How to iterate over an sObject in Visualforce

Hi All,

Please see my code below

<table class="section">
        <tr>
            <apex:repeat value="{!hostedHeaders}" var="header">
                <th><apex:outputText value="{!header}"></apex:outputText> </th>
            </apex:repeat>   
        </tr>       
        <apex:repeat value="{!hostedProducts}" var="hProd">
        	<tr>
	       		<apex:repeat value="{!hProd}" var="prod">
	       			<td><apex:outputText value="{!prod}"></apex:outputText> </td>
	           	</apex:repeat>  
            </tr>
        </apex:repeat>
    </table>

I'm trying to dynamically create a table for an email template.  The table will have a dynamic number of columns.  The above visualforce markup is controlled by a custom controller on the back end and I can provide it if needed but I don't want to overly complicate things.

HostedProducts is a list of OpportunityLineItem.  The controller decides which OLI fields are queried and sent back to the component.  I want to display every queried field for each OLI returned.  Because this is dynamic, I don't know the field names until runtime.  So I can't use the typical {!hprod.unitprice}.

Any direction would be appreciated.

Thanks,

Max

    use this syntax

    {!header[fieldVar1]}

    {!prod[fieldVar2]}

    where fieldVar = dynamic field variable

    As a common practice, if your question is answered, please choose 1 best answer. 

    But you can give every answer a thumb up if that answer is helpful to you. 

    Thanks
