FWIW, I think is awkward usage and produces badly dated HTML.

print $cgi->start_Tr({-id => "thisID", -valign => "top"});

This is equivalent, less verbose, and less awkward–

print '<tr id="thisID" valign="top">';

I often use CGI to produce HTML but the strength lies in being able to tersely, e.g.–

print table( Tr( td( \@long_list_of_td ) ) );

So, for your use, I’d much rather inherit something like this–

print Tr({-id => "thisID", -class => "CSSclass"},
         td("some stuff"),
         td("etc")
         );
