WPF Table Multiple Row Header

Question

How can i achieve this multiple row header in WPF table?

Example:

ID     Name         Age      Gender
       City         Phone 1   
       Address 1    Phone 2
       Address 2
------------------------------------
1      Justin       30        M
       L.A.         1000000
       St.Add 1     2000000
       St.Add 2
2      Monica       25        F
       Salt Lake    5000000
       St.Add 8     6000000
