Get-WMI object exporting IP configuration to HTML only displays System.String[]

Question

Hi,
 I'm trying to customise a powershell script I found in the technet gallery for server inventory by adding reporting information for IP details. The disk sample works perfectly and I can export my data to an HTML file, but the IP address information
I'm struggling with.
The IP information displays:
True
System.String[]
System.String[]
System.String[]
laptop-04
00:DB:DF:0D:84:
I can use the IP powershell ina for loop and display the IP details correctly, but in this format if I want to export it to a HTML it doesn't work, please advise.
$IPInfo = Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter IPEnabled=TRUE -ComputerName $ComputerName | Select-Object -Property [a-z]* -ExcludeProperty IPX*,WINS* |
select DHCPEnabled, IPAddress, IPSubnet, DefaultIPGateway, DNSHostName, MACAddress | ConvertTo-Html -Fragment 
#Logical Disk Information
#the @Name below simply renames the size
$Disk = Get-WmiObject -Class Win32_LogicalDisk -Filter DriveType=3 | 
Select SystemName , DeviceID , @{Name=”size(GB)”;Expression={“{0:N1}” -f($_.size/1gb)}}, @{Name=”freespace(GB)”;Expression={“{0:N1}” -f($_.freespace/1gb)}} |
ConvertTo-Html -Fragment
Thanks in advance...

jrv,
 Many thanks, much appreciated :-)
I've used your format to get the following:
$IPInfo = Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter IPEnabled=TRUE -ComputerName $ComputerName | Select-Object -Property [a-z]* -ExcludeProperty IPX*,WINS* |
select DHCPEnabled, @{N='IPAddress';E={$_.IPAddress -join '|'}}, @{N='IP Subnet';E={$_.IPSubnet -join '|'}}, @{N='Default IP Gateway';E={$_.DefaultIPGateway -join '|'}}, DNSHostName, MACAddress | ConvertTo-Html -Fragment 
QQ - I get the @{N='IPAddress' is used to rename the IP Address, but does the 'E={$_.IPAddress -join '|'}}' do? I can guess it's an express to expand the $_.IPAddress and pipe all the results into a join, but I'm not sure as I've never seen the 'E=' format
before.
@{N='IPAddress';E={$_.IPAddress -join '|'}}
Thanks again
