Widget: Field labels aren't hidden.

Field titles are shown in both the table header and as labels on each row, here is a potential fix:

 function multifield_table_pre_render_field($element) {
-  $multifield_info = field_info_field($element['#field_name']);
-  foreach (multifield_type_get_subfields($multifield_info['type']) as $field_name) {
+  foreach (multifield_type_get_subfields($element['#field_name']) as $field_name) {
     ...
   }
 }
