ForEach循環生成單個HTML表格

Question

下面是我用來檢查不同文件夾，檢查最近日誌文件，然後報告最近3個時間戳（用[表示）的代碼的簡化版本。

$LogLocations = "C:\Powershell\Test\Scenario1", 
       "C:\Powershell\Test\Scenario2" 

$style = @" 
<style>BODY{font-family: Arial; font-size: 10pt;} 
TABLE{border: 1px solid black; border-collapse: collapse;} 
TH{border: 1px solid black; background: #dddddd; padding: 5px; } 
TD{border: 1px solid black; padding: 5px; } 
</style> 
"@ 

$body = "" 

foreach ($logpath in $LogLocations) { 
    $log = Get-ChildItem -Path $logpath | 
      sort LastWriteTime | 
      select -ExpandProperty FullName -Last 1 
    $text = Get-Content -Path $log | 
      Select-String -SimpleMatch "[" | 
      select Line -Last 3 
    $body += ($text | 
      select Line | 
      ConvertTo-Html -Body "<p>Timestamps of 3 most recent files processed $log</p>" -Head $style | 
      Out-String) 
} 

$emailbody = ConvertTo-Html -PostContent $body | Out-String 
$subject = "Processing Logs Error Checking at " + (Get-Date -Format g) 

Send-MailMessage -From "xxxxxxxxx" -To "xxxxxxxxx" -Subject $subject -Body $emailbody -BodyAsHtml -SmtpServer "xxxxxxxxx" 

結果我得到的是：

Timestamps of 3 most recent files processed C:\Powershell\Test\Scenario1\20160520163102.txt 
* 
[05/21/2016 00:37:52] 
[05/21/2016 00:37:52] 
[05/21/2016 00:37:52] 
Timestamps of 3 most recent files processed C:\Powershell\Test\Scenario2\20160524142045.txt 
* 
[05/24/2016 14:38:48] 
[05/24/2016 14:38:51] 
[05/24/2016 14:38:51]

這是罰款。我得到我想要的信息，只是格式不是最好的。我試圖找到一種方法將結果放在同一個表中，但無法讓代碼正常工作，我會得到錯誤，沒有結果，或可怕的格式化結果。

任何想法？我正在沿着嵌套當前foreach聲明在另一個foreach聲明中的表格列的路線。

如果您不想要多個表，請不要創建多個表。

$emailbody = $LogLocations | ForEach-Object { 
    $dir = $_ 
    Get-ChildItem $dir | 
     Sort-Object LastWriteTime | 
     Select-Object -Last 1 | 
     Get-Content | 
     Where-Object { $_ -like '*[*' } | 
     Select-Object -Last 3 @{n='File';e={$dir.FullName}}, 
      @{n='Timestamp';e={$_}} 
} | ConvertTo-Html -Head $style
