Display the difference of excel columns with PowerShell : I would like to get the difference in the columns in as a table but I only can do a comparison with two columns and it doesn't display all the columns. I need to see in which column the cell is not present in the fisrt column.

the script:

    $x = Import-Csv .\test1.csv -Delimiter ';'
    Compare-Object -ReferenceObject $x.ComputerName -DifferenceObject $x.OtherComputerName

the file:

    ComputerName	   OtherComputerName	OtherComputer	AndAgain
    infra-1	           infra-852	        infra-2	        infra-99
    infra-98	       infra-85	            infra-44	    infra-23
    infra-5	           infra-8	            infra-1	        infra-10
    infra-2	           infra-55	            infra-8	        infra-70
    infra-62	       infra-5	            infra-852	    infra-5
