You can play with this:

\def\linkeklammer
   {\setbox\scratchbox\hbox{$\left\{\vrule height .5\vsize depth 
.5\vsize width 0pt\relax\right.$}%
    \rightaligned{\hbox to 
.5\wd\scratchbox{\raise\dp\scratchbox\box\scratchbox\hss}}}

\def\rechteklammer
   {\setbox\scratchbox\hbox{$\left.\vrule height .5\vsize depth .5\vsize 
width 0pt\relax\right\}$}%
    \leftaligned{\hbox to 
.5\wd\scratchbox{\hss\raise\dp\scratchbox\box\scratchbox}}}

\defineoverlay[linkeklammer] [\linkeklammer]
\defineoverlay[rechteklammer][\rechteklammer]

\starttext

\bTABLE
   \bTR[align={middle,middle},frame=off,offset=1ex]
     \bTD[background=linkeklammer] text \eTD
     \bTD text\\text\\text \eTD
     \bTD[background=rechteklammer] text \eTD
   \eTR
\eTABLE

\stoptext

and this:

\startuseMPgraphic{accolade}
z1  = (-233,0) ;
z2  = (-220,22) ;
z3  = (-155,211) ;
z4  = (-200,690) ;
z5  = (-142,1033) ;
z6  = (-97,1106) ;
z7  = (-71,1125) ;
z8  = (-61,1104) ;
z9  = (-80,1077) ;
z10 = (-108,1002) ;
z11 = (-129,666) ;
z12 = (-117,207) ;

z25 = (-155,-211) ;
z26 = (-220,-22) ;
fill z1 for i=2 upto 14: .. z[i] endfor & z14 for j=15 upto 26: .. z[j] 
endfor .. z1 & cycle ;
