问题 I simply need to perform a very basic for cycle in JSF/ICEFaces, basically rendering column numbers Something like the following pseudo-code for(int i=0; i<max; i++) { <td>#{i}</td> } the <c:forEach> tag iterates over collections, but I don't want to make my backing bean more complex returning a stupid collection of integers.
