title: dynamical change td width with js
body: <p>I need to change the width of a td using javascript.  The value of the width will be pulled in and then I need to multiple it to get a percentage.  I just need to know how to write the js so far I have got to here but it is not working</p>
  
  <pre><code>&lt;script language="JavaScript"&gt;
  var divWidth = 66*0.4;
  
  document.write("&lt;td width="+divWidth+"&gt;");
  
  document.getElementById("myRow").write("&lt;td width="+divWidth+"&gt;");
  
  &lt;/script&gt;
  
  
  &lt;table&gt;
  &lt;tr&gt;
      &lt;td id="myRow"&gt;&lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
