Wrap datatable column text

I am trying to use css to wrap the text for a single datatable column header but it does not seem to work. I read through other answers and have used the same css but to no avail.

The snippet is here:

Any help appreciated!

You should apply css directly to the header. Then you can set the text alignment:
