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}
\starttext
\startbuffer[loop]
\startxrow
\startxcell[left] \cA \stopxcell
\startxcell[left] \cB \stopxcell
\startxcell[left] \cC \stopxcell
\startxcell[left] \cD \stopxcell
\startxcell \cE \stopxcell
\startxcell[left] \cF \stopxcell
\startxcell \cG \stopxcell
\startxcell \cH \stopxcell
\doifdefined{cI}{\startxcell \cI \stopxcell}
\doifdefined{cJ}{\startxcell \cJ \stopxcell}
\doifdefined{cK}{\startxcell [left] \cK \stopxcell}
\stopxrow
\stopbuffer
\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
