Okay first of all I started by making a prototype with this code. 
#!/usr/bin/perl -w
use strict;
my @array        = qw(0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 1
+9 20);
my $rows          = 2;
my $row_count  = 0;
my $array_total = 7;
 
print "[START]\n"; 
for(my $i = 1; $array_total >= $i; ++$i) {
    if ($row_count == 0) {
        $row_count += 2;
        print "$array[$i] ";
    } elsif ($i == $array_total) {
        print "$array[$i]";
    } elsif ($rows == $row_count) {
        $row_count = 0;
        print "$array[$i]\n";
    } else {
        ++$row_count;
        print "$array[$i] ";
    }
}   
print "\n[END]\n";

Which works fine when you change $rows or $array_total, then when I went to implement that into my code I came up with something like this 
#!/usr/bin/perl -w
use strict;
my $total_sites = 7;
my $row_count = 0;
my $rows = 2;  
print "<table border=\"1\" width=\"100%\" cellpadding=\"3\" cellspacin
+g=\"3\">\n\n";
for(my $i = 1; $total_sites >= $i; ++$i) {
    if ($row_count == 0) {
        $row_count += 2;
        print "  <tr valign=\"top\">\n    <td width=\"100%\">\n";
        print "        number: [$i]\n";
        print "    </td>\n\n";
    } elsif ($i == $total_sites) {
        print "    <td width=\"100%\">\n";
        print "        number: [$i]\n";
        print "    </td>\n\n";
    } elsif ($rows == $row_count) {
        $row_count = 0;
        print "    <td width=\"100%\">\n";
        print "        number: [$i]\n";
        print "    </td>\n\n  </tr>\n\n";
    } else {
        print "    <td width=\"100%\">\n";
        print "        number: [$i]\n";
        print "    </td>\n\n";
    }
}
print "  </tr>\n\n</table>\n";

The problem is if $rows is anything other than 2 it doesn't work, I can't figure out why it's not doing the block 
    } elsif ($rows == $row_count) {
        $row_count = 0;
        print "    <td width=\"100%\">\n";
        print "        number: [$i]\n";
        print "    </td>\n\n  </tr>\n\n";

to print out the close table row tag like it does with the first script for the newlines.
