You can render any element inside the <p:columns> element.

What you want to do is probably render the cell contents differently, depending on the column. You can try something like this :

  //classic rendering (for all cells)
  <h:outputText value="#{car[column.property]}"/>

  //conditional rendering (for 'report' cells only)
  <h:panelGroup rendered="#{column.property == 'report'}">
    <p:commandLink id="MRepShowButton" update=":form1:display" onclick="EditorDialog.show();"  title="Editer le compte rendu">
      <f:setPropertyActionListener value="#{exam}" target="#{dyna.selectedExamen}" />  
      <p:graphicImage id="img1" value="/images/study_Report_icons/Text/0.png" rendered="#{exam.examen.rapport.rapportWrittenState == null}"/>
      <p:graphicImage id="img2" value="/images/study_Report_icons/Text/#{exam.examen.rapport.rapportWrittenState}.png" rendered="#{exam.examen.rapport.rapportWrittenState != null}"/>
    </p:commandLink>
  </h:panelGroup>
