Error When Adjust Width in Custom Table Headers "The width key is not valid"

Question

I tried to custom headers for a table of MAC Addresses. I used the following expression and it worked fine.
Get-WmiObject win32_networkadapterconfiguration -Filter "DHCPEnabled=True" | Select-Object @{Expression={$_.DNSHostname};Name="Workstation"},@{Expression={$_.Description};Name="Adapter"}, @{Expression={$_.MACAddress};Name="MAC"}
When I tried to adjust the width of the columns by including that in the Custom Headers I got an error.
Get-WmiObject win32_networkadapterconfiguration -Filter "DHCPEnabled=True" | Select-Object @{Name="Workstation";width=25;Expression={$_.DNSHostname}},@{Name="Adapter";Expression={$_.Description}},@{Name="MAC";Expression={$_.MACAddress}}
Select-Object : The width key is not valid.

Answer 1

You have a couple of useful options:
#1
Get-WmiObject win32_networkadapterconfiguration -Filter 'DHCPEnabled=True' |
Select-Object @{E={$_.DNSHostname};N="Workstation"},
@{E={$_.MACAddress};N="MAC"},
@{E={$_.Description};N="Adapter"} |
Format-Table -Auto
#2
Get-WmiObject win32_networkadapterconfiguration -Filter 'DHCPEnabled=True' |
Format-Table @{N="Workstation";W=25;E={$_.DNSHostname}},
@{N="MAC";W=18;E={$_.MACAddress}},
@{N="Adapter";E={$_.Description}}
¯\_(ツ)_/¯
