//   <div id="tableout"></div>
//   <tag onclick="add_to_tabe('tableout', '<?php print htmlentities($out); ?>');">
// Parameters:
//   tableid     - ID of Div to insert into
//   text        - table to isnert into tableid
//   parent_elem - Optional, prepended to cur_display_id
// Other notes:
//   %X% in "text" is replaced with cur_display_id++
//   %Y% in "text" is shifted to "%X%"
