Hi,
while developing 2 application I notice a strange layout problem with rich:dataTable with column filtering enabled and the Safari browser.
the css style "white-space: nowrap" into the dr-table-subheadercell class bring layout problem in Safari as you can see in those 2 examples:

I've solved just overriding the value and setting it to "normal" but maybe someone needs the nowrap attribute applied to titles.
