How to show 2 line in one column in datatable?

I have a data table in my application. One column have heavy data which increasing the width of table.

I want to split the data to two or more lines in that column.

I have tried by setting width for that column but data did't split and doesn't show total data.

<p:column headerText="#{msgs['exception.label.exceptionMsg']}" width="200">
         <h:outputText value="#{exception.exceptionMsg}"/>
</p:column>

How can i split the data?
