title: To track style changes in Excel 2007/2010 using VBA
body: <p>I need to track the cell style changes in some sheets. I cannot use the buid-in tracking in Excel 2007/2010 because I need to customize something. I tried to track the style change by Workbook_SheetChange but failed. It never fire when I change the cell from one style to another.</p>
  
  <p>Is there any other event that can be used to track the style change? Or any workaround for that?</p>
