Buggy ConTeXt table macros?

[James Ramsey <jjramsey_6x9eq42@yahoo.com>]

I'm not sure if \DL, \DC, and \DR are buggy or just
not quite documented yet. The following table seems to
work, though it looks to me like it shouldn't:

\starttable[|l|w40|l|w4|]
\NC Signed \NC \NC Date \NC \NC \NR
\DC \DL \DL \DR
\NC \NC (President) \NC \NC \NC\LR
\stoptable

This table gets me

Signed _____________________  Date _____
           (President)

which is what I want; however, the table looks like
its missing a \DC between the two \DL's.

This table, which I found in an unanswered post in the
ConTeXt mail archive doesn't work, and I can't find a
way to make it work:

\starttable[|l|l|l|l|l|]
\NC 1 \NC 2 \NC 3 \NC 4 \NC 5 \NC\AR
\DL[2] \DL[2] \DR
\NC 1 \NC 2 \NC 3 \NC 4 \NC 5 \NC\AR
\stoptable

This table is supposed to look like the following:

1 2 3 4 5
---   ---
1 2 3 4 5

What is going on?
