Why is there so much space begin modules?

Can someone review the following code and tell me why so much space is being displayed between each module in the left sidebar? If you can suggest a better way to code it would be apprecitated. Code is displayed at link below.

<div class="sb-search"><h2><?php _e('Search','k2_domain'); ?></h2>
<?php include (TEMPLATEPATH . '/searchform.php'); ?>
</div>
<!-- END SEARCH -->
<table >
<tr><td height ="200">
<h2>Categories & Tags</h2>
<?php UTW_ShowWeightedTagSetAlphabetical("coloredsizedtagcloud","",0) ?>
</td></tr></table>
<li> <h2>Most Popular Posts</h2>
<ol class="tex2">
<?php akpc_most_popular(); ?>

</li>
akpc_most_popular($limit = 10, $before = <li>, $after = </li>)
<div class="sb-comments sb-comments-blc">
