title: Adding new line in excel cell generated via html
body: <p>I'm trying to generate an excel file using html  in php and responding with an excel Content-type. Everything works fine except new lines within a cell  . They are not preserved.
  I've tried <strong>&amp;#13 ;&amp;#10 ; \r\n ,chr(13).chr(10)</strong> and it didn't work.
  I'm trying to get the same result from <strong>alt + enter</strong> from microsoft Excel .</p>
  
  <p>I am generating in a cell content like:</p>
  
  <pre><code> http:\\www.example.com\blah
   (Link)
   http:\\www.example.com\blah2
   (Event) ...
  </code></pre>
  
  <p>these have to be in a single cell  and also converting the link text to hyperlinks would be great :).</p>
