PowerShell 中 Format-Table cmdlet 的最大列数是多少 [英] What's the maximum number of columns for Format-Table cmdlet in PowerShell
本文介绍了PowerShell 中 Format-Table cmdlet 的最大列数是多少的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用 Format-Table，并且不能显示超过 9 个(无论是否带有 -AutoSize 参数).
以防万一这不是我的错，只是一些未记录的事情:
如果它是未绑定的，我会从我的脚本中提取一个小的可重现的案例.
我正在使用 PowerShell 4.0，并创建要列出的对象，如下所示:
New-Object PSCustomObject -Property ([Ordered] @{"BDS #" = $bdsVersion"HKCU" = $hkcuBasePathHKLM" = $hklmBasePath姓名"= $fullName"编译器版本" = $compilerVersion"RTLVersion" = $rtlVersion定义"= $define"字符集" = $characterSet架构"= $架构框架" = $frameworkDllSuffix" = $dllSuffix})即使我的控制台窗口足够宽(300 个字符宽)，DllSuffix 列也不会显示.
编辑:
根据 Cole9350 的 comment37399115_24218482">建议，我添加了 -Wrap 到 -AutoSize 参数 格式化表格，但它仍然失败:
function Get-BDS-ProductSummaries {$bdsVersions = Get-BDS-Versions$bdsVersions |ForEach-Object {$summary = Get-BDS-ProductSummary $_$summary} |Format-Table -AutoSize -Wrap# http://blogs.technet.com/b/nexthop/archive/2011/03/21/psformatorselect.aspx写主机斜线分隔值，如 xxx/yyy 表示本机/.NET"}我从脚本的主要"部分调用这个函数:
$args |ForEach-Object {$arg = $_开关($arg){# ...'产品摘要'{编写主持人产品摘要:"Get-BDS-ProductSummaries}# ...}$anyArg = $True}关于将 -Wrap 与 -Format-Table 结合使用的解释链接也表明有时并非所有列都会显示，但不会说明在什么情况下.
所以我正在寻找指导:什么时候它没有显示所有内容?
我什至对一些字段重新排序，并将 HKCU/HKLM 路径合并为一个字段并将其放在最后:
New-Object PSCustomObject -Property ([Ordered] @{"BDS #" = $bdsVersion姓名"= $fullName"编译器版本" = $compilerVersion"RTLVersion" = $rtlVersion定义"= $define"字符集" = $characterSet架构"= $架构框架" = $frameworkDllSuffix" = $dllSuffix项目版本"= $项目版本# "HKCU" = $hkcuBasePath# "HKLM" = $hklmBasePathHKCU/HKLM 注册表路径"= $basePath})它显示了一个 165 个字符宽的表格(而我的控制台窗口是 300 个字符宽):

默认情况下，Format-Table 只会显示 10 列.要获得它们，请使用*".有关详细信息，请参阅下面的示例和输出.
(仅供参考:-Wrap 在列显示但其中的数据被截断时使用.)

Just in case it is not my fault, just something undocumented:
What's the maximum number of columns which Format-Table can show?
If it is unbound, I'll distill a small reproducible case from my script.
I'm using PowerShell 4.0, and create the objects to list like this:
New-Object PSCustomObject -Property ([Ordered] @{
"BDS #" = $bdsVersion
"HKCU" = $hkcuBasePath
"HKLM" = $hklmBasePath
"Name" = $fullName
"CompilerVersion" = $compilerVersion
"RTLVersion" = $rtlVersion
"Define" = $define
"Characterset" = $characterSet
"Architectures" = $architecture
"Frameworks" = $framework
"DllSuffix" = $dllSuffix
})
The DllSuffix column doesn't show even though my console window is wide enough (300 characters wide).
Edit:
As per suggestion by Cole9350, I added the -Wrap to the -AutoSize argument to format the table, but it still fails:
function Get-BDS-ProductSummaries {
$bdsVersions = Get-BDS-Versions
$bdsVersions | ForEach-Object {
$summary = Get-BDS-ProductSummary $_
$summary
} | Format-Table -AutoSize -Wrap
# http://blogs.technet.com/b/nexthop/archive/2011/03/21/psformatorselect.aspx
Write-Host "Slash separated values like xxx/yyy means native/.NET"
}
I call this function from my "main" portion of the script:
$args | ForEach-Object {
$arg = $_
switch ($arg) {
# ...
'ProductSummaries' {
Write-Host "Product Summaries:"
Get-BDS-ProductSummaries
}
# ...
}
$anyArg = $True
}
The link explaining about combining -Wrap with -Format-Table also indicates that sometimes not all columns will show, but doesn't tell under what circumstances.
So I'm looking for guidance: when doesn't it show them all?
I even reordered some of the fields, and merged the HKCU/HKLM path into one field and put that last:
New-Object PSCustomObject -Property ([Ordered] @{
"BDS #" = $bdsVersion
"Name" = $fullName
"CompilerVersion" = $compilerVersion
"RTLVersion" = $rtlVersion
"Define" = $define
"Characterset" = $characterSet
"Architectures" = $architecture
"Frameworks" = $framework
"DllSuffix" = $dllSuffix
"ProjectVersion" = $projectVersion
# "HKCU" = $hkcuBasePath
# "HKLM" = $hklmBasePath
"HKCU/HKLM registry path" = $basePath
})
It shows a 165 character wide table (whereas my console Window is 300 characters wide):

