Would be nice and quite useful to have a class for the column.

So instead of:

<th><a href="#" class="sortheader">Cron Trigger<span class="sortarrow">&nbsp;&nbsp;↑</span></a></th>
...
<td>Poll SCM: H 8-16 * * 1-5<br>H 18 * * 7</td>

Something like:

<th class="column-cron"><a href="#" class="sortheader">Cron Trigger<span class="sortarrow">&nbsp;&nbsp;↑</span></a></th>
...
<td class="column-cron">Poll SCM: H 8-16 * * 1-5<br>H 18 * * 7</td>

This way it would be much easier and quicker to create customizations. For example I have script that makes long cron info shorter by default (screen). Part of the script is searching for the correct header number which is not a nice and stable way to do that.
