Question

我想在表中的列中获得差异，但我只能与两列进行比较，并且它不会显示所有列。我需要查看第一列中单元格不在哪一列。

文件：

ComputerName  OtherComputerName  OtherComputer  AndAgain

infra-1       infra-852          infra-2        infra-99
infra-98      infra-85           infra-44       infra-23
infra-5       infra-8            infra-1        infra-1
infra-2       infra-55           infra-8        infra-70
infra-62      infra-5            infra-852      infra-5

目前的结果：

ComputerName  OtherComputerName  OtherComputer  AndAgain
------------  -----------------  -------------  --------

我想在PowerShell中得到这个结果：

ComputerName  OtherComputerName  OtherComputer  AndAgain
------------  -----------------  -------------  --------
infra-1       infra-852                         infra-99
infra-98      infra-85           infra-44       infra-23
infra-5       infra-8
infra-2       infra-55           infra-8        infra-70
infra-62                         infra-852

修改

运行此代码时，我也遇到了一些错误。

剧本：

$csv = Import-Csv .\test1.csv -Delimiter ';'

$ref = @($csv.ComputerName)
foreach ($row in $csv) {
  foreach ($col in 'OtherComputerName', 'OtherComputer', 'AndAgain') {
    if ($ref -contains $row.$col) { $row.$col = '' }
  }
}

$table = @()
$file = Get-Content .\test1.csv
$file = $file -replace("    "," ")
$file = $file -replace("   "," ")
$file = $file -replace("  "," ")
$file = $file -replace(" - "," ")

[string[]]$a = Import-Csv '.\test1.csv' | select -Expand ComputerName
[string[]]$b = Import-Csv '.\test1.csv' | select -Expand OtherComputerName
[string[]]$c = Import-Csv '.\test1.csv' | select -Expand OtherComputer
[string[]]$d = Import-Csv '.\test1.csv' | select -Expand AndAgain

$b | ? {$a -notcontains $_}
$c | ? {$a -notcontains $_}
$d | ? {$a -notcontains $_}

foreach ($line in $file) {
    $lineb = $line -split(" ")

    $obj = New-Object PSObject
    $obj | Add-Member -Name "ComputerName" -MemberType NoteProperty -Value $lineb[1]
    $obj | Add-Member -Name "OtherComputerName" -MemberType NoteProperty -Value $lineb[1]
    $obj | Add-Member -Name "OtherComputer" -MemberType NoteProperty -Value $lineb[2]
    $obj | Add-Member -Name "AndAgain" -MemberType NoteProperty -Value $lineb[3]

    $table += $obj
}

$table | ft -AutoSize

您需要将第一列的值读入数组，将其他列的值与该数组进行比较，并清除匹配字段：

$csv = Import-Csv .\test1.csv -Delimiter ';'

$ref = @($csv | Select-Object -Expand ComputerName)
foreach ($row in $csv) {
  foreach ($col in 'OtherComputerName', 'OtherComputer', 'AndAgain') {
    if ($ref -contains $row.$col) { $row.$col = '' }
  }
}

使用PowerShell显示Excel列的差异
