body: <p>I am using Yexcel - YII plugin that is a wrapper for PHPEXcel for a web application that need to read and parse different excel files.</p>
  
  <p><a href="http://www.yiiframework.com/extension/yexcel/" rel="nofollow">http://www.yiiframework.com/extension/yexcel/</a></p>
  
  <p>I am able to read and use the data in excel files that are single means they have only 
  one sheet but when it comes to reading other sheets in same excel file then i cannot read those because it gives me error.Using PHPExcel we can set active sheets and read
   like this </p>
  
  <p><code>$objPHPExcel-&gt;setActiveSheetIndex(0); // first sheet</code> </p>
  
  <p>but how can we do this using YII's yexcel plugin? </p>
  
  <p>Because when i call this function with yexcel object it gives me error</p>
  
  <pre><code> Fatal error: Call to undefined method Yexcel::setActiveSheetIndex()
  </code></pre>
  
  <p>Issue: How to access all sheets in an Excel file.</p>
  
  <p>Any help, guidance in right direction is much appreciated.</p>
