title: How to validate table row data with Angular?
body: <p>I have <code>table</code> with <code>ng-repeat</code> for table rows. I want to make inline editing and validation of data from single row, but it is impossible to use <code>form</code> or <code>ng-form</code> inside table. 
  For inline editing I use inputs with <code>ng-show</code> inside <code>td</code>.
  So, I have two questions: </p>
  
  <ol>
  <li><p>Is it correct approach for inline editing? (using hidden inputs
  inside td).</p></li>
  <li><p>How can I validate data from row?</p></li>
  </ol>
  
  <p><strong>Update</strong>: I want for table row something like "form submitting" and add error class for table cells with wrong data.</p>
  
  <p>I'm new to angular.</p>
