I've tried reading pdf::table documentation.

But there's not any mention to vertical alignment

My example code is:

#!/usr/bin/perl
use strict;
use PDF::API2;
use PDF::Table;

my $pdftable = new PDF::Table;
my $pdf = new PDF::API2(-file => "pdf_table.pdf");
my $page = $pdf->page();
$pdf->mediabox('A4');
 
my $col_props = [
    {
        justify => 'right', 
        font => $pdf->corefont("Helvetica", -encoding => "utf8"),     
+   
        font_size => 12,
        min_w => 100,       
        max_w => 100,       
    },    
    {
        justify => 'left', 
        min_w => 100,       
        max_w => 100,       
    }
];

my $data = [ 
    ['title0', "content 0" ],
    ['title1', "first line\nsecond line\nthird line"],
    ['title2', "content 2"],
    ['title3', "content 3"],
    ['title4', "content 4"],
    ['title5', "content 5"],
    ['title6', "content 6"]
] ;

# build the table layout
my ($end_page, $pages_spanned, $table_bot_y) =  $pdftable->table(
    $pdf,
    $page,
    $data,
    x => 40,
    w => 200,
    start_y => 500,
    next_y  => 700,
    start_h => 300,
    next_h  => 500,
    padding => 5,
    padding_right => 10,
    column_props   => $col_props,    
);    

$pdf->saveas();

The cell of second row and second column takes three lines. Than I want to align vertically centered the content of all other columns of that row. I could'nt find any indication in the documentaion. Thank's</>
