使用powershell将文本列添加到csv的开头

Question

我正在使用下面的脚本将电子表格转换为csv格式。我需要做的是在开头添加一个标有“订单类型代码”的列，其下的每个条目都会简单地说“SO”

#CBRCust,StoreNum,StoreName,Load,Stop,Item,Quantity,Pack,Size,ItemDescription,UPC

$headers = "CBRCust","StoreNum","StoreName","Load","Stop","Item","Quantity","Pack","Size","ItemDescription","UPC"
$source = Import-Csv Sample.csv -Header $headers

#setup Output Table
$tabName = "Output"

#Create Table object
$table = New-Object system.Data.DataTable “$tabName”

#Define Columns
$col1 = New-Object system.Data.DataColumn ColumnName1,([string])
$col2 = New-Object system.Data.DataColumn ColumnName2,([string])

#Add the Columns
$table.columns.add($col1)
$table.columns.add($col2)

#Index the source and create a new table.foreach ($row in $source)
{
    $newrow = $table.NewRow()
    $newrow.ColumnName1 = $row."CBRCust"
    $newrow.ColumnName2 = $row."StoreName"
   $table.Rows.Add($newrow)
}

    #output Table
$table | format-table -AutoSize 
#save file
$table | Export-Csv Output.csv -NoTypeInformation

我尝试使用下面的脚本，但它没有用

#Define Columns
$col1 = New-Object system.Data.DataColumn OrderTypeCode,([string])
$col2 = New-Object system.Data.DataColumn ColumnTest1,([string])
$col3 = New-Object system.Data.DataColumn ColumnName2,([string])


#Add the Columns
$table.columns.add($col1)
$table.columns.add($col2)

#Index the source and create a new table.
foreach ($row in $source)
{
    $newrow = $table.NewRow()
    $newrow.OrderTypeCode = 'SO' 
    $newrow.ColumnTest1 = $row."CBRCust"
    $newrow.ColumnName2 = $row."StoreName"
    $table.Rows.Add($newrow)
}

Answer 1

好吧，如果你不需要DataTable，看看它是否能满足你的需求：

$headers = "CBRCust","StoreNum","StoreName","Load","Stop","Item","Quantity","Pack","Size","ItemDescription","UPC"
$source = Import-Csv Sample.csv -Header $headers
$source | Select CBRCust, StoreName, @{n='OrderTypeCode'; e={'SO'}} | Export-CSV Output.csv -NoTypeInformation

Answer 2

所以我想出了怎么做。只需将列定义为文本字段而不是数据列

#CBRCust,StoreNum,StoreName,Load,Stop,Item,Quantity,Pack,Size,ItemDescription,UPC

$headers = "CBRCust","StoreNum","StoreName","Load","Stop","Item","Quantity","Pack","Size","ItemDescription","UPC"
$source = Import-Csv Sample.csv -Header $headers

#setup Output Table
$tabName = "Output"

#Create Table object
$table = New-Object system.Data.DataTable “$tabName”

#Define Columns
$col1 = 'Order Type Code'
$col2 = New-Object system.Data.DataColumn OrderNo,([string])
$col3 = New-Object system.Data.DataColumn OrderNo2,([string])
$col4 = New-Object system.Data.DataColumn OrderNo3,([string])
$col5 = New-Object system.Data.DataColumn OrderNo4,([string])
$col6 = New-Object system.Data.DataColumn OrderNo5,([string])
$col7 = New-Object system.Data.DataColumn VendorCode,([string])
$col8 = New-Object system.Data.DataColumn AccountCode,([string])
$col9 = New-Object system.Data.DataColumn FromWarehouse,([string])
$col10 = New-Object system.Data.DataColumn ToWarehouse,([string])
$col11 = New-Object system.Data.DataColumn AddressOverride,([string])
$col12 = New-Object system.Data.DataColumn AddressLine1,([string])
$col13 = New-Object system.Data.DataColumn AddressLine2,([string])
$col14 = New-Object system.Data.DataColumn City,([string])
$col15 = New-Object system.Data.DataColumn State,([string])
$col16 = New-Object system.Data.DataColumn Zip,([string])
$col17 = New-Object system.Data.DataColumn Country,([string])
$col18 = New-Object system.Data.DataColumn ContactName,([string])
$col19 = New-Object system.Data.DataColumn ContactPhone,([string])
$col20 = New-Object system.Data.DataColumn ContactExt,([string])
$col21 = New-Object system.Data.DataColumn ContactFax,([string])
$col22 = New-Object system.Data.DataColumn OwnerCode,([string])
$col23 = New-Object system.Data.DataColumn CarrierCode,([string])
$col24 = New-Object system.Data.DataColumn LeavesDate,([string])
$col25 = New-Object system.Data.DataColumn ArrivesDate,([string])
$col26 = New-Object system.Data.DataColumn DeliveryInstructions,([string])
$col27 = New-Object system.Data.DataColumn Stop,([string])


#Add the Columns
$table.columns.add($col1)
$table.columns.add($col2)
