I already tried to do this... When I use c:forEach, the result is an empty
column (so the nested columns aren't rendered).
<tr:column width="20%"
headerText="#{text['calculationOverview.counters']}">
<c:forEach items="#{row.counters}" var="counter">
<tr:column headerText="#{counter.type.id}">
<tr:outputText value="#{counter.valueString}"/>
</tr:column>
</c:forEach>
</tr:column>
