SOS: Columnas al exportar de C.Report a Excel

[deivy]

Necesito exportar un crystal report a excel.
He probado de esta forma:

MemoryStream oStream;
oStream = (MemoryStream) report.ExportToStream.CrystalDecisions.Shared.Expo rtFormatType.Excel);
Response.Clear();
Response.Buffer= true;
Response.ContentType="application/vnd.ms-excel";

Response.BinaryWrite(oStream.ToArray());
Response.End();


y de esta otra forma:

ExcelFormatOptions excel = new ExcelFormatOptions();

excel.ExcelUseConstantColumnWidth = false;
excel.ExcelConstantColumnWidth=70;

DiskFileDestinationOptions disk = new DiskFileDestinationOptions();
disk.DiskFileName = "c:\\test.xls";
ExportOptions export = cr.ExportOptions;
export.FormatOptions = excel;
export.ExportFormatType = ExportFormatType.Excel;
export.ExportDestinationType = ExportDestinationType.DiskFile;
export.DestinationOptions = disk;
cr.Export();

El problema es q los campos ocupan varias columnas
COMO REMEDIAR ESTO???


GRACIAS
