I am trying to embed a DataTable inside of a DataTable.  Please help me understand what I'm doing wrong.

Note: I have never gotten this to work, so my approach may be completely off.

<apex:datatable id="tblQuotes" value="{!quotes}" var="q">
    <apex:column >
	<apex:outputText value="{!q.name}" />
    </apex:column>
    <apex:column>
	<apex:param name="provQuoteId" value="{!q.id}" />
	<apex:dataTable id="tblQlis" value="{!quoteLineItems}" var="qli">
	    <apex:column value="{!qli.id}" />
	</apex:dataTable>
    </apex:column>
</apex:datatable>

    public class quoteRecord
    {
        public String id {get;set;}
        public String name {get;set;}
        public Boolean selected {get;set;}
                
        public quoteRecord(
            String setId,
            String setName,
            Boolean setSelected)
        {
            id = setId;
            name = setName;
            selected = setSelected;
        }
    }


    public List<quoteRecord> getQuotes()
    {
        quoteRecords.clear();
        
        for (quote q : [SELECT id, name
                        FROM quote
                        WHERE opportunityId = : opportunityId])
        {
            quoteRecords.add(new quoteRecord(q.id, q.name, false));
        }
        
        return quoteRecords;
    }


    public List<quoteLineItem> getQuoteLineItems()
    {
        return [SELECT id, quote.name, pricebookentry.product2.name, provisioning_page__c
                FROM quoteLineItem
                WHERE quoteId = : ApexPages.currentPage().getParameters().get('provQuoteId')];
    }

Thank you for any help.
