title: Django_tables2: CSS isn't working even though it's registered
body: <p>I copied the screen.css that has the paleblue class shown in the example on the django_tables2 website.</p>
  
  <p>I placed it in my application in the static/css folder and when I call it from my .html it finds it. In the header I placed the following:</p>
  
  <pre><code>&lt;link rel="stylesheet" href="{{ STATIC_URL }}css/screen.css" /&gt;
  </code></pre>
  
  <p>Now, in my tables.py module I have this:</p>
  
  <pre><code>import django_tables2 as tables
  class TipPredmetaTable(tables.Table):
  class Meta:
      model = models.TipPredmeta
      attrs = {'class': 'paleblue'}
  </code></pre>
  
  <p>In my views.py I have this:</p>
  
  <pre><code>def tippredmeta(request):
      queryset = TipPredmeta.objects.all()
      table = TipPredmetaTable(queryset)
      RequestConfig(request).configure(table)
      return render_to_response('azuriranje/tabela.html', {"table": table}, context_instance=RequestContext(request))
  </code></pre>
  
  <p>When I open the page in Mozzila and hit Ctrl+U I can clearly see the following:</p>
  
  <pre><code>&lt;div class="table-container"&gt;&lt;table class="paleblue"&gt;&lt;thead&gt;&amp;#32;&lt;tr&gt;...
  </code></pre>
  
  <p>My .html is exactly the same as on the django_tables2 website, my STATIC_URL is defined, the staticfiles app is enabled. What am I doing wrong?</p>
