Table select does not respect rowspans

This also applies to HEAD.

Patch still applies cleanly to both 6 and 5.

Please avoid making pointless follow-ups under the pretext of cleaning up the issue queue.

<?php
  function test_form() {
    $form['checks'] = array('#type' => 'checkboxes', '#options' => array(0 => '', 1 => ''));
    return $form;
  }

  function theme_test_form($form) {
    $header = array(theme('table_select_header_cell'), 'col1', 'col2');
    $checks = array(drupal_render($form['checks'][0]), drupal_render($form['checks'][1]));

    $rows1 = array(
      array($checks[0], 'row11', 'row12'),
      array($checks[1], 'row21', 'row22')
    );

    $rows2 = array(
      array(array('data' => $checks[0], 'rowspan' => 2), 'row101', 'row102'),
      array('row111', 'row112'),
      array(array('data' => $checks[1], 'rowspan' => 2), 'row201', 'row202'),
      array('row211', 'row212')
    );

    return theme('table', $header, $rows1) . theme('table', $header, $rows2);
  }

  return drupal_get_form(test_form);
?>

If the above code is stuck into a new node and previewed using the PHP filter, it should display two tables that use checkboxes. Clicking a checkbox in the second table should demonstrate that the highlighting is broken when the checkbox is set to span more than one row.

I've only tested this against D5. At the time of rolling, this patch also applied to D6 - no idea about now, though.

Thanks,
