I quickly came up with something myself. Unfortunately, it involves
overloading of the original xtables. Perhaps there is a better way but it
works. I am happy to hear your opinions!
\unprotect
% Overload tabl_x_start_table
\unexpanded\def\tabl_x_start_table[#settings]% maybe two arguments:
[tag][settings] | [tag] | [settings]
{\bgroup
\let\NC\tabl_xte_start_nc
\let\NR\tabl_xte_start_nr
\tabl_x_prepare{#settings}%
\edef\tabl_x_current_buffer{\tabl_x_default_buffer}%
\buff_pickup{\tabl_x_current_buffer}{startxtable}{stopxtable}\relax\tabl_x_process\zerocount}
% xtable extensions
\newconditional\c_tabl_xte_in_nc
\unexpanded\def\tabl_xte_start_nr
{\stopxrow
\setfalse\c_tabl_xte_in_nc}
\unexpanded\def\tabl_xte_start_nc
{\futurelet\next\tabl_xte_start_nc_indeed}
\def\tabl_xte_start_nc_indeed
{\ifx\next\tabl_xte_start_nr \else
\expandafter\tabl_xte_start_nc_finish
\fi}
\def\tabl_xte_start_nc_finish#1\NC
{\ifconditional\c_tabl_xte_in_nc \else
\settrue\c_tabl_xte_in_nc
\startxrow[]%
\fi
\startxcell#1\stopxcell\NC}
\protect
\starttext
