If you want more control, retrieve the custom field values yourself, like this:
get_post_meta($post_id, $key, $single);
So you could do
<table>
<tr>
<td>Webinar name:</td>
<td>echo get_post_meta($post_id, 'webinar-name', true);<td>
</tr>
<tr>
<td>Launch date:</td>
<td>echo get_post_meta($post_id, 'launch-date', true);<td>
</tr>
etc.
