new page before xtable with repeated headers
Hello everyone, I'm having an xtable spanning several pages and need to have its headers repeated. For this I've set "split=repeat", but unfortunately this causes the table to start with a new new page leaving the rest of the preceding page empty. Having "split=yes" makes the tabe continue on the previous page as a need it to, but then the header isn't repeated any longer. I realize that there has been a very similar question already in https://www.mail-archive.com/ntg-context@ntg.nl/msg93775.html, but my problem happens isolated in a very clean situation w/o any header, floats or the like - and I don't see yet how I can get this working in my situation. Any help is highly appreciated, here is a MWE of my problem: \definextable[mytable] \setupxtable[mytable] [ option=max, split=repeat, %split=yes, header=repeat, width=\textwidth ] \definextable[mytable:header] \setupxtable[mytable:header] [ foregroundstyle=\bf, foregroundcolor=darkred, ] % ================================================== \startdocument \dorecurse{2} { \input tufte \vskip7mm } \startxtable[mytable] \startxtablehead \startxrow[mytable:header] \startxcell Some Header \stopxcell \startxcell More Header \stopxcell \stopxrow \stopxtablehead \startxtablebody \dorecurse{10} { \startxrow \startxcell {\bf (\recurselevel) some tale:} \startitemize \item a quick \item brown fox \item jumps over \item the lazy dog \stopitemize \stopxcell \startxcell {\bf and a fact:} \startitemize \item the vodka \item is good \item but the meat \item is rotten \stopitemize \stopxcell \stopxrow } \stopxtablebody \stopxtable \stopdocument Thank you very much i.a., Werner

You can put this on cont-new.mkxl as test: \unprotect \defcsname\??xtableflushsplit\v!repeat\endcsname {\doloop {\clf_x_table_flush method {\v!split}% height \ifdim\pagegoal=\maxdimen\textheight\else\dimexpr\pagegoal-\pagetotal\relax\fi \relax \ifcase\c_tabl_x_state \exitloop \else \page \fi}} \protect Please test a lot! I also needs Wolfgangs opinion on this. Maybe preceding whitespace can interfere so maybe we need some 'slack' parameter.

Thank you Hans, this works well in my unchanged MWE - I'll do some more rigorous testing on monday and let you know. Thanks a lot and hava a nice weekend! Werner Am 23.04.21 um 21:28 schrieb Hans Hagen:

I still rely in all my installations on this bit at the bottom to be in cont-new.mkxl. Is there a way to make this patch update-safe? There are comments in ./tex/texmf-context/tex/context/base/mkxl/cont-new.mkxl: %D This file is loaded at runtime, thereby providing an excellent place for hacks, %D patches, extensions and new features. There can be local overloads in cont-loc %D (which has always been the case) and experimental code in cont-exp (which is also %D so old that I need to remind myself to check it occasionally, so here is the %D reminder). I tried the mentioned local overload methods but didn't get them to work. Did I mess up somehow or is the comment above outdated? Are there any better ways - update-safe though?

\protect cont-new will be overwritten so when you put a patch in there you need to check a next upload if that patch is permanent
you can also put patched in a cont-loc file (make sure that you run mtxrun --generate after making one) and out that file in your texmf-local tree (or project tree) as these will not be replaced you can wrap such a patch in: \ifcsname\??xtableflushsplit\v!repeat\endcsname \else \fi to make sure that it's not overloading something built in Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
Hello Hans, loading from cont-loc now works, thank you! Am 31.05.21 um 11:33 schrieb Hans Hagen:

\ifcsname\??xtableflushsplit\v!repeat\endcsname \else
\fi
to make sure that it's not overloading something built in
if I do this, I get: suggestion > use \withcaron instead of \v and if I use \withcaron, then the wrapper seems to be OK, but the patch isn't loaded any more. Wasn't the patch meant to override an already existing\xtableflushsplit in this case? Thank you, Werner
