Hi Brian,

I will show a few solution to your problem for the following table.
We will start with a simple table that contains the error.

\starttext

\bTABLE
  \bTR
    \bTD
      {\bTABLE
      \bTR
        \bTD SSSS \eTD
        \bTD Swap \eTD
      \bTR
    \eTABLE}
    \bTD
  \eTR
\eTABLE

\stoptext


Your own solution with adding a strut to the inner table can be done
in a better way by adding the strut to the setup of the beginning of the
table.

\starttext

\bTABLE
  \bTR
    \bTD
      {\bTABLE[left=\strut]
        \bTR
          \bTD SSSS \eTD
          \bTD Swap \eTD
        \bTR
      \eTABLE}
    \bTD
  \eTR
\eTABLE

\stoptext



Another mothod is to use the same method, that is used for the
outer table. I took a look into the source and found the following method,
that works also.

\starttext

\bTABLE
  \bTR
    \bTD
      {\bTABLE[strut=yes,autostrut=no]
         \bTR
           \bTD SSSS \eTD
           \bTD Swap \eTD
         \bTR
       \eTABLE}
    \bTD
  \eTR
\eTABLE

\stoptext


After that a was interested why we need to set the values in the
last example again, because they are already set in core-ntb.
The solution is, the values in nested tables are removed and replaced
by new ones. This behaviour can be changed and is shown in my last
example.

\starttext

\setfalse\resetTABLEmode

\bTABLE
  \bTR
    \bTD
      {\bTABLE
         \bTR
           \bTD SSSS \eTD
           \bTD Swap \eTD
         \bTR
       \eTABLE}
    \bTD
  \eTR
\eTABLE

\stoptext


Another example that shows the effect of \resetTABLEmode is:

\starttext

%\settrue\resetTABLEmode % default setting

\setupTABLE[frame=off]

\bTABLE
  \bTR
    \bTD
      {\bTABLE\bTR\bTD Text \eTD\eTR\eTABLE}
    \eTD
    \bTD
      Text
    \eTD
  \eTR
\eTABLE

\setfalse\resetTABLEmode

\bTABLE
  \bTR
    \bTD
      {\bTABLE\bTR\bTD Text \eTD\eTR\eTABLE}
    \eTD
    \bTD
      Text
    \eTD
  \eTR
\eTABLE

\stoptext
