Tho Ralph may have answered your Q, I looked at your desired layout and feel it necessary to chime in.
A lot of people transitioning from tables layouts to CSS find this issue perplexing, and get stuck IN TRYING TO SOLVE how to do with DIVs what they did with TDs .
#1 That shouldnt be your goal.
#2 That shouldnt be your goal.

#1) Start by coding your HTML semantically.
#2) Now that you have coded your HTML semantically you can assign BGs to elements at needed, which 9/10 wont follow a “row” structure.
Looking at your intended output ( and assuming that TEACH CPR is a LOGO) naturally suggest this structure
<div id="hedWrap">
<h1>Teach CPR</h1>
<p>Call toll free</p>
<form...><p>..Alive tomorrow</p></from>
<ul id="mainnav"> <li><a href="#">Nave Item</a></li>...</ul>
</div>
Alternatively you could do away with the logo as content …
<div id="hedWrap">
<p>Call toll free</p>
<form...><p>..Alive tomorrow</p></from>
<ul id="mainnav"> <li><a href="#">Nave Item</a></li>...</ul>
</div>
Neither is a row structure ( you don’t need a col for the logo and col for other things!!!)
In fact, in the latter example you can achieve the same effect setting the same amount of padding-left, as the width of the logo, to the container as using the logo image as a bg.
BUT more realistically the name of your organization is content so let’s keep the H1, shall we?
<div id="hedWrap">
<h1>Teach CPR</h1>
<p>Call toll free</p>
<form...><p>..Alive tomorrow</p></from>
<ul id="mainnav"> <li><a href="#">Nave Item</a></li>...</ul>
</div>
#hedWrap{background:url (headgradient.gif) repeat-x #MactchingRed; }
h1{height: height of logo image px; width: width of logo image px; overflow:hidden; position:relative; float:left;}
h1:after{ position:absolute; top:0; left:0; height:100%; width:100%; background: url (logo.jpg) no-repeat; content:"";}
#hedWrap >p, #hedWrap form, #mainnav{ margin-left: width of logo image px}
That is a bare bones conceptual explanation, but you can see it is far simpler and also more semantically correct than merely trying to recreate tables with divs.
