# ABSTRACT: Manipulate table-like data structure via table object

=head1 NAME
Data::TableData::Object - Manipulate table-like data structure via table object
=head1 VERSION
This document describes version 0.116 of Data::TableData::Object (from Perl distribution Data-TableData-Object), released on 2022-05-19.
=head1 DESCRIPTION
This module provides a common interface to manipulate a few kinds of data
structures that are "table-like": aoaos (array of array-of-scalars), aohos
(array of hash-of-scalars), aos (array of scalars, viewed as a single-column
table), and hash (viewed as two-column table with the columns being "key" and
"value').
The interface (see L<Data::TableData::Object::Base>) allows you to list columns,
add/delete columns, retrieve rows, convert to aoaos or aohos, etc.
=for Pod::Coverage ^$
=head1 FUNCTIONS
=head2 table
Usage:
 my $obj = table($data[ , $spec ]); # => obj
Shortcut for C<< Data::TableData::Object->new(...) >>.
=head1 METHODS
=head2 new
Usage:
 my $obj = Data::TableData::Object->new($data[ , $spec ]); # => obj
Detect the structure of C<$data> and create the appropriate
C<Data::TableData::Object::FORM> object. Note: if C<$data> is already a table
data object ("isa Data::TableData::Object::Base"), then C<$data> will be
returned as-is instead of creating a new object.

=head1 CONTRIBUTING
To contribute, you can send patches by email/via RT, or send pull requests on
GitHub.
Most of the time, you don't need to build the distribution yourself. You can
simply modify the code, then test via:
 % prove -l
If you want to build the distribution (e.g. to try to install it locally on your
system), you can install L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>, and sometimes one or two other
Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required
beyond that are considered a bug and can be reported to me.

patch to an existing test-file that illustrates the bug or desired
