The following "HTML" will do it. There actually is no height attribute for the table element, but commonly used browsers will pay attention to it, and if they ignore it, it's not a problem, the file will just be centered at the top.
<html><head><title>example</title></head>
<body
><table height="100%" width="100%">
<tr><td valign="middle" align="center">
<!-- normal object code in here - make sure to set a width and height -->
</td></tr>
</table>
</body></html>

Dreamweaver is not useful if you don't know what you are doing. You would benefit yourself by reading information on how to mark up HTML by hand. Otherwise, you'll always be helpless when browsers don't understand your code, and you'll end up guessing when you could be knowing. Dreamweaver is a tool, but it can't make well-made Web pages for you -- that's your responsibility.
If you're new to this, you may wish to read something like
Learning HTML 3.2 by Examples (
http://www.cs.tut.fi/~jkorpela/HTML3.2/ ), or, if you're
very new,
http://www.cs.tut.fi/~jkorpela/html-primer.html
The document about HTML 3.2 may seem out of date because the current version of HTML is 4.01 (and then there's XHTML 1.0 and 1.1, which are no more useful than HTML 4.01), but I still think it is an excellent place to learn the basics, and its author has much more useful information on his Web site as well. Later on, you will probably wish to learn things like CSS, and perhaps some of the aspects of HTML 4.01 that 3.2 lacks.
