=head1 NAME
Text::Table::TSV - Generate TSV
=head1 VERSION
This document describes version 0.002 of Text::Table::TSV (from Perl distribution Text-Table-TSV), released on 2019-01-17.
=head1 SYNOPSIS
 use Text::Table::TSV;
 my $rows = [
     # header row
     ['Name', 'Rank', 'Serial'],
     # rows
     ['alice', 'pvt', '123456'],
     ['bob',   'cpl', '98765321'],
     ['carol', 'brig gen', '8745'],
 ];
 print Text::Table::TSV::table(rows => $rows);
=head1 DESCRIPTION
This module provides a single function, C<table>, which formats a
two-dimensional array of data as TSV. This is basically a way to generate TSV
using the same interface as that of L<Text::Table::Tiny> (v0.03) or
L<Text::Table::Org>.
The example shown in the SYNOPSIS generates the following table (Tab might be
shown as spaces):
 Name    Rank    Serial
 alice   pvt     123456
 bob     cpl     98765321
 carol   brig gen        8745
=for Pod::Coverage ^(max)$
=head1 FUNCTIONS
=head2 table(%params) => str
=head2 OPTIONS
The C<table> function understands these arguments, which are passed as a hash.
=over
=item * rows (aoaos)
Takes an array reference which should contain one or more rows of data, where
each row is an array reference.
