I created a table using tabulate. I want the header to repeat, and used the following code. The table splits correctly, but the header doesn't repeat. Any idea why the header doesn't repeat?

\setuptabulate[split=yes,header=repeat]

\starttabulatehead

\HL

\NC  \bf  Variable     \NC     \bf Value  \NC    \bf Reference        \NR

\HL \HL

\stoptabulatehead

\starttabulate[|lw(1in)|lw(1in)|l|]

\dorecurse{100}{\NC  Column 1 value \NC  Column 2 value \NC  Ref. Column 3 value  \NC \AR} \stoptabulate
