Question

Look at the behavior of my table, I want the rows of the email field to appear inside the email field, and not as shown in the image ...

Can anybody help me?

Answer 1

use <ui:repeat> on your email list and print them inside the email column.

 <ui:repeat var="email" value="#{user.emailList}"> #{email} <br/> </ui:repeat>
