Powershell Flip-Array Function

You know when you get some output from say Get-ExchangeServer that has load of values and when you output it to HTML it goes off the page and looks pants?  I do quite a bit of this, and thought, can I flip the array, so around.  Yeah baby you can! So here you go.  This v2 with some bugs ironed out.  Enjoy

function Flip-Array([Array]$Array, [String]$key){
  $matrix =@()
  $KeyValue = @()
  $Array | ForEach{$KeyValue += $_.$key}
  $cols = @(); $cols += "Property" ; $cols += $keyValue
  $rows = @(); $array | Get-Member | Where {($_.MemberType -like "*Property") -AND ($_.Name -ne $key)} | ForEach{$Rows += $_.Name}
  $Rows = $Rows | sort unique
  $rows | ForEach{
    $tmpMatrix = "" | Select $cols
    $tmpMatrix.Property = $_
    $Matrix += $tmpMatrix
  }

  ForEach($item in $Array){
    $ItemKey = $item.$key
    ForEach($Row in $Rows){
      $itemvalue = $Item.$Row
      if($itemvalue.GetType.Name -like "MultiValued*"){$itemvalue = $Item.$Row -Join "!#!"}
      ($Matrix | Where {$_.Property -eq $row}).$ItemKey = $itemvalue 
    }
  }
  $matrix = $matrix | sort property -Unique
Return $Matrix
}

$e = get-exchangeserver
$h = Flip-Array $e Name | ConvertTo-Html
$h | out-file .\exchange.html
