For your report, printf is plenty sufficient (See sprintf for the formatting codes). For example:
use strict;
use warnings;
my $APPROX_LINES_PER_PAGE = 4;
my $sep = ('-'x60)."\n";
my $header = <<HEADER;
============================================================
Name Format of match matches played runs scored page %d
============================================================
HEADER
my $format = "%-18s %-8s %-15s %s\n";
my $cur_pers = '';
my $page = 0;
my $lines = 0;
while (<DATA>){
chomp;
my @elements = split /!/,$_;
if (0 == $page or $lines >= $APPROX_LINES_PER_PAGE) {
print $sep if $page;
print "\n";# or do whatever you want to do between pages
$page++;
$lines = 0;
$cur_pers = '';
printf $header, $page;
}
# check if person change
if ($cur_pers and $cur_pers ne $elements[0]) {
print $sep;
$lines++;
}
$cur_pers = $elements[0];
printf $format, @elements;
$lines++;
}
print $sep;
print "\n";

I've added some sample pagination - I'm not sure what you had in mind there, but you should be able to extend it to what you wanted.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
