title: How to compare Excel files in Java with DBUnit
body: <p>I need to compare two Excel files to find any kind of content difference.
  Format/Color/Font differences are not to be considered.
  I followed the solution found at <a href="https://stackoverflow.com/questions/866346/easiest-way-to-compare-two-excel-files-in-java">this post</a> but it's based on the DBUnit XlsDataSet class.
  This class works on the assumption that the Excel file has a specific structure:
  <em>the first row should represent the table header</em>. This is not always true in my environment.
  Table header might start at cell C4, for instance.</p>
  
  <p>However, I'd like to stick to DBUnit as it provides great support.
  Is anyone aware of how to configure where the table header starts in XlsDataSet class?</p>
  
  <p>Thanks and regards</p>
