
tables. Yet, the results are rather unsatisfactory. In particular I 
encounter the following problems:

1. The table header that is to be repeated after every page break 
includes a lot of whitespace. This white space is not contained in the 
provided input.

2. The frames of cells are extended bellow the bottom margin if there is 
  a nr-attribute greater than one and a page break is necessary.

In order to illustrate these problems, I attach a ConTeXt file and the 
produced pdf.

Does anyone know about these problems? Is there a workaround?

Thanks for your attention,

--Stefan
