Don't add `(1-1/2)` after the table name. Just only put the table name.

Otherwise, if you think it would be a good idea to have it as a comment, you can use the [comment syntax](http://symfony.com/legacy/doc/reference/1_4/en/02-YAML#chapter_02_comments):

```yaml
table: export_certificate_request_info_forms # (1-1/2)
```

(Make sure to put a space before the `#` sign).
