The scrollableDataTable configuration below (RichFaces 3.3.0) generates a table with 3 columns instead of 2 columns as expected:
[<rich:scrollableDataTable value="#{AccountsPhysicalList.accountsList}" var="sel" id="table"
height="200px" width="300px" selection="#{dataTableScrollerBean.selection}"
sortMode="multy">
<rich:column sortable="true" id="accountName">
<rich:toolTip value = "The Make of the car" for="accountName"/>
<f:facet name="header"><h:outputText value="Make" /></f:facet>
<h:outputText value="#{sel.accountName}" />
</rich:column>
<rich:column id="accountLink">
<f:facet name="header"><h:outputText value="Model" /></f:facet>
<h:outputText value="Details" />
</rich:column>
</rich:scrollableDataTable>
third fake column is needed because table has resize feature. You could hide it via CSS.
