I added sortBy="#{v.prop}" to rich:column but header is still not sortable.

What should I do to make column sortable?

Hello, you can do as explained in the showcase :-)

http://richfaces-showcase.appspot.com/richfaces/component-sample.jsf?demo=dataTable&sample=tableSorting&skin=blueSky

Or try with javascript :

<h:outputLink value="javascript:#{rich:component('mytable')}.sort('mycolumn');">MyLabel</h:outputLink>

Best regards,
