Hi,

Hm, I am puzzled.

When running the attached minimal file with
This is pdfeTeX, Version 3.141592-1.11a-2.1 (Web2c 7.5.2)
ConTeXt  ver: 2004.6.21  fmt: 2004.6.22  int: english  mes: english

There is a pdf with the expected one-cell table.

Otherwise running the file with
This is pdfeTeX, Version 3.141592-1.20a-2.2 (Web2c 7.5.3)
ConTeXt  ver: 2005.01.05  fmt: 2005.1.5  int: english  mes: english

or running the file with
This is pdfeTeX, Version 3.141592-1.20a-2.2 (Web2c 7.5.3)
ConTeXt  ver: 2005.01.13  fmt: 2005.1.15  int: english  mes: english
