从脚本与cli运行时，Powershell命令没有输出
在脚本中运行时，这一个命令不会将输出写入屏幕，但在PowerShell ISE cli中执行时，该命令可以工作：
$toptenseverity = $csvData | select Severity, Title -Unique | sort Severity -Descending | select -First 11
$toptenseverity
码：
Write-Host "`r`nTop 10 most severe vulnerabilities:"
$toptenseverity = $csvData | select Severity, Title -Unique | sort Severity -Descending | select -First 11
$toptenseverity
Write-Host "Trying again to write output of toptenseverity using write host toptenseverity:"
Write-Host $toptenseverity
Write-Host "Trying again to write output of toptenseverity using write output toptenseverity:"
Write-Output $toptenseverity
输出：
Generating P1 report. Please wait...
Total P1 count: 352
Severity 5 total: 11
Severity 4 total: 16
Severity 3 total: 325
Top 10 most severe vulnerabilities:
Trying again to write output of toptenseverity using write host toptenseverity:
@{Severity=5; YouDon'tNeedToKnowThis} @{Severity=4; Title=YouDon'tNeedToKnowThis} @{Severity=4; Title=YouDon'tNeedToKnowThis
} @{Severity=4; Title=YouDon'tNeedToKnowThis} @{Severity=4; Title=YouDon'tNeedToKnowThis}
Trying again to write output of toptenseverity using write output toptenseverity:
当我从PS ISE中的cli运行它时，我得到这个输出：
Severity Title
-------- -----
5 YouDon'tNeedToKnowThis
4 YouDon'tNeedToKnowThis
4 YouDon'tNeedToKnowThis
4 YouDon'tNeedToKnowThis
4 YouDon'tNeedToKnowThis
使用：
Write-Output $toptenseverity | Format-Table
这迫使对象被格式化为一个表格，这是ISE中发生的事情（默认情况下）
