Well, I don't know how IPB works or exactly how you want it to work, but it would be something like this, if sent.
CODE
<?php
echo("
<table>
<tr>
<td style=\"background-color: green;height:
30px;\"><center>Trigger</center></td>
</tr>
<tr>
<td style=\"background-color: gray;height: 20px;\">Players</td>
</tr>
<tr>
<td>" . $_POST['players'] . " </td>
</tr>
<tr>
<td style=\"background-color: gray;height: 20px;\">Conditions</td>
</tr>
<tr>
<td>" . $_POST['conditions'] . " </td>
</tr>
<tr>
<td style=\"background-color: gray;height: 20px;\">Actions</td>
</tr>
<tr>
<td>" . $_POST['actions'] . " </td>
</tr>
</table>
");
?>
This should work, assuming that the information is passed through $_POST, which it probably isn't. You replace the $_POST['players'] and all with whatever IPB uses. You still need to format everything else; as said before, if I had information about how IPB works, it would be much easier. You need to insert it in the PHP document where it processes BBcode.
