title: Create Excel file with style tag using OpenXmlWriter SAX
body: <p>I am trying to write an Excel Xlsx spreadsheet with styling using OpenXmlWriter (SAX).</p>
  
  <p>I am able to create the file with rows and columns (populate them as strings).
  I am looking for a simple code on how to make the first row (header) with bold font.</p>
  
  <p>I do not have a template file to start with as the file will be dynamic.</p>
  
  <p>I found a few articles on how to add WorkbookStylesPart, but they are all using the DOM. As i need to write large number of rows, the DOM will not work for me. </p>
  
  <p>Could anyone point me at the right direction?
  Simple code to add a header row as bold when using WriteStartElement and OpenXmlAttribute.</p>
  
  <p>Thanks, odansky</p>
