Thank you, Vit! I'm glad that the example on the wiki was wrong about 
that (there was a "not possible" mark) :)



And here another question. I think it has already been asked a couple of 
times, but perhaps not in this context: I would like the first row (or 
column or the whole table) to have a thicker border, like in this example:

*===*===*===*
H   |   |   H
*===*===*===*
H   |   |   H
*---*---*---*
H   |   |   H
*===*===*===*

(H,=: thick; |,-: thin)

There is a dirty solution for it: prepare 16 different border types with 
Metafun (every possible combination of thin and thick border lines) and 
set the proper one for every single cell touching at least one thick border.


A dash could be used to define an additional frame spanning over more 
than one row or column:

\setupTABLE
    [1-3] % not equal to [1,2,3]; 1-3 handled as a single frame
    [1,2-3] % in this case almost equivalent to [1,1-3]
    [rulethickness=2pt]

or as in this example:

*---*---*---*
|   |   |   |
*===*===*===*
|   |   |   |
*---*---*---*
|   |   |   |
*---*---*---*

\setupTABLE
    [1-3]
    [1] % or [1-1]
    [frame=off,bottomframe=on,rulethickness=2pt]

(Special care should be taken where nx= or ny= is used and crosses the 
border.)

Does there already exist any similar functionality?

What about commands like:
     [left|right|top|bottom]offset=
     [left|right|top|bottom]framecolor=
     [left|right|top|bottom]rulethickness=
in \setupframed?

(the last two options may lead to uneven effects in the corners when 
misused)

Thank you,
