[TYPO3-seminars] list view: subtitle or teaser below title

[Dirk Fischer]

Hi,

how can I have subtitle or teaser
as second line below the title
in the same <td> of the list view?

I tried in seminars_pi1.tmpl:
<!-- ###LISTITEM_WRAPPER_TITLE### --> 
<td###CLASS_LISTTITLE###>###TITLE_LINK### ###SUBTITLE###</td>
<!-- ###LISTITEM_WRAPPER_TITLE### -->
and it works, but there is also a column with subtitle, which is redundant.

Title           | Subtitle        | Date       |
Seminar ABC     | Additional Info | 23.05.2011 |
Additional Info |                 |            |

To delete this in seminars_pi1.tmpl:
<!-- ###LISTITEM_WRAPPER_SUBTITLE### --> 
<td###CLASS_LISTSUBTITLE###>###SUBTITLE###</td>
<!-- ###LISTITEM_WRAPPER_SUBTITLE### -->
still shows the table header "Subtitle", but with the content of the 
next column (date).

Title           | Subtitle        | Date       |
Seminar ABC     | 23.05.2011      |            |
Additional Info |                 |            |

hideColumns doesn't help. In this case the subtitle disappears complete.

Is there a way to get the subtitle or teaser below the title in the same 
<td>?

Regards
Dirk
