How to get the JasperReports into Excel format wit

In ireportDesigner 5.6.0, when I set "internal Preview" as "XLS Preview",it is getting the report with proper alignment. The image is given below:

When I integrated the report into Eclipse project and run on server, it is getting mis-aligned as shown:

Code in Eclipse is:

Remove at least parameter:

exporter.setParameter(JRXlsExporterParameter.IS_COLLAPSE_ROW_SPAN,Boolean.TRUE)

and note that JRXlsExportParameter is deprecated the correct way from version 5.6 is

JRXlsExporter exporter = new JRXlsExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(xlsReport));

SimpleXlsReportConfiguration configuration = new SimpleXlsReportConfiguration();
configuration.setOnePagePerSheet(true);
configuration.setDetectCellType(true);
configuration.set //The other properties you like to set
exporter.setConfiguration(configuration);
exporter.exportReport();
