Can't get print alignment correct

PHP
1

this code works correctly except that the print table doesn’t align correctly and the totcharges doesn’t display the decimals. Can someone look at this and advise?

<?php
mysql_connect(localhost,root,"");
mysql_select_db(oodb) or die( "Unable to select database");
$query=" SELECT * FROM oocust WHERE payrec = 'R' AND pd = ' '";
$result=mysql_query($query);
$num=mysql_numrows($result);
echo date("m/d/Y") . "<br />";
echo "<font size=+2><b> Old Orchard Plumbing Invoices Due Report</font></b></b><br />";
echo "<table cellspacing=1 cellpadding=0 border=0>

</tr>";
while($row = mysql_fetch_array($result))
{
// $charges=$row['charges'];
// $tax=$row['tax'];
// $amtdue=$row['amtdue'];
$totcharges = $totcharges + $row['charges'];
$tottax = $tottax + $row['tax'];
$totamtdue = $totamtdue + $row['amtdue'];
