Dear list,
I have another issue related to extreme tables.
\setupxtable[split=yes]
\starttext
\startmakeup[standard]
\dontleavehmode
\startxtable[align={middle,lohi},columndistance=0em]
\startxrow
\startxcell
\dontleavehmode
\externalfigure[cow.pdf]
[scale=500]
\stopxcell
\startxcell
\dontleavehmode
\externalfigure[cow.pdf]
[scale=500]
\stopxcell
\stopxrow
\stopxtable
\stopmakeup
\stoptext
When splitting extreme tables, I cannot use \dontleavehmode.
Since this worked before, am I missing something or is this a bug?
Many thanks for your help,
Pablo

1. What is the purpose of \dontleavehmode in your example?
2. Why do you try to split a table in a makup environment (which will
never work)?

It isn't a bug but a side effect of the way how split=yes works.
The normal splitters uses a simple placement method where each table row
is placed below each other. To prevent unwanted white space between the
lines \nointerlineskip is used but the command works only a vertical
mode. With \dontleavehmode like in your example you force horizontal
mode for the table which results in the error message.
You can reproduce the error with the following minimal example:
\starttext
\dontleavehmode
\vbox{}
\nointerlineskip
\vbox{}
\stoptext
The reason why this doens't happen when splitting is disabled or when
the header or footer lines are repeated is that ConTeXt puts the
collected lines for each table in a \vbox. When you flush the lines in
the \vbox the are placed in vertical modes and your \dontleavehmode is
only applied to the outer \vbox while the lines itself are placed in
vertical mode.
\starttext
\dontleavehmode
\vbox
{\vbox{}
\nointerlineskip
\vbox{}}
\stoptext

Sorry, Wolfgang, I forgot to mention.
\dontleavehmode is required to center the table when
\startmakeup[standard][align=center].

\setupxtable[split=yes] is a general setup for the whole document.
I mean, I don’t want a table in the document to be stuck between pages.
Only sometimes I have makeups with tables. And this was my first issue
with the conflicting general setup.
As written in my previous message, there was no clash some time (well,
five years 😅) ago.

Many thanks for your explanation.

You can use the float environment and disable the counter.
\starttext
\startplacefigure [location={none,split}]
\startxtable
\dorecurse{100}
{\startxrow
\startxcell xxx \stopxcell
\startxcell xxx \stopxcell
\stopxrow}
\stopxtable
\stopplacefigure
\stoptext
Another option is framedtext which can be centered.
\starttext
\startframedtext [location=middle,width=fit,frame=off]
\startxtable
\startxrow
\startxcell xxx \stopxcell
\startxcell xxx \stopxcell
\stopxrow
\stopxtable
\stopframedtext
\stoptext

When you short table keeping them together can be better or do you want
short tables with five rows to be split across pages.
