How can I select from only one table with Web::Scraper?

Question

I want to extract the text only for heading Node Object Methods from a webpage. The specific HMTL part is as follows:

Node Object Properties

Web::Scraper can use nth_of_type to choose the right table. There are two tables with the same class, so you can say table.reference:nth-of-type(2):

use v5.22;

use feature qw(postderef);
no warnings qw(experimental::postderef);


use Web::Scraper;

my $html = do { local $/;  };

my $methods = scraper {
    process "table.reference:nth-of-type(2) > tr > td > a", 'renners[]' => 'TEXT';
    };
my $res = $methods->scrape( $html );

say join "\n", $res->{renners}->@*;

And here's a Mojo::DOM:

use Mojo::DOM;

my $html = do { local $/;  };

my $dom = Mojo::DOM->new( $html );

say $dom
    ->find( 'table.reference:nth-of-type(2) > tr > td > a' )
    ->map( 'text' )
    ->join( "\n" );

I tried looking for a selector solution that could recognize the text in the h2, but my kung fu is weak here.
