title: jasper not formatting excel data types
body: <p>I have a Jasper Report which seems to be exporting fine in all formats except Excel. </p>
  
  <p>The below sample is of a column that should be formatted as currency but shows incorrectly. </p>

  <p>Here are the jasper properties i'm using...</p>
  
  <pre><code>out = new FileOutputStream(file);
  JExcelApiExporter exporterXLS = new JExcelApiExporter();
  
  exporterXLS.setParameter(JRXlsExporterParameter.JASPER_PRINT, print);
  exporterXLS.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE, Boolean.TRUE);
  exporterXLS.setParameter(JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE);
  exporterXLS.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);
  exporterXLS.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_COLUMNS, Boolean.TRUE);
  exporterXLS.setParameter(JRXlsExporterParameter.CREATE_CUSTOM_PALETTE, Boolean.TRUE);
  exporterXLS.setParameter(JRXlsExporterParameter.IS_COLLAPSE_ROW_SPAN, Boolean.FALSE);
  exporterXLS.setParameter(JRXlsExporterParameter.IS_IGNORE_CELL_BORDER, Boolean.TRUE);
  exporterXLS.setParameter(JRXlsExporterParameter.IS_IGNORE_GRAPHICS, Boolean.FALSE);
  exporterXLS.setParameter(JRXlsExporterParameter.OUTPUT_STREAM, out);
  
  exporterXLS.exportReport();
  </code></pre>
  
  <p>I've tried both Jasper 4.0 and 4.5.  I think it has to do with a dependency but i'm not sure. </p>