With the path more towards the beginning, the output it 181 characters wide:
BDS # HKCU/HKLM registry path Name CompilerVersion RTLVersion Define Characterset Architectures Frameworks DllSuffix
----- ----------------------- ---- --------------- ---------- ------ ------------ ------------- ---------- ---------
With -Wrap, but without -AutoSize the last column doesn't show either.
When leaving the Format-Table away, it does show all fields, so New-Object PSCustomObject -Property does produce all properties:
BDS # : 14
HKCU/HKLM registry path : \Software\Embarcadero\BDS\14.0
Name : Embarcadero Delphi XE6
CompilerVersion : 27.0
RTLVersion : 27.0
Define : VER270
Characterset : Unicode
Architectures : Win32;Win64;OSX32;iOS-Arm;Android-Arm
Frameworks : VCL;FMX2
DllSuffix : 200
ProjectVersion : 15.4
解决方案
By default, Format-Table will only show 10 columns. To get them all, use "*". See Example and Output below for details.
(FYI: -Wrap is used when the column is being displayed but the data in it is being truncated.)
EXAMPLE:
$aryTemp = @()
$objTemp = New-Object PSObject
$objTemp | Add-Member -type NoteProperty -Name Column1 -Value "Data1"
$objTemp | Add-Member -type NoteProperty -Name Column2 -Value "Data2"
$objTemp | Add-Member -type NoteProperty -Name Column3 -Value "Data3"
$objTemp | Add-Member -type NoteProperty -Name Column4 -Value "Data4"
$objTemp | Add-Member -type NoteProperty -Name Column5 -Value "Data5"
$objTemp | Add-Member -type NoteProperty -Name Column6 -Value "Data6"
$objTemp | Add-Member -type NoteProperty -Name Column7 -Value "Data7"
$objTemp | Add-Member -type NoteProperty -Name Column8 -Value "Data8"
$objTemp | Add-Member -type NoteProperty -Name Column9 -Value "Data9"
$objTemp | Add-Member -type NoteProperty -Name Column10 -Value "Data10"
$objTemp | Add-Member -type NoteProperty -Name Column11 -Value "Data11"
$objTemp | Add-Member -type NoteProperty -Name Column12 -Value "Data12"
$objTemp | Add-Member -type NoteProperty -Name Column13 -Value "Data13"
$objTemp | Add-Member -type NoteProperty -Name Column14 -Value "Data14"
$objTemp | Add-Member -type NoteProperty -Name Column15 -Value "Data15"
$aryTemp += $objTemp
#only shows 10 columns
$aryTemp | Format-Table
#show all
$aryTemp | Format-Table *
OUTPUT:
Column1 Column2 Column3 Column4 Column5 Column6 Column7 Column8 Column9 Column10
------- ------- ------- ------- ------- ------- ------- ------- ------- --------
Data1 Data2 Data3 Data4 Data5 Data6 Data7 Data8 Data9 Data10
Column1 Column2 Column3 Column4 Column5 Column6 Column7 Column8 Column9 Column10 Column11 Column12 Column13 Column14 Column15
------- ------- ------- ------- ------- ------- ------- ------- ------- -------- -------- -------- -------- -------- --------
Data1 Data2 Data3 Data4 Data5 Data6 Data7 Data8 Data9 Data10 Data11 Data12 Data13 Data14 Data15
