    The only reason you'd get that is if $table is not returned from $te->first_table_found.

    Try this to see whether HTML::TableExtract (which ISA HTML::Parser) has correctly parsed the HTML:

      $te->parse($content) || die "couldn't parse HTML\n";

      My code didn't died while parsing the content.

        OK let's take WWW::Mechanize out of the equation, for the moment. Does this stand-alone snippet work for you?

        use strict;
use warnings;

use HTML::TableExtract qw/ tree /;

my $html = <<EOT;
<html>
  <head>
    <title>test page</title>
  <head>
  <body>
    <table>    
      <tr><td>parse me</td></tr>
    </table>    
  </body>
</html>
EOT

my $te = HTML::TableExtract->new;
$te->parse($html);

my $table = $te->first_table_found;
my $tree = $table->tree;

print $tree->cell(0,0)->as_text;

        BTW, your test HTML is malformed (there's no closing <head> tag), but that doesn't affect the output of the script, at least on my machine...

    Well it works for me (whereas with your code I get the same error as you).
