Thanks for catching this, I've just pushed up a fix for this issue. The
column headers were being lost during the export processing.

The exporter *does* take into account the :cache header, however, due to
the error above, the values of the inputs to the block of R code were
different on export than on interactive evaluation, so the cache was
invalidated as if the contents of the table had changed.
