Split mysql output into two columns

Alright, so I had some guy create this php script for me that is basically a workout logger. When you go to print your workouts however, they are just in one column running down the page. So, if you have multiple workouts, it is going to take two sheets of paper to print them all out. What I want to do is split the workouts evenly into two columns no matter how many workouts are present. Here is my code so far:

<?php 
include("include/connection.php");
$css=mysql_query("select * from style");
$re_css=mysql_fetch_array($css);
print_r(($re_css['css']));
$color=unserialize(($re_css['csscolors']));
//print_r ($color);
$bgcolor=$color['page_bgcolor'];
//print_r($_SESSION);
//echo"<br><br>";
//print_r($_COOKIE);
//if (isset($_COOKIE[]==)

?>



<table cellpadding="6" cellspacing="1" border="0" width="60%" align="center" bgcolor="#FFFFFF">

<tr>
	<td align="center">

		<div align="left">
			


					    <table width="100%" cellpadding="0" cellspacing="0" border="0" align="">
						<?php 
						//echo'cxzccz  '. $_REQUEST[work_id];
						 $sl=mysql_query("select * from lift where workt_id = '".$_REQUEST[work_id]."'");
						while($sl1=mysql_fetch_array($sl)){
						?>
				          <tr>
				         <td align="center" nowrap >
                         <U><h4><?php 	echo $sl1['liftname'];?></h4></U> 
						 </td>												    
						</tr>
						<TR>
							<TD height="10"></TD>
						</TR>
							<?php if ($sl1['lift_id']!=''){
							  $s2=mysql_query("select * from  sets where lift_id='".$sl1['lift_id']." '");
							 if(mysql_num_rows($s2)>0){
							?>
						 <tr>
						  <td align="" nowrap >
					       <TABLE width="100%" cellpadding="0" cellspacing="0" border="0">
						    <TR>
						
							<TD width="25%" align="center" valign="top">
								  <B>Weight</B>								  </TD>
							<TD width="25%" align="center" valign="top">
								  <B>New Weight</B>								  </TD>
					
							<TD width="25%" align="center" valign="top"><B>Reps</B></TD>
							<TD width="25%" align="center" valign="top"><B>New Reps</B></TD>
							
						   </TR>
						    <TR>
							<TD colspan="4" height="10"></TD>
						   </TR>
					      </TABLE>
					 </td>												    
					</tr>
						 <?php
						   while($sl2=mysql_fetch_array($s2)){
						 ?>
					   <tr>
						 <td align="" nowrap >
							<TABLE width="100%" cellpadding="0" cellspacing="0" border="0">
								<TR>
								
									<TD width="25%" align="center" valign="top"><?php echo $sl2['sets'];?></TD>
									<TD width="25%" align="center" valign="top">__________</TD>
									<TD width="25%" align="center" valign="top"><?php echo $sl2['rep'];?></TD>
									<TD width="25%" align="center" valign="top">__________</TD>
									
								</TR>
								<TR>
									<TD colspan="6" height="10">&nbsp;</TD>
								</TR>
							</TABLE>
						 </td>												    
						</tr>
						
				<?php 
					}
				  }
				 }

				
			}?>
				<TR>
							<TD align="center"><INPUT TYPE="button" value="Print" onclick="print()">&nbsp;&nbsp;<INPUT TYPE="button" value="Close" onclick="window.close()"></TD>
						</TR>
				</table>
             
		
		
		</div>
	</div>
	<!--
	<div style="margin-top:6px">
		<input type="submit" class="button" value="Go Back" accesskey="s" onclick="history.back(1); return false" />
	</div>
	-->
	</td>
</tr>
</table>

</div>	
	</div>
</div>

The first image below is what it looks like currently, and the second image below is what I want it to look like.



Thanks for all your help!
