                             paginator="true" rows="10"  pageLinks="10"  
                             paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks}   
                             {NextPageLink} {LastPageLink} Registros por página: {RowsPerPageDropdown}"  
                             rowsPerPageTemplate="5,10,15,20" lazy="true">

                    <p:column headerText="" style="width:5%;">  
                    </p:column>

                    <p:column id="cod" filterBy="#{titcadusu.cpfusu}" 
                              
                              headerText="Cpf" 
                              filterStyle="max-width: 90px; min-width: 70px;font-size:10px;font-family:arial,Tahoma,Sans-serif;"
                              filterMatchMode="contains"                                 
                              style="width:15%; font-size:11px;font-family:arial,Tahoma,Sans-serif; text-align: center;"
                              >
