  <h1>HTML5 Editable Table</h1>
  <p>Through the powers of <strong>contenteditable</strong> and some simple jQuery you can easily create a custom editable table. No need for a robust JavaScript library anymore these days.</p>
  
  <ul>
    <li>An editable table that exports a hash array. Dynamically compiles rows from headers</li> 
    <li>Simple / powerful features such as add row, remove row, move row up/down.</li>
  </ul>
  
  <div id="table" class="table-editable">
    <span class="table-add glyphicon glyphicon-plus"></span>
    <table class="table">
      <tr>
        <th>Name</th>
        <th>Value</th>
        <th></th>
        <th></th>
      </tr>
      <tr>
        <td contenteditable="true">Stir Fry</td>
        <td contenteditable="true">stir-fry</td>
