\recurselevel inside \bTABLE\eTABLE

\recurselevel inside \bTABLE\eTABLE

[Willi Egger]

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? 

knd regards

Willi

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

[Willi Egger]

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!

Needs \expanded:

\bTABLE
  \dorecurse{3}{\bTR\expanded{\bTD\recurselevel\eTD}\eTR}
\eTABLE

See my change, you have to put \expanded before \bTD because when you write

  \bTD \expanded{\recurselevel} \eTD

context will store “\expanded{\recurselevel}” which is expanded
after all cells are created and \recurselevel has its default value.
