title: How to put rich text in a merged cell using xlwt
body: <p>Following up on <a href="https://stackoverflow.com/questions/14149748/format-individual-characters-in-a-single-excel-cell-with-python">an earlier question</a> about a subset of the functionality I need, I'm trying to put rich text in a merged cell of an Excel worksheet created using the xlwt package. I know about <code>sheet.write_merge()</code> and (with the help of that earlier question) I found <code>sheet.write_rich_text()</code> but there doesn't appear to be a way to do both. Excel supports it, so at least in theory it should be possible for xlwt to do it. Is the functionality there and I just haven't found it?</p>
  
  <p>Thanks!</p>
