game compas spacing

[Q695]

compass size=132X132

 

How do I make this compass work properly:

<?php
function d_button($dx, $dy){
?>
<form method="post">
<input type="hidden" name="dir_x" value="<?php echo $dx;?>">
<input type="hidden" name="dir_y" value="<?php echo $dy;?>">
<input type="image" height="44px" width="44px" onclick="submit();" src="images/invisible.gif">
</form>
<?php
}

function direction(){
?>
<table border="0" cellpadding="0" cellspacing="0" width="132px" height="132px" background="images/compas.gif">
   <tr>
      <td><?php d_button(-1, 1);?></td>
      <td><?php d_button(0, 1);?></td>
      <td><?php d_button(1, 1);?></td>
   </tr>
   <tr>
      <td><?php d_button(-1, 0);?></td>
      <td width="44px"><td>
      <td><?php d_button(1, 0);?></td>
   </tr>
   <tr>
      <td><?php d_button(-1, -1);?></td>
      <td><?php d_button(0, -1);?></td>
      <td><?php d_button(1, -1);?></td>
   </tr>
</table>

<?php
}
?>
