HTML邮件中的颜色代码单元格基于标准

我有一个简单的脚本来检查远程服务器上的磁盘空间，它有一个简单的输出格式，如下所示

enter image description here

我想做的是根据各个单元格对各个单元格进行颜色编码。具体来说，如果任何驱动器上的可用空间小于300，我想让单元格为红色。根据PowerShell Send-MailMessage以HTML格式发送的结果，最简单的方法是什么？

以下是我从远程服务器收集数据的代码：

function Set-AlternatingRows {
    [CmdletBinding()]
    Param(
        [Parameter(Mandatory,ValueFromPipeline)]
        [string]$Line,

        [Parameter(Mandatory)]
        [string]$CSSEvenClass,

        [Parameter(Mandatory)]
        [string]$CSSOddClass
    )
    Begin {
        $ClassName = $CSSEvenClass
    }
    Process {
        if ($Line.Contains("<tr><td>")) {
            $Line = $Line.Replace("<tr>","<tr class=""$ClassName"">")
            if ($ClassName -eq $CSSEvenClass) {
                $ClassName = $CSSOddClass
            } else {
                $ClassName = $CSSEvenClass
            }
        }
        return $Line
    }
}

foreach ($Item in $InputCSV) {
    Write-Host "Checking $($Item.Server) now"
    $ShortDate = (Get-Date).ToString('MM/dd/yyyy')

    $Ping = PingEM $Item.Server

    ### Check if server is online before proceeding
    if ($Ping -eq "Online") {
        Write-Host "$($Item.Server) is Online" -ForegroundColor Green

        $FreeSpaceAll = Get-WmiObject Win32_LogicalDisk -filter "DriveType=3" -Computer $($Item.Server) |
                        Select SystemName, DeviceID, VolumeName,
                            @{Name="Total Size (GB)";E={"{0:N1}" -f($_.Size/1gb)}},
                            @{Name="Free Space (GB)";E={"{0:N1}" -f($_.Freespace/1gb)}}
        $FreeSpaceC = $FreeSpaceAll | Where {$_.DeviceID -eq "C:"}  | Select -expand "Free Space (GB)"
        $FreeSpaceD = $FreeSpaceAll | Where {$_.DeviceID -eq "D:"}  | Select -expand "Free Space (GB)"
        $FreeSpaceE = $FreeSpaceAll | Where {$_.DeviceID -eq "E:"}  | Select -expand "Free Space (GB)"
    } # Ping

    $outarray += New-Object PsObject -Property @{
        Server = $Item.Server
        FreeSpaceAll = $FreeSpaceAll
        FreeSpaceC = $FreeSpaceC
        FreeSpaceD = $FreeSpaceD
        FreeSpaceE = $FreeSpaceE
        PingResults = $Ping
    } # OutArray New-Object
} # For

$Head = Get-Content "$Dir\CSS.txt"
$Pre = "This email contains info on C/D/E free space on remote servers<br>    <br>" 
$Pre += "The below report data is available in Excel .CSV format $Link1.     After 7 days, the reports will be moved $Link2 <br><br>"

$Output = $OutArray |
          Select Server, PingResults, @{E={$_.FreeSpaceC};Label="Free Space C: (GB)"},
              @{E={$_.FreeSpaceD};Label="Free Space D: (GB)"},
              @{E={$_.FreeSpaceE};Label="Free Space E: (GB)"} |
    ConvertTo-Html -Head $Head -PreContent $Pre -As Table | Set-AlternatingRows -CSSOddClass odd -CSSEvenClass even |
    Out-String

我写了这个，所以它通常做你想要的。它已经设置为与HTML表和免费中继服务器电子邮件提供商一起使用。此脚本采用一个您可以在顶部指定的文本输入文件。此文本文件将包含您要在其自己的行上检查的所有服务器名称。以下示例。如果您想使用自己的电子邮件提供商，则可以替换所有smtp信息。否则，它需要管理员权限才能成功运行。可以在指定$cred的脚本顶部输入这些凭据。您还需要更改$servers变量以指向要检查的服务器名称列表。它目前只选择C驱动器，但您可以轻松编辑它，也可以为ping结果添加一列。

C：\ temp \ servers.txt

的示例 
hqdc01
hqdc02
hqdc03
hqfile01
hqfile02
hqmail01
