Tabulate: vertical distance between rows

Tabulate: vertical distance between rows

Hello,

are there more ways how to affect vertical distance between rows within \start/stop-tabulate?

1) There is one, described on wiki (http://wiki.contextgarden.net/Tabulate):

----
\unprotect
\appendtoks
   \blank[halfline]
\to \t_tabl_tabulate_every_after_row
\protect

...
----

Its problem is that I don't know how to call it by Lua.
The following code fails:

----
   \startluacode
     context[[
\unprotect
\appendtoks
   \blank[halfline]
\to \t_tabl_tabulate_every_after_row
\protect
]]
   \stopluacode

...
----

So how to make it acceptable by Ctx?


2) Is there another way, e.g. inserting something each time before \NC\NR or elsewhere)?

This brings no effect:

----
   \starttabulate[|l|r|]
     \NC a \NC b \blank\NC\blank\NR
     \NC A \NC B \NC\NR
   \stoptabulate
----

As I intend to typeset a table (into tabulate) via Lua, adding an extra sequence/command anywhere when a table row is typeset is no problem.

Questions are: a) what would be such sequence and b) where it should be placed?


My whole testing code is attached.

Thank you in advance.

Best regards,

Lukas

This is only a hack and shouldn’t be used.

You can use the \TB which accepts the same keywords as \blank.

\starttext

\starttabulate
\NC one  \NC two   \NC\NR 
\NC two  \NC three \NC\NR 
\TB[line]
\NC four \NC five  \NC\NR 
\TB[1cm]
\NC six  \NC seven \NC\NR 
\stoptabulate

\stoptext
