how about Using table tag attributes.

use Data::Dumper;
use HTML::TableExtract;
use Text::Table;


my $content = './table.html';
my $headers = ['subhead1', 'subhead2'];

#my $te = HTML::TableExtract->new(headers => $headers);
my $tbl_extr = HTML::TableExtract->new(attribs => { border => 1 });
my $tbl_out = Text::Table->new(@$headers);


$tbl_extr->parse_file($content);



foreach my $ts ($tbl_extr->tables) {
        print "Table with border=1 found at ", join(',', $ts->coords),
+ ":\n";
        foreach my $row ($ts->rows) {
                print "   ", join(',', @$row), "\n";
        }
}
