How about this:

[% IF reports %]
  [% FOREACH report IN reports %]
         <tr id="trcol[% (loop.count % 2) ? 1 : 2 %]">
             <td>[% report.DSTRCT_CODE %]</td>
             <td>[% report.WORK_ORDER %]</td>
             <td>[% report.CREATION_DATE %]</td>
             <td>[% report.LAST_MOD_DATE %]</td>
             <td>[% report.ORIGINATOR_ID %]</td>
             <td>[% report.SURNAME %]</td>
             <td>[% report.FIRST_NAME %]</td>
         </tr>
  [% END %]
[% ELSE %]
         <tr colspan="7">No reports</tr>
[% END %]

That removes the duplication in your original version, and handles the
case when no reports are available.  If you don't like the trinary
operator (? :) you could replace it with a simple IF ELSE statement. 
Also, if you don't mind renaming your styles, you can simplify it to
just use id="trcol[% loop.count % 2 %]", where your styles would then
be trcol0 and trcol1.
