You could create a link as a row number as your first column.

while (@row = ...) {

        # include the rownum as part of the link
        print Tr( td( [a({-href=>"XXX".++$rownum}, "$rownum"), @row] )
+ );

        # Or, just the rownum with a different link
        #print Tr( td( [a({-href=>"XXX"}, ++$rownum), @row] ) );
}
[download]

Update: you could replace XXX with the URL of your cgi script and add a rownum param via GET. I.e. ... [a({-href=>"http://localhost/script_to_read_rownum.cgi?rownum=".++$rownum}, $rownum), ...]
