Re: printing out a table X wide and X down without html::template

This example uses Perl::CGI

#!/usr/bin/perl -w

use warnings;
use strict;

package main;
#
# I really like Perl::CGI  -- so this example incorporates it. 
#
use CGI;
use CGI::Carp qw(fatalsToBrowser);
my $q = new CGI;                        
my $human_legible = "\n";
print $q->header,                    
      $q->start_html('Table Example'),
      $q->h1('How to Format a table');         
#
# Add breaks so ppl can read the HTML output.
# This is an example after all.
#
print $human_legible;
#
# This is where we figure out spacing. It could be made into a
# function easily enough.
#
my $x_dim = 4;
my $y_dim = 5;
my $test_text = "This is a test";
my @array = ( $test_text, $test_text, $test_text, $test_text,
              $test_text, $test_text, $test_text );
my $table_rows = int((scalar @array) / $x_dim);
my $last_row_count = (scalar @array) % $x_dim;
#
# Print the table here.
#
print $q->start_table;
my $array_index = 0;
my $table_entries = "";
for ( my $r = 0; $r < $table_rows; $r++ ) {
    $table_entries = "";
    for ( my $j = 0; $j < $x_dim ; $j++ ) {
        $table_entries .= $q->td($array[$array_index]);
        $array_index++;
    }
    print $q->Tr($table_entries);
    print $human_legible;
}
$table_entries = "";
for ( my $i = 0; $i < $last_row_count ; $i++ ) {
    $table_entries .= $q->td($array[$array_index]);
    $array_index++;
} 
print $q->Tr($table_entries);
