Hello, thanks for explanation.
I also wrote a sample code which should typeset a midaligned table via Lua using
"tabulate".
But I'm not able to achieve the goal - what am I doing wrong?
----
\starttext
T
\startluacode
local f = function()
context.starttabulate{"|rw(2cm)|rw(2cm)|"}
context.NC()
context("A")
context.NC()
context("B")
context.NC()
context.NR()
context.stoptabulate()
end
f()
context("U\\par")
context.startalignment{"middle"}
context("V") -- OK, "V" is successfully midaligned
context.stopalignment()
context.startalignment{"middle"}
f() -- Wrong, table is not midaligned
context.stopalignment()
context.startalignment{"middle"}
context.dontleavehmode()
f() -- Wrong, too, table is still not midaligned (?!)
context.stopalignment()
-- context.midaligned(f) -- This breaks Ctx!
\stopluacode
\stoptext
----
Best regards,
Lukas

What are differences (or intended usage) among \centerline, \midaligned, \startalignment[middle]? (NB: \centerline has no its-own page on wiki, but it is used at several places in wiki samples. \centerline was also mentioned here in the mailing list, when I was trying to center "tabulate" - and neither \midaligned nor \startalignment[middle] combined with \dontleavehmode worked.)The three commands - \leftline, - \rightline and - \centerline are copied from plain TeX and allow you to center short text which fits on a single line but it isn’t recommended to use them because ConTeXt has it’s own alternative for them. The replacement commands are - \leftaligned, - \rightaligned and - \midaligned. Even though each command is only meant for short text you use the \\ command to put text into several lines, e.g. \starttext \midaligned{One\\Two\\Three} \stoptext creates three lines for the input. In recent installations you can write \startlinealignment[left|middle|right] … \stopalignment as a alternative to \leftaligned etc. With the alignment environment you can change the alignment of the text for a certain region. Unlike the line alignment environment you can use text which covers more than a single line. \starttext \input knuth\par \startalignment[middle] \input knuth\par \stopalignment \stoptext Wolfgang
