title: Browse an array of months with 'ngFor' directive
body: <p>My lack of knowledge in Angular 2 and typescript led me to this issue :</p>
  
  <p>I want a datatable (already imported well) with all the months of the year on abscissa, and some DB objects on the ordinate (this is OK).</p>
  
  <p>I don't know how and where to declare my list of months and how to browse it in my html.
  A this moment, I have this :</p>
  
  <p>Component.ts :</p>
  
  <pre><code>  public months= {
      1:'Janvier',
      2:'Février',
      3:'Avril',
      etc...
      12:'Decembre'
    };
  </code></pre>
  
  <p>Component.html</p>
  
  <pre><code>&lt;td *ngFor="let month of months"&gt;{{month}}&lt;/td&gt;
  </code></pre>
  
  <p>Could you help me making it work (displaying at least a raw of months) and as clean as possible ? I'm pretty sure declaring a list of months directly in the class is not a good thing...</p>
  
  <p>Thank you for reading</p>
