title: Excel HTML file <br /> not recognised until I click on the cell
body: <p>I'm generating an excel (2010) file with Classic ASP.</p>
  
  <pre><code>&lt;%
  Response.ContentType = "application/vnd.ms-excel"
  %&gt;
  &lt;html xmlns:v="urn:schemas-microsoft-com:vml"
      xmlns:o="urn:schemas-microsoft-com:office:office"
      xmlns:x="urn:schemas-microsoft-com:office:excel"
      xmlns="http://www.w3.org/TR/REC-html40"&gt;
  . . .    
  &lt;table&gt;
    &lt;tr&gt;
      &lt;td&gt;District&lt;br /&gt;9&lt;/td&gt;
    &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>The cell comes out [District9] (with no line break) until I double-click the cell. When I double-click it, the line break is finally recognised and remains so even after I remove the focus from the cell. (as it should)</p>
  
  <p>District<br>&nbsp;&nbsp;&nbsp;&nbsp;9</p>
  
  <p>Should I be doing something else to have Excel open it and recognise the line break automatically?<br>
  (p.s please ignore mso-data-placement:same-cell. I got that one.)</p>
