sample usage:
<t:dataTable id="l" forceId="true"
value="#{MyController.myList}"
newspaperOrientation="horizontal"
newspaperColumns="#{MyController.showFoo?7:8}"
Pls see also TOMAHAWK-728 newspaperColumns attribute ignores EL expression.
I provided a patch there but it is has not been applied and 728 has been set to
fixed although it is not working!
