[NTG-context] xtable headers and handlecsv loop

[Geert Dobbels]

Pablo,

Gracias, your suggestion with \rownums works.  I will try this one too,
since it is a simpler solution.  By the way, All information I have
about handlecsv comes from the PDF file you wrote.  \rownums and \lineno
are not explained in this document.  Do you know of documentation that
describes those aspects ?
