Column height/width config

I am getting the data for DataTables from the server. Some columns contain a lot of text and that is why those columns are having a big height. I would like to make them wider in order to increase the usability. Here is an example(although, without server-side support, but the problem is visible):

I cannot use the "sWidth" property, since I cannot know on which column will the large amount of text be.
