form the log file as a table - powershell

Question

I have the following code
function ping-test($hosts) {
$conn = [System.Collections.ArrayList]#($hosts)
[int]$hostsamount = $conn.Count
foreach($co in $conn)
{
$check = Test-Connection $co -Count 3 -ErrorAction SilentlyContinue
$zugriffzeit = $check | select ResponseTime | Measure-Object ResponseTime -Average
$avg = [system.math]::Round($zugriffzeit.Average)
$zeit = Get-Date -Format HH:mm:ss
if($check -eq $null)
{
$pcre = Write-Output $co
$pire = Write-Output 'False'
$zure = $null
}
else
{
$pcre = Write-Output $co
$pire = Write-Output 'True'
$zure = Write-Output "$avg ms"
$zure = $zure.Replace(' ','')
}
[void]$re.Add([PSCustomObject] #{PCName=$pcre; PingResult=$pire; Zugriffszeit=$zure; Zeit=$zeit} )
**$log = "Host:{0} Ping: {1} Zugriffszeit: {2} Zeit: {3}" -f $pcre, $pire, $zure, $zeit
$log >> $logpath**
[int]$recount = $re.Count
[int]$eff = $recount - $hostsamount
try {
$re.RemoveRange(0, $eff)
}
catch{
Write-Host $Error
}
}
return $re
}
I use the following code(is in that function)
$log = "Host:{0} Ping: {1} Zugriffszeit: {2} Zeit: {3}" -f $pcre, $pire, $zure, $zeit
$log >> $logpath
the Question is: I want to form a table with the Colums "Host", "Ping", "Zugriffszeit", and "Zeit".
How can I form this table and save as a .txt or .log file somewhere??
Thx for the help

Answer 1

Use the same data as you're outputting!
To export to csv (if you want to re-use the data programmatically later):
$re |Export-Csv $logpath -NoTypeInformation
If you want to ever format it in a nice table again, it's as easy as:
Import-Csv $logpath |Format-Table
If you simply want nicely tabulated output in your log file:
$re |Format-Table |Out-String |Out-File $logfile

Answer 2

#MathiasR.Jessen showed import and export to csv.
But if you are bound to use .txt or .log files (As the aspect of your question says) then use PSCustomObject and Out-File
[PSCustomObject]#{
Host = $pcre
Ping = $pire
Zugriffszeit = $zure
Zeit = $zeit
} | Out-File $logpath
Later import it like:
Get-Content $logpath
