Spliting data into colums

[freemancomputer]

I have been working on a way to split my data into 2 columns as a way to make the page shorter and easier to read. I have been able get it to split like this

 

1 2

3 4

5 6

 

But I would rather it go like this, because it would be easier on the eyes.

 

1 4

2 5

3 6

 

This is what I have now, I have no idea if I'm even on the right track.

  <?php
include"scripts/connect.php" ;

mysql_connect('localhost',$username,$password);
@mysql_select_db($database) or die( "Unable to select database");
$query="SELECT * FROM movies WHERE type LIKE 'tv' ORDER BY title";
$result=mysql_query($query);

$num=mysql_numrows($result);

mysql_close();
?>
<table width="70%" align="left">

<?php
$i=0;
while ($i < $num/2)
{

$title=mysql_result($result,$i,"title");

?>
<tr>
<td><a class="nav" href=/show.php?title=<?php echo urlencode($title); ?>><?php echo $title; ?></td>



<?php
while ($i >= $num/2)
{
?>

<td><a class="nav" href=/show.php?title=<?php echo urlencode($title); ?>><?php echo $title; ?></td>
</tr>


<?php
}
$i++;

}

?>
</table>

 

This will show only the first half of the titles.

 

Thanks in advance.
