title: Multiline text in Excel cells
body: <p>I'm trying to write multiline text to excel cells.</p>
  
  <pre><code>cell.setCellValue("line1 \n line2");
  </code></pre>
  
  <p>But when I open the document, I see only one line until I double-click it for editing, then it becomes two-lined. Why is it so? Thanks</p>
