'Tabular View' formatter disappears when Vote Up/Down (vote_up_down) module is enabled.

This has been fixed in 7.x-2.4 version on tablefield. There is no specific mention in the release notes (from what I can see), however I can confirm these two changes now exist in the module:

/**
 * Implements hook_field_info().
 */
function tablefield_field_info() {
  return array(
    'tablefield' => array(
      'label' => t('Table Field'),
      'description' => t('Stores a table of text fields'),
      'default_widget' => 'tablefield',
      'default_formatter' => 'tablefield_default',
      'property_type' => 'tablefield',
      'property_callbacks' => array('tablefield_property_info_callback'),
    ),
  );
}

/**
 * Implementation of hook_field_formatter_info().
 */
function tablefield_field_formatter_info() {
  return array(
    'tablefield_default' => array(
      'label' => t('Tabular View'),
      'field types' => array('tablefield'),
    ),
  );
}

I'll close this issue, as the patch in #1 amounts to the same.

thanks @reallifedesign.

fyi, this was fixed in https://www.drupal.org/node/2167059 which was mentioned in release notes.

Good catch @vitalie. I couldn't immediately spot that issue as the one that resolves this tablefield_default formatter issue. So it looks like this issue is practically and officially fixed.
