Question

我想格式化输出表，在第一列上使用左对齐，在所有剩余列上使用右对齐。当我替换$ myobj =“”|选择“Drive”，“PercentFreeSpace”，“DriveSpace”，“FreeSpace” with $ myobj = Format-Table [[“”|选择“Drive”，“PercentFreeSpace”，“DriveSpace”，“FreeSpace”] [-AutoSize]] 我收到了错误。

下面的powershell脚本。

你不希望你的对象成为一个表，你希望它成为一个对象。然后当你去输出时，它将数组格式化为表格。所以请保留$ myObj原样，然后当你去输出时做类似的事情：

"The following Drives are below the $MinFreePercent% Threshold limit: $Drives_Threshold" | out-file $FileDriveSpace
$outarray |FT -Auto | Out-File $FileDriveSpace -append

if($notify -eq 1){
    $scr = gc $FileDriveSpace
