I'm sorry walter but I don't really understand what you said, but the
code to display my table is :

<% @defautrec.each do |n| %> <!--Loop to display-->
<tr>
<td><%= n.nomdefaut.nom_defaut%></td>
<td><%= n.repere%></td>
<td><%= link_to controller: "pages", action: "ajouter" do%><button,
class="btn btn-mini btn-success">Ajouter</button><%end%></td>
</tr>

But the in the methode ajouter how can I have something like
@myvariable=n or @myvariable=@defautrec[i] where I is the current line
of the table?
