使用 ListObject.Add 创建 Table 样式时出错

Question

我正在尝试使用 PowerShell 和 Excel ComObject 从 CSV

这是我的代码...

$Excel = New-Object -ComObject excel.application 
$Excel.visible = $true
$Excel.sheetsInNewWorkbook = $csvFiles.Count
$workbooks = $excel.Workbooks.Add()
$worksheets = $workbooks.worksheets
$CSVFullPath = C:\temp.csv
$worksheet = $worksheets.Item(1)
$worksheet.Name = "Temp"

$TxtConnector = ("TEXT;" + $CSVFullPath)
$CellRef = $worksheet.Range("A1")

$Connector = $worksheet.QueryTables.add($TxtConnector,$CellRef)
$worksheet.QueryTables.item($Connector.name).TextFileCommaDelimiter = $True
$worksheet.QueryTables.item($Connector.name).TextFileParseType  = 1
$worksheet.QueryTables.item($Connector.name).Refresh()
$worksheet.UsedRange.EntireColumn.AutoFit()

## So Far So good - CSV Imported ##
## My Problem Starts here... ##

$listObject = $worksheet.ListObjects.Add([Microsoft.Office.Interop.Excel.XlListObjectSourceType]::xlSrcRange, $worksheet.UsedRange, $null),[Microsoft.Office.Interop.Excel.XlYesNoGuess]::xlYes,$null) 

## Then I Received the following error: ##

Exception calling "Add" with "5" argument(s): "A table cannot overlap a range that contains a PivotTable report, query
results, protected cells or another table."
At line:1 char:41
+ $ListObject = $WorkSheet.ListObjects.Add <<<< ([Microsoft.Office.Interop.Excel.XlListObjectSourceType]::xlSrcRange,$R
ange,$null,[Microsoft.Office.Interop.Excel.XlYesNoGuess]::xlYes,$null)
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : ComMethodTargetInvocation

我已经研究了一段时间，但没有找到解决方案。

根据您的代码，您不能将 ListObject 添加到 Worksheet，而基础 QueryTable 仍然存在。如果您尝试在正常 Excel（非 COM）中执行此操作，您将收到如下错误：

如果您点击 Yes 并在它工作时录制宏，Excel 只会删除 QueryTable 并添加 ListObject。删除 QueryTable 不会影响基础数据。

在 VBA 世界中，您的代码将如下所示：

Sub DeleteQueryTableAndAddListObject()

    Dim sht As Worksheet
    Set sht = ActiveSheet

    ''code up here to create a QueryTable

    Dim i As Integer
    For i = sht.QueryTables.Count To 1 Step -1
        sht.QueryTables(i).Delete
    Next i

    sht.ListObjects.Add xlSrcRange, sht.UsedRange, , xlYes

End Sub

尝试一下 PowerShell（不是我的母语）你应该能够做到：

$worksheet.QueryTables.item($Connector.name).Delete()

或者可能：

$Connector.Delete()

因为 $Connector 似乎是对 QueryTable 对象的有效引用。
