以下代碼能夠將背景更改為某個單元格，但是我需要將背景顏色更改為整行。

這是一種方法嗎？

Add-Type -AssemblyName System.Xml.Linq

# Get the running processes to x(ht)ml
$xml = [System.Xml.Linq.XDocument]::Parse( "$(Get-Process | ConvertTo-Html)" )

# Find the index of the column you want to format:
$wsIndex = (($xml.Descendants("{http://www.w3.org/1999/xhtml}th") | Where-Object {             $_.Value -eq "WS" }).NodesBeforeSelf() | Measure-Object).Count

# Format the column based on whatever rules you have:
switch($xml.Descendants("{http://www.w3.org/1999/xhtml}td") | Where {     ($_.NodesBeforeSelf() | Measure).Count -eq $wsIndex } ) {
{200MB -lt $_.Value } { $_.SetAttributeValue( "style", "background: red;"); continue } 
{20MB  -lt $_.Value } { $_.SetAttributeValue( "style", "background: orange;"); continue    } 
{10MB  -lt $_.Value } { $_.SetAttributeValue( "style", "background: yellow;"); continue   } 
 }
 # Save the html out to a file
$xml.Save("c:\procs2.html")

# Open the thing in your browser to see what we've wrought
ii c:\procs2.html

此處的邏輯（可行的）解決方案是獲取循環中每個td單元的父元素，即整個行（ tr ）。

替換三個：

$_.SetAttributeValue(

同

$_.Parent.SetAttributeValue(

您應該花一些時間來實際學習PowerShell，也許需要一點HTML並通過Google進行搜索。 如果您搜索了XDocument的Descendants方法，則將看到它返回一個XElement ，MSDN表示該元素具有Parent屬性。

更新：這是您的腳本，其中包含我在三個位置的單個更新。 它在這里完美工作。 整行變色。
