Hi Geert,

this approach is simpler:

    \starttext
    \startxtable
    \startxtablehead[head]
    \doloopif{\lineno}{<}{2}{\getbuffer[loop]}
    \stopxtablehead
    \startxtablebody
    \doloopif{\lineno}{>}{1}{\getbuffer[loop]}
    \stopxtablebody
    \stopxtable
    \stoptext

Only loop header with CSV lines numbered below 2, and loop boody with
CSV lines numbered above 1.
