Dear all,

I got the error "You can't use '\prevdepth' in restricted horizontal mode” when I compile the following code.

If I remove “\starttabulete… \stoptabulate”, then no errors, but the out put is not the form of table.

How can I fix this error?

Thank you.

Best regards,

Dalyoung

\starttext

\startluacode
  function makeHead(a)
    local n = #a 
    
    context.HL()
    for i = 1, n  do
      context.NC() context(a[i])
    end
    context.NC()context.AR()
    context.HL()
  end
\stopluacode

%\starttabulate[|mcw(1cm)|mcw(1cm)|mcw(1cm)|mcw(1cm)|]
  \startluacode
    local a = {"x","y","z","(x\\to y)"}
    makeHead(a)
  \stopluacode
%\stoptabulate
