The output of Format-* cmdlets cannot be consumed by anything but Out-File, Out-String, Out-Printer, and Out-Host. This is a common mistake, as described in "The Big Book of PowerShell Gotchas" (powershell.org/wp/ebooks). I suggest reviewing that (it's a free book).
Consider using Select-Object instead. You will need to remove the FormatString and Align directives, as Select-Object does not support those.
