I have set up Jasper Report to be generated into XLS format.

When I click print button, it will show like this :

Then, when I choose "Excel", download pop up will appear and my .xls format will be downloaded. 

Unfortunately, when I open the file, it doesn't generated precisely, there are columns that doesn't fit correctly, like this :

How can I generate *JasperReports*'s report into XLS with correct format and got all my data shown correctly?
