=head1 NAME

Spreadsheet::HTML::Presets::Handson - Generate Handsontable HTML tables.

=head1 DESCRIPTION

This is a container for L preset methods.
These methods are not meant to be called from this package.
Instead, use the Spreadsheet::HTML interface:

  use Spreadsheet::HTML;
  my $generator = Spreadsheet::HTML->new( data => \@data );
  print $generator->handson;

  # or
  use Spreadsheet::HTML qw( handson );
  print handson( data => \@data );

=head1 METHODS

=over 4

=item * C

Styles table with Handsontable, a "data grid component with
and Excel-like appearance."

Generate an empty 100x20 data grid:

  handson( fill => '100x20' )

Uses Handsontable's JS API unless you specify another URI via
the C param. Also uses their CSS unless you
override with the C param.

  handson(
      handsonjs => '/dist/handsontable.full.js',
      css       => '/dist/handsontable.full.css',
  )

Uses Google's jQuery API unless you specify another URI via
the C param. Javascript will be minified
via L if it is installed.
