I cannot centred the map too. Workaround is to dup the satellite map next to it, just like kksou shown in the document. UNLESS kksou can tell us! I am from Australia!
You can create the map border - try the code below;
<p>Westfield Penrith</p>
<h4>Two cities two columns:</h4>
<table border="1">
<tbody>
<tr>
<td>
</td>
<td>
</td>
</tr>
<tr>
<td>Westfield Penrith</td>
<td>97 Victoria Ave, Chatswood, NSW, Australia</td>
</tr>
</tbody>
</table>
<p>Eastern suburb branches</p>
<table border="2">
<tbody>
<tr>
<td>
</td>
</tr>
<tr>
<td>Randwick</td>
</tr>
</tbody>
</table>
