Ok, I understand that. In module dm_tests.pm at about line 2220, it checks 
all the OIDs on the row in the table for an 'ignore' or an 'only' 
directive. Thus you can select only certain rows to appear in the table. 
This is new for me.

Yes. In the same module, at about  line 2109, you can find:

        # Make the first oid (from left to right) the primary one
         my $pri = $1 if $line =~ /\{(.+?)\}/;

in which $line contains the row definition of the table. It assigns the 
first name enclosed between curly brackets to $pri. Further on this 
variable is used in the alarms selection:

           my $pri_val = $oids->{$pri}{'val'}{$leaf};
           my $alarm = 1; # Alarm by default
           my $a_val  = $dev->{'except'}{$test}{$pri}{'alarm'} ||
             $dev->{'except'}{'all'}{$pri}{'alarm'} ||
             $tmpl->{'oids'}{$pri}{'except'}{'alarm'};
           $alarm = ($pri_val =~ /^(?:$a_val)$/) ? 1 : 0  if defined $a_val;

           my $na_val = $dev->{'except'}{$test}{$pri}{'noalarm'} ||
             $dev->{'except'}{'all'}{$pri}{'noalarm'} ||
             $tmpl->{'oids'}{$pri}{'except'}{'noalarm'};
           $alarm = 0 if defined $na_val and $pri_val =~ /^(?:$na_val)$/;

So your proposal should work.
