Jim, you might try this (untested) patch, and provide your own function for
rowRenderCallback. I'd be interested to know how this works.
Note that this currently is only implemented for when USE_ARRAY_JOIN==false.
It can't be done in the same way for when USE_ARRAY_JOIN==true, so this is not
an appropriate patch for long-term. There should be some common way of doing
it so that both work, though.
