portare una tabella in una pagina da una risoluzione di 800*600 a 1024*768?

mi spiego meglio: ho bisogno di fare una pagina che ci stia senza problemi in una risoluzione da 800*600, ma che si possa espandere senza problemi in uno schermo a 1024*768.

codice:
<HTML>
	<HEAD>
		<TITLE>Introduzione alla ricerca</TITLE>
		<LINK HREF="Library/Style/shop.css" REL=STYLESHEET TYPE=TEXT/CSS>
	</HEAD>
		<BODY BGCOLOR=#FFFFFF LEFTMARGIN=0 TOPMARGIN=0 MARGINWIDTH=0 MARGINHEIGHT=0>
			<TABLE WIDTH=1000 BORDER=0 CELLPADDING=0 CELLSPACING=0 align="center">
				<tr>
					<td>
					
						<TABLE WIDTH=98% BORDER=0 CELLPADDING=0 CELLSPACING=0 align="center">
							<TR>
								<TD WIDTH=170 HEIGHT=70>[img]img/logo.gif[/img]</TD>
								<TD WIDTH=36%>[img]img/c.gif[/img]</TD>
								<TD WIDTH=468 HEIGHT=70 align="right">[img]img/banner5.gif[/img]</TD>
							</TR>
							<TR>
								<TD COLSPAN=3 background="img/sfbluline.gif" WIDTH=98% HEIGHT=9></TD>
							</tr>
						</table>
					
					</td>
				</tr>
				<tr>
					<td>
