title: Syntax for data binding with Index
body: <p>Stuck on what is most likely just a syntax issue.  I want to replace the '1' in 'play1' with the v-for index.</p>
  
  <pre><code>&lt;tr v-for="index in 5"&gt;
    &lt;td&gt;{{player1.round1.play1}}&lt;/td&gt;
    &lt;td&gt;{{player2.round1.play1}}&lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>I tried many variations of {{player1.round1.play + index}} with no success.</p>
