Use natural or extreme tables.

\starttext

\startxtable[frame=off,topframe=on,bottomframe=on]
     \startxrow
         \startxcell[width=.45\textwidth]
             Cause
         \stopxcell
         \startxcell[width=.1\textwidth]
             % empty cell
         \stopxcell
         \startxcell[width=.45\textwidth]
             Effect
         \stopxcell
     \stopxrow
     \startxrow[align={flushleft,lohi}]
         \startxcell
             text a
         \stopxcell
         \startxcell
             text b
         \stopxcell
         \startxcell
             \input knuth
         \stopxcell
     \stopxrow
\stopxtable

\stoptext
