Re: [NTG-context] \recurselevel inside \bTABLE\eTABLE

17 Mar 2013

      Thank you again!

Sorry for misspelling your name Aditya!

I was surprised, that the solution of Wolfgang does not work, with \expanded{\recurselevel}, though it sounds reasonable. Still all rows are marked 0. Alan's suggestion gives me the desired result.

Hm, I was not yet thinking about using cld... Thank you Hans!

Dear all,
I should prepare a form with a table. The table rows should be numbered.
How can I get get this done by using \recurselevel.
In the attached minimal example all rows are numbered with 0.
\starttext
\subject{bTABLE--eTABLE: recurse creates rows}
\bTABLE
   \dorecurse{3}
       {\bTR
           \bTD \recurselevel \eTD
       \eTR}
\eTABLE
What do i do wrongly here?
You’re doing nothing wrong but you have to expand the value of the
counter.
One feature of natural tables is the calculated width of the cells, to
do this context stores
the content of all cells in a token register, i.e. context stores
\recurselevel as content
of the cell and not the value of the iteration. This content is
processed after all cells
have been stored and the \recurselevel macro uses at this moment its
default value 0.
To expand the value of the counter use \expanded{…} to force a expansion.
\bTABLE
\dorecurse{3}{\bTR\bTD\recurselevel\eTD\eTR}
\eTABLE
There was a long discussion on this a couple of years back. Summarized
here:

or
\startluacode
 context.bTABLE()
   context.bTR()
     context.bTD()
     context.mathematics("(+)")
     context.eTD()
     for y = 1,6 do
       context.bTD()
         context(y)
       context.eTD()
     end
   context.eTR()
   for x = 1,6 do
     context.bTR()
       context.bTD()
         context(x)
       context.eTD()
       for y = 1,6 do
         context.bTD()
           context(x+y)
         context.eTD()
       end
     context.eTR()
   end
 context.eTABLE()
\stopluacode
