My Question

How can i avoid repetition of table display twice? I want the data to be displayed only one time.
As you see in the above screen shots, I don't want the data to be displayed twice.
Solution
You have put your table component into the detail band. The detail band is repeated for every record in the dataset. You have two records, so your table is repeated twice; If you had more data, you would get many more repetitions.
You could get rid of the table component completely, putting each columnHeader element from the table into a <columnHeader> band, and each detailCell element into a <detail> band. Doing this should preserve the behaviour of the table component without repeating it. See http://community.jaspersoft.com/wiki/designing-report for an example of this.
Alternatively, you could simply move your table component into a different band that doesn't get repeated (e.g. <summary>).
