Hi Brian,

the best method to control nested tables is by integrating a setup
command for nested tables.

\def\setupresetTABLE
  {\dodoubleargument\getparameters[\@@tbl\@@tbl\@@tbl]}

\def\resetallTABLEparameters% moet genest wel werken
  {\ifnum\TBLlevel>\plusone % in ieder geval
     \ifconditional\resetTABLEmode
       \presetlocalframed   % breedte hoogte diepte offset
         [\@@tbl\@@tbl]%    % achtergrond, achtergrondraster,
achtergrondkleur \copyparameters
         [\@@tbl\@@tbl][\@@tbl\@@tbl\@@tbl]

          \c!style,\c!option,\c!maxwidth,\c!textwidth,\c!left,\c!right]
     \else
       \setupTABLE
         [\c!width=\v!fit,
