Thanks to SimonSez suggestion i managed to solve this issue with the help of some css.
Here is the solution i used:
<p:column sortBy="#{serviceLevel.titleAndDescription}">
<f:facet name="header">Description: </f:facet>
<h:outputText style="font-weight:bold; display: block;" value="Title: " />
<h:outputText style="display: block;" value="#{serviceLevel.title}" />
<h:outputText style="font-weight:bold; display: block; padding-top: 20px;" value="Description: " />
<h:outputText value="#{serviceLevel.description}" />
</p:column>
