=head1 NAME

Test2::EventFacet::Info::Table - Intermediary representation of a table.

=head1 DESCRIPTION

Intermediary representation of a table for use in specialized
L<Test::API::Context> methods which generate L<Test2::EventFacet::Info> facets.

=head1 SYNOPSIS

    use Test2::EventFacet::Info::Table;
    use Test2::API qw/context/;

    sub my_tool {
        my $ctx = context();

        ...

        $ctx->fail(
            $name,
            "failure diag message",
            Test2::EventFacet::Info::Table->new(
                # Required
                rows => [['a', 'b'], ['c', 'd'], ...],

                # Strongly Recommended
                as_string => "... string to print when table cannot be rendered ...",

                # Optional
                header => ['col1', 'col2'],
                collapse => $bool,
                no_collapse => ['col1', ...],
            ),
        );

        ...

        $ctx->release;
    }

    my_tool();

=head1 ATTRIBUTES

=over 4

=item $header_aref = $t->header()

=item $rows_aref = $t->rows()

=item $bool = $t->collapse()

=item $aref = $t->no_collapse()

The above are all directly tied to the table hashref structure described in
L<Test2::EventFacet::Info>.

=item $str = $t->as_string()

This returns the string form of the table if it was set, otherwise it returns
the string C<< "<TABLE NOT DISPLAYED>" >>.

=item $href = $t->as_hash()

This returns the data structure used for tables by L<Test2::EventFacet::Info>.

=item %args = $t->info_args()

This returns the arguments that should be used to construct the proper
L<Test2::EventFacet::Info> structure.

    return (table => $t->as_hash(), details => $t->as_string());
