If I have a loop, let’s say:

\<% for user in @users %\>

 \<%= link\_to "#{user.his\_uid}", :action =\> 'show', :id =\> user %\> \<%= link\_to "#{user.his\_uid}", :action =\> 'show', :id =\> user %\> \<% end %\>

How can I get the second #{user.his\_uid} to be the second object in  
the list? Is there a method for this (object.next) or a special way of  
making two columns tables?

Thanks in advance,  
LP

Are you after something like this?

\<% for user in @users %\> \<%= link\_to user.his\_uid, :action =\> 'show', :id =\> user %\> \<% end %\>
