in thread How to fetch table element from a site into data

Yes, it works! :) Can you tell me how can I put these things in a hash with key as the header and the contents as the value. So that the o/p should be like this: 
$hash = {
     company => ('Island Trading', 'Galerφa del gastr≤nomo'
+, 'Laughing Bacchus Wine Cellars', 'Paris spΘcialitΘs', 'Si
+mons bistro', 'Wolski Zajazd')
     country => ('UK','Spain','Canada','France','Denmark','Poland')
}

    One way is to populate arrays for both company and country with the elements from the dereferenced array reference ($row->[0]: company name; $row->[1]: country name), and then use those arrays to create strings (values) that will be associated with company and country keys. The script, as a whole, would then look like this:

    use Modern::Perl;
use WWW::Mechanize;
use HTML::TableExtract;

my ( %hash, @company, @country );

my $mech = WWW::Mechanize->new();
$mech->get('http://www.w3schools.com/sql/default.asp');
my $html_string = $mech->content();

my $te = HTML::TableExtract->new( headers => [ ( 'Company', 'Country' 
+) ] );
$te->parse($html_string);

for my $ts ( $te->tables ) {
    for my $row ( $ts->rows ) {
        push @company, qq|'$row->[0]'|;
        push @country, qq|'$row->[1]'|;
    }
}

$hash{'Company'} = '(' . ( join ', ', @company ) . ')';
$hash{'Country'} = '(' . ( join ', ', @country ) . ')';

say "$_ => $hash{$_}" for sort keys %hash

    Output:

    Company => ('Island Trading', 'Galería del gastrónomo', 'Laughing Bacc
+hus Wine Cellars', 'Paris spécialités', 'Simons bistro', 'Wolski Zaja
+zd')
Country => ('UK', 'Spain', 'Canada', 'France', 'Denmark', 'Poland')
