Div anchor already Defined XHTML

[The Red]

In XHTML strict I have written a mock "table" using divs and css. This is in XHTML 1.0 Strict. When I validate it says that each of the contents (contntent1,2,3 ect) are alreay defined. Is there a work around for this that doesnt involve nameing
"100" different id names?

<div id="table">

	<div id="tableheader"><h2 class="table">Scotts Products</h2></div>
	

	
	<div id="col1">
	<div id="content1"><p class="1">Products</p></div>
		<div id="content1"><p class="1">Amount</p></div>
		<div id="content1"><p class="1">Price</p></div>
		<div id="content1"><p class="1">Shipping</p></div>		
		<div id="content2"><p class="1">Hot sauce</p></div>		
	</div>
	
	<div id="col2">
	<div id="content2"><p class="1">8 oz</p></div>
		<div id="content2"><p class="1">$8.00</p></div>
		<div id="content2"><p class="1">Standard Shipping</p></div>
		<div id="content2"><p class="1">Hot Nuts</p></div>
		<div id="content2"><p class="1">16 oz</p></div>	
	</div>
	
	<div id="col3">
	<div id="content3"><p class="1">$30.00</p></div>
		<div id="content3"><p class="1">Standard Shipping</p></div>
		<div id="content3"><p class="1">Wing Sauce</p></div>
		<div id="content3"><p class="1">8 oz</p></div>
		<div id="content3"><p class="1">$12.00</p></div>
	</div>
	
	<div id="col4">
	<div id="content4"><p class="1">Standard Shipping</p></div>
		<div id="content4"><p class="1">Scott Oil</p></div>
		<div id="content4"><p class="1">8 oz</p></div>
		<div id="content4"><p class="1">$9.00</p></div>
		<div id="content4"><p class="1">Standard Shipping</p></div>
	</div>
	
	
</div>

You're re-using <div id="content1"> 4 times and the others these should be classes.
