Wolfgang,

Thanks for this.  It works, however, the page where the table starts has
three lines of text before the table starts.  After inserting
"split=repeat", the table jumps to the next page, leaving the rest of
the page with the three lines of text completely blank.  This did not
happen without the "split=repeat".
