title: How to bind title attribute value in ng-table
body: <p>I am using ng-table to display all values in a table view. Message to be displayed in remarks column (last column of the table) is huge. So, I am displaying few character. When user hovers over the cells I want to show the entire message in a tool-tip. I tried to set it in title attribute, but it's not working.</p>
  
  <p>Sample code : <a href="http://plnkr.co/edit/I4nCTNhMfxgbBX7Zjxs9?p=preview" rel="noreferrer">http://plnkr.co/edit/I4nCTNhMfxgbBX7Zjxs9?p=preview</a></p>
  
  <pre><code>&lt;table ng-table="tableParams" class="table"&gt;
          &lt;tr ng-repeat="doc in $data"&gt;
          &lt;td data-title="'#'" sortable="doc_name"&gt;{{$index + 1 }}&lt;/td&gt;
          &lt;td data-title="'Visa Type'" sortable="'type'"&gt;{{doc.type}}&lt;/td&gt;
          &lt;td data-title="'Country'" sortable="'country'"&gt;{{doc.country}}&lt;/td&gt;
          &lt;td data-title="'Starting Date'" sortable="'start_date'"&gt;{{doc.start_date}}&lt;/td&gt;
          &lt;td data-title="'Expired Date'" sortable="'end_date'"&gt;{{doc.end_date}}&lt;/td&gt;
          &lt;td data-title="'Remarks'" sortable="'remarks'" title="{{doc.remarks}}"&gt;
          {{doc.remarks | limitTo: 15 }} {{doc.remarks.length &gt; 15 ? '...' : ''}}
          &lt;/td&gt;
          &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>Please suggest me how to show tool-tip using HTML title attribute. </p>
