colspan counter wrong

May you attach a screenshot of the settings page?

I have already fixed that problem in the development snapshot; if this is still a problem in the development snapshot, then feel free to re-open this report.

It seems that depends from the theme used.

Also changing the theme from Bluemarine to Garland, the table is shown correctly.
I am not sure how the code should be fixed; to verify which theme is being used, and then changing a parameter passed to the table theme function doesn't seem the correct way to proceed.

I tried increasing the value of the attribute colspan, and it seems to work.
I guess that I must count all the columns present in the table, including the ones that will be hidden.

Thanks for the report, and the help in confirming the issue.

I think that colspan is needed to put both the operations under the column Operations; differently, only the first link would appear under that column.

See the code used by a Drupal core function (2 operation links, and attribute colspan set to 2):

function contact_admin_categories() {
  $result = db_query('SELECT cid, category, recipients, selected FROM {contact} ORDER BY weight, category');
  $rows = array();
  while ($category = db_fetch_object($result)) {
    $rows[] = array($category->category, $category->recipients, ($category->selected ? t('Yes') : t('No')), l(t('edit'), 'admin/build/contact/edit/'. $category->cid), l(t('delete'), 'admin/build/contact/delete/'. $category->cid));
  }
  $header = array(t('Category'), t('Recipients'), t('Selected'), array('data' => t('Operations'), 'colspan' => 2));

  return theme('table', $header, $rows);
}

Would make sense to report what Nodewords does, when you are suggesting that Nodewords is doing something not correct? Indeed, it would not make sense. That is the reason I reported what Drupal code does.
