I refined the proposal a little further to not having to overload xtables but only use one remaining internal macro of xtables. I also sent this version to Hans to be considered going to the ConTeXt core. \unprotect %D xtable extensions \definextable[XTABLE] \unexpanded\def\startXTABLE {\bgroup \let\NC\tabl_xte_start_nc \let\NR\tabl_xte_start_nr \settrue\c_tabl_xte_first_nc \tabl_x_start_named{XTABLE}} \newconditional\c_tabl_xte_first_nc \unexpanded\def\tabl_xte_start_nr {\stopxcell\stopxrow \settrue\c_tabl_xte_first_nc} \unexpanded\def\tabl_xte_start_nc {\ifconditional\c_tabl_xte_first_nc \setfalse\c_tabl_xte_first_nc \expandafter\startxrow\expandafter\startxcell \else \expandafter\stopxcell\expandafter\startxcell \fi} %D The related structure commands are also available: \let\startXTABLEhead\startxtablehead \let\startXTABLEfoot\startxtablefoot \let\startXTABLEnext\startxtablenext \let\startXTABLEbody\startxtablebody \let\stopXTABLEhead\stopxtablehead \let\stopXTABLEfoot\stopxtablefoot \let\stopXTABLEnext\stopxtablenext \let\stopXTABLEbody\stopxtablebody \protect \starttext \startXTABLE[align={lohi,middle}] \startXTABLEhead \NC OSI-Schicht \NC[nx=6] Umsetzung \NR \stopXTABLEhead \startXTABLEbody \NC Anwendungsschicht \NC[nx=2,ny=3] SOME/I \NC[nx=2,ny=3] AVB/TSN \NC[nx=2,ny=3] DoIP \NR \NC Darstellungsschicht \NR \NC Sitzungsschicht \NR \NC Transportschicht \NC[nx=3] TCP \NC[nx=3] UDP \NR \NC Vermittlungsschicht \NC[nx=3] IPv4 \NC[nx=3] IPv6 \NR \NC Sicherungsschicht \NC[nx=6] Ethernet \NR \stopXTABLEbody \startXTABLEfoot \NC Bitübertragungsschicht \NC[nx=2] 100BASE-TX \NC[nx=2] 100BASE-T \NC[nx=2] 1000BASE-T \NR \stopXTABLEfoot \stopXTABLE \stoptext On 03/08/2017 04:49 PM, Henri Menke wrote:
Alternatively to my first proposal but still overloading the original xtables I came up with another solution which does not have the \NC\NR but only \NR and does not read the cell content as an argument.

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!

Dear devs,
Natural Tables are quite handy but their syntax is a little verbose.
\bTABLE \bTR \bTD ... \eTD \eTR \eTABLE
There exist nice extensions which make the format less verbose by mapping
\startTABLE \NC ... \NR\NR \stopTABLE
back to the original macros.
The new method for tables, called xtables, is faster and seems to have less problems than Natural Tables. However, the syntax is even more verbose
\startxtable \startxrow \startxcell ... \stopxcell \stopxrow \stopxtable
Can we have similar abbreviations as for Natural Tables? I am thinking of something like
\startXTABLE \NC ... \NR\NR \stopXTABLE
I tried myself rewriting tabl-nte.mkiv for xtables but it is not straightforward.
What do you think of this proposal?
Kind regards, Henri
