Vertical text alignment in nested natural tables

["Brian R. Landy" <landy@alumni.caltech.edu>]

Hi,

I am having a problem using nested natural tables, to which I have a  
solution but feel that it my not be the proper approach.  I'm pretty  
much a TeX and ConTeXt novice.

The problem is that the row height it reduced when a table is nested,  
breaking vertical text alignment across cells.  In my example the  
cells "SSSSS" and "Swap" to not align vertically due to the presence  
of the "p".  I have an example of the problem and my fix below.

I'm curious if someone knows a better way to fix this.

Thanks for your help,
Brian



\starttext
Working table:\par
\start
\bTABLE[frame=on,align={middle,lohi}]
\bTR
\bTD SSSSS \eTD
\bTD Swap \eTD
\eTR
\eTABLE
\stop

Nested table changes cell height, breaks text alignment with "lohi":\par
\start
\bTABLE[frame=on,height=0.50in]
\bTR
\bTD
{\start
\bTABLE[frame=on,align={middle,lohi}]
\bTR
\bTD SSSSS \eTD
\bTD Swap \eTD
\eTR
\eTABLE
\stop}
\eTD
\eTR
\eTABLE
\stop

setting height to baselineskip does not help:\par
\start
\bTABLE[frame=on,height=0.50in]
\bTR
\bTD
{\start
\bTABLE[height=\the\baselineskip,frame=on,align={middle,lohi}]
\bTR
\bTD SSSSS \eTD
\bTD Swap \eTD
\eTR
\eTABLE
\stop}
\eTD
\eTR
\eTABLE
\stop

One fix is a strut:\par
\start
\bTABLE[frame=on,height=0.50in]
\bTR
\bTD
{\start
\bTABLE[frame=on,align={middle,lohi}]
\bTR
\bTD \strut{SSSSS} \eTD
\bTD \strut{Swap} \eTD
\eTR
\eTABLE
\stop}
\eTD
\eTR
\eTABLE
\stop
\stoptext
