=head1 NAME

ETL::Pipeline::Input::File::Table - Sequential input in rows and columns

=head1 SYNOPSIS

  ...

=head1 DESCRIPTION

CSV (comma separated values) or Excel spreadsheet files represent data in a
table structure. Each row is a record. Each column an individual field. This
role provides some attributes common for this type of data. That way you don't
have to reinvent the wheel every time.

=head1 METHODS & ATTRIBUTES

=head2 Arguments for L<ETL::Pipeline/input>

=head3 no_column_names

Tabular data usually has field names in the very first row. This makes it
easier for a human being to read. Sometimes, though, there are no field names.
The data starts on the very first row.

Set B<no_column_name> to B<true> for these cases. Otherwise, the input source
will load your first row of data as field names.

  $etl->input( 'Excel', no_column_names => 1 );
