title: Binding function with parameters in html class in Vue
body: <p>I have html element:</p>
  <pre><code>&lt;div style=&quot;grid-column: span 1&quot;&gt;
  </code></pre>
  <p>I would like to use function to determine span size:
  I try something like this, but it doesn't render.</p>
  <pre><code>:style=&quot;{ 'grid-column: span': getColumnSize('string') }&quot;
  </code></pre>
  <p>what is correct syntax?</p>
