I'm just switching from LaTeX, too, so don't expect too much from me. But I
think that
\starttable[|l|c|c|c|]
\NC \NC \NC\TWO{Agent 2} \NC\SR
\NC \NC \NC C \NC D \NC\SR
\DC \DC \DL[2] \DR
\NC \LOW{Agent 1} \NC C \VL $(-5,-5)$ \VL $(-1,-10)$ \VL\SR
\DC \DC \DL[2] \DR
\NC \NC D \VL $(-10,-1)$ \VL $(-2,-2)$ \VL\SR
\DC \DC \DL[2] \DR
\stoptable
solves your problem. A possibility for the alignment at the comma may be
\starttable[|l|c|r s0|l s3 |r s0 |l s3|]
\NC \NC \NC\FOUR\JustCenter{Agent
2} \NC\SR
\NC \NC \NC\TWO\JustCenter{C} \NC
\TWO\JustCenter{D} \NC\SR
\DC \DC \DL[4] \DR
\NC \LOW{Agent 1} \NC C \VL $(-5$ \NC $,-5)$ \VL $(-1$ \NC
$,-10)$ \VL\SR
\DC \DC \DL[4] \DR
\NC \NC D \VL $(-10$ \NC $,-1)$ \VL $(-2$ \NC
$,-2)$ \VL\SR
\DC \DC \DL[4] \DR
\stoptable
This is something like r@{,}l in LaTeX... At least it works. I put the
comma in the second column to get correct spacing. Maybe Hans or another
more experienced contexter knows a better solution to the alignment
problem. With natural tables, there is an alignment character, but I don't
know if this is the case with table and tabulate, too. And I'm not sure if
it could actually work in this case, since you don't simply want to type a
number with a decimal comma, but a pair of numbers in math mode, separated
by a comma.
The vertical alignment of 'Agent 1' is not perfect, though. Time for a
question: Is there a possibility to span an arbitrary number of rows and
align some text vertically centered in the resulting space? (ny=3 like in
natural tables, with additional centering?) The multirow package does this
for latex (quite well, except for very special cases).
Btw, there are some examples of tables in the beginners' manual which are
not (yet?) in the english beta reference manual, so you may want to have a
look at this.
I think tables are a topic where the context documentation (at least the
english one) ought to be extended, especially for newcomers and 'converts'
from latex. As soon as I am more experienced, and as soon as I have
finished my current work (diploma thesis), I would be willing make
contributions in this area (although the first precondition might take some
time...)
