Dear Dalyoung,

Ah, indeed you're right. Sorry about that!
After experimenting with the code a bit, it seems that centering does not work if either the second or last column has a specified width. (I do not know whether this is a bug or due to something I don't understand in how tables work.)

I can see two possibilities:

* If that works for you, you can replace the line
\starttabulate[|cw(0.7cm)|cw(0.7cm)|cw(1cm)|cw(1cm)|]
with
\starttabulate[|cw(0.7cm)|c|cw(1cm)|c|]
(The MetaPost drawing may need to be adjusted.)

* If not, you may manually center the title using e.g. the \offset command as shown below. (I presume there is a way to compute the correct offset from the column widths and write a macro to avoid having to fine-tune it by hand.)

Dear Florent Michel,

Thank you for the checking.
As you said, using \starttabulate … \stoptabulate makes “[2][c]” disappear.
But q is not at the center of the row.
There may be something more to do that I don’t know.

Thank you again.

Best regards,

Dalyoung

Hi,

Not sure whether that's the best solution or not, but your example seems to work on my side if I replace \starttable with \starttabulate and \stoptable with \stoptabulate as follows:

_________________________________________________________________

\startuseMPgraphic{recBox}{w,h,sx,sy,lColor}
numeric u; u := 1cm;
draw unitsquare xyscaled (\MPvar{w}, \MPvar{h}) shifted (\MPvar{sx},\MPvar{sy}) withpen pencircle scaled 3pt withcolor \MPvar{lColor};
\stopuseMPgraphic
\defineoverlay
[kBox]
[\useMPgraphic{recBox}{w=2u,h=LineHeight+4pt, sx=.8u,sy=LineHeight-2pt,lColor=darkred}]

\starttext

\framed[frame=on,background=kBox]{
\starttabulate[|cw(.7cm)|cw(.7cm)|cw(1cm)|cw(1cm)|]
\HL
\NC \NS[2][c] q \NC\AR
\NC p\NC \NC 00 \NC 01\NC\AR
\HL
\NC 1 \NC 2 \NC 3 \NC 4\NC\AR
\NC 1 \NC 2 \NC 3 \NC 4\NC\AR
\NC 1 \NC 2 \NC 3 \NC 4\NC\AR
\NC 1 \NC 2 \NC 3 \NC 4\NC\AR
\NC 1 \NC 2 \NC 3 \NC 4\NC\AR
\HL
\stoptabulate
}
\stoptext

Sorry.
Here is a sample code.

Thank you.

Best regards,

Dalyoung
