表插入空白单元格

Posted 2021-04-17

我正在尝试将列表导入html格式的表。它似乎正在按预期工作，除了我有很多单元格填充空白。我试图使用修剪和其他方法删除所有额外的空格，但额外的空格仍然在表中。

这是代码。

uemcli -d 192.168.1.100 -u Local/admin -p admin /event/alert/hist show -acknowledged no |
    select -Skip 4 > $PSSCriptRootoutput.txt

$nl = [System.Environment]::NewLine
$unity = Get-Content $PSScriptRootoutput.txt

$unity = $unity -replace "[0-9]:",""
$unity = $unity -replace "=",":"
$unity = $unity -replace "$n1$n1",""
$unity = $unity.Trim()

$UnitySummary = ($unity) -split '$n1$n1' | foreach {
    $Stringdata = $_.Replace(':','=') -replace '$n1',''
    New-Object PSObject -Property $(ConvertFrom-StringData $Stringdata)
} 

$style = @"
<style>
TABLE{border-width: 1px;border-style: solid;border-color: black;border-collapse: collapse; }
TH{border-width: 2px;padding: 3px;border-style: solid; border-color: black;background-color: #08088A; color: white; font-size: 67%;}
TD{border-width: 2px;padding: 3px;border-style: solid; border-color: black; font-size: 100%;}
</style>
"@

$unitySummary |
    select 'Id','Time','Message' |
    ConvertTo-Html -Head $style |
    Out-File $PSScriptRootweboutput.html

这是我在第一行（output.txt）处理的原始文件：

这是我得到的输出。您可以看到项目放在正确的列中，但是插入了额外的空白单元格，导致数据显示在错误的行中。

答案

Get-Content不会将输入文件读作单个字符串，而是读取行数组。因为New-Object只创建具有单个属性的对象。通过select 'Id','Time','Message'管道结果然后添加其他属性，仅使用空值。

通过Get-Content管理Out-String的输出来解决这个问题：

$unity = Get-Content $PSScriptRootoutput.txt | Out-String

在PowerShell v3和更新版本上，您也可以使用参数Get-Content调用-Raw以获得相同的结果：

$unity = Get-Content $PSScriptRootoutput.txt -Raw

另一答案

请接受Ansgar的回答，因为它解决了您的问题的根源。我发布这个作为额外的帮助，让你得到你想要的东西。

而不是将整个事物作为一个字符串读取，将其拆分，进行多次替换（包括将所有等号转换为冒号，然后将所有冒号转换为等号），取大字符串，将其拆分为条目（由数字后跟一行开头的冒号），并通过ConvertFrom-StringData管道每个条目并从中创建对象。它将为您提供我非常确定您希望能够传递到您的表中的内容（选择您想要的粗略属性）。

您甚至可以通过将原始命令传送到Out-String来跳过整个保存到磁盘并将其读回。

$Unity = uemcli -d 192.168.1.100 -u Local/admin -p admin /event/alert/hist show -acknowledged no |
    select -Skip 4 |
    Out-String
$Unity -split '(?m)^d:' |
    Where{$_.Trim()} |
    ForEach{ [PSCustomObject](ConvertFrom-StringData -StringData $_) }

然后你只需将它输出到你的ConvertTo-Html就可以了。

$Unity = uemcli -d 192.168.1.100 -u Local/admin -p admin /event/alert/hist show -acknowledged no |
        select -Skip 4 |
        Out-String
