css in DefaultDataTable

[wicketmonkey]

Is there any way that you can apply your own css to datatable. I saw some user 
mentioning inmethod api but that uses its own internal DefaultDataGrid from 
inmethod library . Looks like inmethod implemented everything on it's own. I 
would like to know what would be the easiest way to do it in DefaultDataTable . 
Is there any way i can overide some of the method in PropertyColumn to do that. 
thank you
