Insert ad inside table view

Hello!
I am trying to insert ad inside table view, but when the result is rendered, I can see two ads, not just one, and the table become very wider.
I want to insert only one row with one column after the second view result. My code for the view-table.tpl.php is this

<?php
/**
 * @file views-view-table.tpl.php
 * Template to display a view as a table.
 *
 * - $title : The title of this group of rows.  May be empty.
 * - $header: An array of header labels keyed by field id.
 * - $header_classes: An array of header classes keyed by field id.
 * - $fields: An array of CSS IDs to use for each field id.
 * - $class: A class or classes to apply to the table, based on settings.
 * - $row_classes: An array of classes to apply to each row, indexed by row
 *   number. This matches the index in $rows.
 * - $rows: An array of row items. Each row is an array of content.
 *   $rows are keyed by row number, fields within rows are keyed by field ID.
 * - $field_classes: An array of classes to apply to each field, indexed by
 *   field id, then row number. This matches the index in $rows.
 * @ingroup views_templates

?>
<table class="<?php print $class; ?>"<?php print $attributes; ?>>
  <?php if (!empty($title)) : ?>
    <caption><?php print $title; ?></caption>
  <?php endif; ?>
  <thead>
    <tr>
      <?php foreach ($header as $field => $label): ?>
        <th class="<?php print $header_classes[$field]; ?>">
          <?php print $label; ?>
        </th>
      <?php endforeach; ?>
    </tr>
  </thead>
  <tbody>
    <?php foreach ($rows as $count => $row): ?>

      <tr class="<?php print implode(' ', $row_classes[$count]); ?>">
        <?php foreach ($row as $field => $content): ?>

          <td class="<?php print $field_classes[$field][$count]; ?>" <?php print drupal_attributes($field_attributes[$field][$count]); ?>>
<?php if ($count == 2) :?>   
<My AdSense code is here>

        <?php endif; ?>    
<?php print $content; ?>    
          </td>


        <?php endforeach; ?>
      </tr>


    <?php endforeach; ?>
  </tbody>
</table>

Please, give me any suggestion what I can add here to achieve this result? My table is with 2 columns, but the ad must be in single column after second result.
Thank you in advance!
