title: how to display the number of filtered rows outside table definition?
body: <p>I have implemented a filter for my <code>ngtable</code>. Trying to display the number of filtered items like this:</p>
  
  <p>How to display <code>nr</code> of filtered rows here? Outside the table definition?</p>
  
  <p><code>{{filtered.length}}</code> result(s) matching the filter</p>
  
  <pre><code>&lt;table ng-table="tableParams" class="table"&gt;
                      &lt;tr ng-repeat="account in filtered =($data  | filter:search.accountName | filter:search.id)"&gt;
                        &lt;td&gt;{{filtered.length}}&lt;/td&gt;
                        &lt;td data-title="'id'"&gt;
                          {{account.account.accountId.id}}
                        &lt;/td&gt;
                        &lt;td data-title="'name'"&gt;
                          {{account.account.accountName}}
                        &lt;/td&gt;
  
                      &lt;/tr&gt;
  &lt;/table&gt;
