iban column missing from Webform results table

Problem

In the case where webform_iban is used in a Webform:

The IBAN column is missing from the Webform results table:

Solution

Fixed by implementing _webform_table_component()

/**
 * Implements _webform_table_component().
 */
function _webform_table_iban_field($component, $value) {
  return check_plain(empty($value[0]) ? '' : $value[0]);
}

this is how it looks after implementing _webform_table_component()
