Guys, Im having some trouble with some tables. Im not very good at making a layout I guess. I've been viewing the source of alot of websites and trying to study the code though.

Anyways can anyone paste this code into frontpage or dreamweaver and look at it? I cant get the BLACK columns to line up with the rest of the top. The width is a little to wide I think, but I cant figure it out.

PHP Code:
<table border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111" width="100%" id="AutoNumber1" height="700">
  <tr>
    <td width="100%" height="700">&nbsp;<p>&nbsp;</p>
  
      <center>
      <table border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111" width="98%" id="AutoNumber2" height="553">
        <tr>
          <td width="16%" height="553">&nbsp;</td>
          <td width="68%" height="553">
          <table border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111" width="692" id="AutoNumber3" height="25" bgcolor="#C0C0C0">
            <tr>
              <td width="11" rowspan="2" height="25">
              <img border="0" src="file:///C:/Documents%20and%20Settings/JonB/Desktop/topleft.gif" width="11" height="25"></td>
              <td bgcolor="black" width="669" height="2"></td>
              <td width="12" height="25" rowspan="2">
              <img border="0" src="file:///C:/Documents%20and%20Settings/JonB/Desktop/topright.gif" width="11" height="25"></td>
            </tr>
            <tr>
              <td width="669" height="19">&nbsp;</td>
            </tr>
          </table>
          <table border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111" width="691" id="AutoNumber4" height="450" bgcolor="#C0C0C0">
            <tr>
              <td bgcolor="black" width="2" valign="top" align="left" height="450">&nbsp;</td>
              <td width="85" height="450">&nbsp;</td>
              <td width="523" height="450">&nbsp;</td>
              <td width="75" height="450">&nbsp;</td>
              <td width="4" height="450" bgcolor="#111111" align="right" valign="top">&nbsp;</td>
            </tr>
          </table>
          </td>
          <td width="16%" height="553">&nbsp;</td>
        </tr>
      </table>
      </center> 

Mostly Im just having troubles making tables that have graphics on the outside of them (the curvy ones) so that you can make a table with rounded edges, kinda like at www.cheathouse.com
