Hi All,

I'm trying to get a table header with such bottom border:
|============|

I plan to use an overlay to overlap the the internal borders of the cells. But in this case, the table header somehow slightly shifted to the left relative to the body (see attachment). Is it possible to remove this effect? Or maybe there is another way to achieve the desired border? Thanks.

\startuseMPgraphic{MP:thickBtm}
   draw (0,2pt)--(OverlayWidth,2pt) withpen pensquare scaled 1pt withcolor red;
   clip currentpicture to OverlayBox;
   setbounds currentpicture to OverlayBox;
\stopuseMPgraphic

\defineoverlay[OL:thickBtm][\useMPgraphic{MP:thickBtm}]

\starttext
 \bTABLE
   \setupTABLE[align=middle]
   \setupTABLE[header][background={foreground,OL:thickBtm}]
   %
   \bTABLEhead\bTR\dorecurse{3}{\bTH#1\eTH}\eTR\eTABLEhead
   \bTABLEbody\dorecurse{6}{\bTR\dorecurse{3}{\bTD#1-##1\eTD}\eTR}\eTABLEbody
 \eTABLE
\stoptext
