Provides a set of fields that can be used to store tabular data with a node.

Code

function tablefield_field_is_empty($item, $field) {

  // @todo, is this the best way to mark the default value form?
  // if we don't, it won't save the number of rows/cols
  // Allow the system settings form to have an emtpy table
  $arg0 = arg(0);
  if ($arg0 == 'admin') {
    return FALSE;
  }

  // Check for already serialized data. This is the case for other language
  // versions of this field.
  if (!empty($item['tabledata'])) {
    return FALSE;
  }
  $count_rows = $item['tablefield']['rebuild']['count_rows'];

  // Remove the preference fields to see if the table cells are all empty.
  unset($item['tablefield']['caption']);

        // Keys denoting weight data and anything still iterateable should be
        // ignored while checking for empty cell data.
