Hi,
I have a problem with this code:
<rich:dataTable ...> <rich:column> ... </rich:column> <rich:column> ... </rich:column> <rich:column> ... </rich:column> <rich:subTable> <rich:column> ... </rich:column> <rich:column> ... </rich:column> <rich:column> ... </rich:column> </rich:subTable> </rich:dataTable>
Show please real code and describe the thing you wanted. Have you seens that in our live example there are some span attributes in order to create needed structure...
