powershell

I have a AD query to export all group membership , that works perfectly.

Get-QADUser -searchRoot $OuDomain -SizeLimit 0 | Select-Object dn, sAMAccountName, @{Name="Groups";Expression={(Get-QADMemberOf $_ | Select-Object -expandProperty Name) -join
";"}} | export-csv $FilePath | Sort-Object SamAccountName

Result -

DN  SamAccountName  Groups
abc.com     user1      group1;group2;group3

How to export the above result sin column ....like user1 group1
                                                   user1 group2
                                                   user1 group3

DN  SamAccountName  Groups
abc.com  user1          group1
         user1          group2
         user1          group3

I want the output in  columns , presently I am getting all export in one row.

Thanks for your help.
