If you use JSF2.0 and Facelets, you could use <ui:repeat> and <h:dataTable> tags. Make your bean return items grouped in categories. In categories, keep list of items rows. Row is just an array (could be list too).

@ManagedBean
public class Cart {
  List<CategoryItems> getItemsGroupedInCategories() {
    //get items here
  }
}

public class CategoryItems {
  private String categoryName;
  private List<Item[]> itemsRows;
  //constructors, getters/setters
}

Then in JSF XHTML you put:

<ui:repeat value="#{cart.itemsGroupedInCategories}" var="categoryItems">
  <h:dataTable value="#{categoryItems.itemsRows}" var="row" >
    <f:facet name="header">
      <h:outputText value="#{categoryItems.categoryName}" />
    </f:facet> 
    <h:column>
      <h:outputText value="#{row[0]}" />
    </h:column>
    <h:column>
      <h:outputText value="#{row[1]}" />
    </h:column>
    <h:column>
      <h:outputText value="#{row[2]}" />
    </h:column>
  </h:dataTable>
</ui:repeat>
