Thanks for the suggestion, but as illustrated by the second example, copied here, where the section title is at the top of the page:
\starttext \showframe \dorecurse{50}{a } \startsection[title=spec][before={\blank[preference,big]}, after={\blank[samepage,big]}]
Your settings in the second argument of \startsection make no sense because the optional argument is for userdata (values like author etc.)
\startxtable \startxrow \startxcell[ny=30]a\stopxcell\startxcell 1\stopxcell \stopxrow \dorecurse{29}{\startxrow\startxcell 2\stopxcell\stopxrow} \stopxtable \stoptext
it is sometimes difficult to predict how much remaining space should trigger a line break.
You can either reformat your table or put the table in a float environment to move it to a place where it fits. Wolfgang
