this issue have already been solved in JIRA
https://jira.jboss.org/jira/browse/RF-3786
there is still a problem with the extra th
<rich:dataTable value="#{capitalsBean.capitals}" var="capital">
<rich:column>
<f:facet name="header">Capital Name</f:facet>
</rich:column>
<rich:column>
<f:facet name="header">Property Name</f:facet>
</rich:column>
<rich:column>
<f:facet name="header">Property Value</f:facet>
</rich:column>
<rich:subTable value="#{capital.detailList}" var="detail">
<rich:column />
<rich:column>
<h:outputText value="#{detail.key}" />
</rich:column>
<rich:column>
<h:outputText value="#{detail.value}" />
</rich:column>
</rich:subTable>
</rich:dataTable>
the example to this problem is in richfaces live demo as refered
this dataTable in the above is using <rich:columnGroup>
it is fine when using the property
but the dataTable losses some of its property like ---- sortBy , which is one of the features in dataTable
if this is the case then is there any solution to this that i will retain the like ---- sortBy and doesnot face the problem of of extra
if <rich:columnGroup> is the only solution please comment on this
and another way i can use <rich:subDataTable> and donot get the extra
for the use i have taken a screen shot of the view and posting it here
the screenshot is not releated to the example code i have given above but it follows the same pattern
