从PowerShell 5.1或更高版本开始，您可以使用VT转义序列向单个列添加颜色，但前提是您的控制台支持VT转义序列（例如Windows 10 Fall Creators Update、Linux或Mac，但不支持Windows 8 w/o控制台模拟器（如ConEmu））。
下面是一个在表达式中指定格式的示例，尽管同样可以在ps1 xml文件中使用：

dir -Exclude *.xml $pshome | Format-Table Mode,@{
    Label = "Name"
    Expression =
    {
        switch ($_.Extension)
        {
            '.exe' { $color = "93"; break }
            '.ps1xml' { $color = '32'; break }
            '.dll' { $color = "35"; break }
           default { $color = "0" }
        }
        $e = [char]27
       "$e[${color}m$($_.Name)${e}[0m"
    }
 },Length

和结果输出，请注意，列宽看起来不错，没有多余的空格从转义序列字符。

接受的答案是不正确的，可以对列进行着色。获取条件列颜色的解决方案是使用Write-PSObject。
Here are some wonderful examples带有文档代码和解释。
从上面的资源：

Write-PSObject $servers -MatchMethod Exact -Column "Manufacture" -Value "HP" -ValueForeColor Yellow -ValueBackColor Red -RowForeColor White -RowBackColor Blue;

的数据
我通过a GitHub issue to add color formatting to Format-Table发现了这个，这似乎是PowerShell开发人员希望在某个时候添加的功能。

您可以使用正则表达式对 * 行 * 进行着色.

filter colorize-row{

    Get-Process | Select-Object Id, Name, WS, Responding | foreach {

        # Print 'red' row if WS greater than 100 MB
        if([System.Math]::Round($_.WS/1MB,1) -match "^([0-9]|[0-9][0-9]|[1-9][0-9]?$|^100$)$"){
            [console]::ForegroundColor="white"; $_;
        } else {
            [console]::ForegroundColor="red"; $_;
        }
    }
}

的数据

快速的回答是你不能。可以使用Write-Host与颜色，但没有“输出”发送到格式表。
Write-Host的“输出”是一个副作用，它直接将数据发送到控制台，而不是像标准函数那样将数据返回给调用者。
结合@大卫马丁的评论，这里是a link与一个有趣的模式匹配格式颜色函数。

是的，您可以使用ANSI转义颜色并使颜色具有条件：

Get-Process | Format-Table @{ Label = "PID"; Expression={$_.Id}},
        @{ Label = "Name"; Expression={$_.Name}},
        @{ Label = "RAM (MB)"; Expression={if($_.WS/1MB -gt 100){"$([char]27)[0;31m$([System.Math]::Round($_.WS/1MB, 1))$([char]27)[0m"}else{"$([char]27)[0;32m$([System.Math]::Round($_.WS/1MB, 1))$([char]27)[0m"}}},
        @{ Label = "Responding"; Expression={if($_.Responding -eq $true){"$([char]27)[0;32m$($_.Responding)$([char]27)[0m"}else{"$([char]27)[0;31m$($_.Responding)$([char]27)[0m"}}}

这是一个不同版本的Jason Shirk's answer后，几年来，现在使用PSStyle在PowerShell 7.4

的数据

# Create a dummy data table with three columns: Name, Age, and Occupation
$data = @(
    [PSCustomObject]@{Name = 'Alice'; Age = 25; Occupation = 'Teacher' }
    [PSCustomObject]@{Name = 'Bob'; Age = 30; Occupation = 'Engineer' }
    [PSCustomObject]@{Name = 'Charlie'; Age = 35; Occupation = 'Doctor' }
    [PSCustomObject]@{Name = 'David'; Age = 40; Occupation = 'Lawyer' }
    [PSCustomObject]@{Name = 'Eve'; Age = 45; Occupation = 'Artist' }
)

$PSStyle.Formatting.TableHeader = "$($PSStyle.Foreground.FromRGB(218,112,214))"

$data | Format-Table @{
    Label      = 'Name'
    Expression =
    { switch ($_.Name) {
            { $_ } { $color = "$($PSStyle.Foreground.FromRGB(255,255,49))$($PSStyle.Blink)" } # Use PSStyle to set the color
        }
        "$color$($_.Name)$($PSStyle.Reset)" # Use PSStyle to reset the color
    }
}, @{
    Label      = 'Age'
    Expression =
    { switch ($_.age) {
            { $_ -gt 30 } { $color = "$($PSStyle.Foreground.FromRGB(255,20,147))$($PSStyle.Blink)" } # Use PSStyle to set the color
        }
        "$color$($_.age)$($PSStyle.Reset)" # Use PSStyle to reset the color
    }
}, @{
    Label      = 'Occupation'
    Expression =
    { switch ($_.Occupation) {
            { $_ } { $color = "$($PSStyle.Foreground.FromRGB(152,255,152))$($PSStyle.Blink)" } # Use PSStyle to set the color
        }
        "$color$($_.Occupation)$($PSStyle.Reset)" # Use PSStyle to reset the color
    }

这个例子显示了事件记录的行的交替背景颜色（感谢this post）。根据TimeCreated字段，文本颜色将是蓝色（一个月或更少），黄色（一周或更少）或红色（今天）。请参阅维基百科上的'ANSI转义码'主题以获取颜色转义码。
