title: Restrict the display of a table on angular 4
body: <p>please can someone help me to control the display of my table?
  I explain myself... here is my code:</p>
  
  <pre><code>    &lt;div class="table-responsive"&gt;
              &lt;table class="table table-hover" id="customers"&gt;
                  &lt;thead&gt;
                      &lt;tr&gt;
                          &lt;th&gt;Client N°&lt;/th&gt;
                          &lt;th&gt;Nom&lt;/th&gt;
                          &lt;th&gt;Prénom&lt;/th&gt;
                          &lt;th&gt;Adresse&lt;/th&gt;
                          &lt;th&gt;Date de Naissance&lt;/th&gt;
                          &lt;th&gt;Téléphone&lt;/th&gt;
                          &lt;th&gt;Ajoute Par&lt;/th&gt;
                      &lt;/tr&gt;
                  &lt;/thead&gt;
                  &lt;tbody&gt;
                      &lt;tr *ngFor="let c of clients" class="table-active" style="cursor: pointer;"&gt;
                          &lt;td&gt;{{c.id}}&lt;/td&gt;
                          &lt;td&gt;{{c.nom}}&lt;/td&gt;
                          &lt;td&gt;{{c.prenom}}&lt;/td&gt;
                          &lt;td&gt;{{c.adresse}}&lt;/td&gt;
                          &lt;td&gt;{{c.date_naissance}}&lt;/td&gt;
                          &lt;td&gt;{{c.portable}}&lt;/td&gt;
                          &lt;td&gt;{{c.user_id}}&lt;/td&gt;
  ...
  </code></pre>
  
  <p>this code allows me to display all my clients from the database. But i want to display now every clients whose <strong>user_id</strong> equals <strong>1</strong> for example.</p>
  
  <p>Hoping i have made myself clear, can someone please tell if it is possible in <strong>angular 4 HTML</strong>? if it is, please can you tell me how? i think i'm gonna use like <strong>NgIf</strong> but i'm not sure.</p>
  
  <p>Thanks in advance.</p>
