想要实现对多个sheet的含有某些特定字段的所在列进行隐藏，下边这段运行显示类型不匹配错误，请问各位大神是为什么？



Sub 隐藏或删除包含特定字段的列 ()   
   Dim ws As Worksheet   
   Dim targetColumns() As String   
   Dim rng As Range  
   Dim i As Integer

   ' 设置需要隐藏或删除的字段名   
   Dim data As Variant  
   data = Array("字段 1 名", "字段 2 名", "字段 3 名")  
   targetColumns = data

   ' 遍历工作表   
   For Each ws In ThisWorkbook.Worksheets   
       ' 设置需要隐藏列的 Range   
       Set rng = ws.Range(ws.Cells(1, 1), ws.Cells(ws.Rows.Count, 1).End(xlToLeft))   
           
       ' 检查该列是否包含特定字段   
       Dim cellValue As Variant  
       For i = LBound(targetColumns) To UBound(targetColumns)  
           cellValue = rng.Cells(1, 1).Value  
           If cellValue = targetColumns(i) Then  
               ' 隐藏该列   
               If i = LBound(targetColumns) Then  
                   rng.Hide Shift:=xlToLeft   
               End If  
           End If  
       Next i  
   Next ws   
End Sub   

Dim targetColumns() As String   改成
 Dim targetColumns()
