Hello,
The sample below has 2 problems I cannot find the solution for:
I am reading a table from a CSV file and want to typeset it via \xtable.
The xtable as defined below works, it splits over several pages, but the header does not repeat. I have seen examples in the mailing list where people put the "\startxtable.....\stopxtable" within a \placefigure, but as soon as I try this, I get an error message: "missing } or endgroup", although I doublechecked the "}" and I see no error.
The other issue I have: Since xtable requires me to read the header line separately in order to put it between \startxtablehead and \stopxtablehead, I access the csv buffer twice: the first time, I only read the first line, and the second time, I read starting from the second line. My problem here is that I do not know beforehand the number of lines in the csv file. So in my second \doloopfromto I give the second argument a number high enough to be sure it reads all the lines. It works fine, but I would like to know if there is a way to read the number of lines in the csv file to use the exact number of lines, instead of guessing.
\usemodule[handlecsv]
\opencsvfile{systaprov2.csv}

\setupxtable[offset=0cm, frame=off, bottomframe=on, framecolor=gray, option=stretch, align=middle]
\setupxtable[head][background=color, backgroundcolor=gray, topframe=on, bottomframe=on, framecolor=black, foregroundcolor=blue]
\setupxtable[left][align=right]
\startxtable[header=repeat]
Add "split=repeat" to \startxtable.
\startxtablehead[head] \doloopfromto{1}{1}{\getbuffer[loop]} \stopxtablehead \startxtablebody \doloopfromto{2}{500}{\getbuffer[loop]} \stopxtablebody
\stopxtable
\stoptext
