What we see here is the distributive property of HTML shortcuts. if you don't want a tg be part of the dirtibution list, then just take it out:

 use CGI;

my $cgi = CGI->new();

print $cgi->Tr(
                {-align=>LEFT, -valign=>TOP}, 
                [
                    $cgi->td(
                        [
                            $cgi->a({-href=>"..", -target=>"_new"}, $c
+gi->img("blah.gif")),
                        ]
                    ) . 
                    $cgi->td(
                        {-OnClick=>"javascript:dothis()" }, 
                        [
                            $cgi->a({}, "a"),
                            $cgi->hidden(-name=>'name2', -value=>'b') 
+. $cgi->a("b"),
                            $cgi->hidden(-name=>'name3', -value=>'c') 
+. $cgi->a("c")
                        ]
                    )
                ]
            );

This gives:

<tr align="LEFT" valign="TOP">
<td><a target="_new" href=".."><img>blah.gif</img></a></td>
<td onclick="javascript:dothis()"><a>a</a></td> 
<td onclick="javascript:dothis()"><input type="hidden" name="name2" va
+lue="b" /><a>b</a></td>
<td onclick="javascript:dothis()"><input type="hidden" name="name3" va
+lue="c" /><a>c</a></td>
</tr>
