HTML Right Navigation

Can you please provide a link to your test page.  

I am confused.  You have code for the left side, but not the right? I may be missing something but I'm  not sure how to help with that.

In simple terms you can create a wrapper class with the width, then give the left class a width and float it left and do the same for the right class.  Just make sure the 2 widths equal the width of the wrapper in px or %

<div class="wrapper">
    <div class="col-left">left</div>
    <div class="col-right">right</div>
</div>

So out of this original code where would I insert and end the div command?

<center> 
  <table border="0" cellspacing="0" cellpadding="0" width="800" bgcolor="#000000" valign="TOP"> 
    <tbody> 
      <tr> 
        <td bgcolor="#ffffff" valign="top" width="800" align="center"><img width="800" src="/spaw/getimg.php?img=home_files/header.jpg" /></td> 
      </tr> 
    </tbody>

              <tr>

Are you using tables and tables inside of tables for a layout?    If so, stop and start over.  You are in for a mess and a broken site.

Start with a css grid and I prefer responsive.  http://getbootstrap.com/  or http://foundation.zurb.com/

In any case, you don't have enough code to help you.  I am actually even more confused. Your question states your code is for a left nav but your new code shows that in the 5th column.

Please create a very simple test page and post the link here or perhaps recreate it in jsbin.com or jsfiddle for us to look at.

Ya I did not add the right side code in yet.  I'm just modifying the page.  I didn't create it.  I was showing you the leftnav that is already in place.  I need to add a rightnav or page to it.
