title: rowspans and colspans in html email
body: <p>Can rowspans and colspans be safely used when designing table-based HTML emails?</p>
  
  <p>I have been told that they don't display correctly in Outlook 2007 and that tables must be nested in order to provide different size cells for layout.</p>
  
  <p>Can anybody help or provide any links? Thanks</p>
