How to merge cells in crystal reports

Question

Hi All,

I've created a sample crystal report in table format using VS2005. That report gives employee details in a particular building by taking the building as a parameter. The report is working fine, but i want to change the view of the report. Suppose for building1 there are 4 employees and my report is coming like this..(shown below).

Building #	Employee Id	Employee Name	Project	Address
1	2346	Emp1	FG	HYD
1	6543	Emp2	FGK	HYD
1	6546	Emp3	HJ	DEL
1	6525	Emp4	HK	CHN

Now i want to change the above report view similar to what is given below.

Building #	Employee Id	Employee Name	Project	Address
1	2346	Emp1	FG	HYD
	6543	Emp2	FGK
	6546	Emp3	HJ	DEL
	6525	Emp4	HK	CHN

I mean to say...i want the duplicate cells to be merged and should be displayed as one..(building #: 1 and the Address Hyd)

Building '1' is repeating for all the rows in the first table. i want the 4 cells to be merged and should be displayed as given in the second table. 

Can anyone plz tell me how to do this?

Thanks in Advance,

Venky
