改成

Dim tp As WinForm.TabControl = e.sender
Select Case tp.SelectedPage.Text
    Case "批量录入"

        If Tables("原材料").Rows.Count = 0 Then '如果是一个空表
            Return '那么返回
        End If
        Dim idxs As String = "-1,"
        Dim dr As Row = Tables("原材料").Current
        For Each dc As Col In Tables("原材料").Cols
            For i As Integer = 1 To 4
                Dim nr As Row = Tables("原材料进场录入_Table1").AddNew
                idxs & = nr("_Identify") & ","
                nr(dc.name) = dr(dc.Name)
            Next
        Next
        Tables("原材料进场录入_Table1").filter = "_Identify in (" & idxs.Trim(",") & ")"
End Select

这个意思

Dim tp As WinForm.TabControl = e.sender
Select Case tp.SelectedPage.Text
    Case "批量录入"
        If Tables("原材料").Rows.Count = 0 Then '如果是一个空表
            Return '那么返回
        End If
        Dim idxs As String = "-1,"
        Dim dr As DataRow = Tables("原材料").Current.DataRow
        If dr.RowState = DataRowState.Unchanged Then
            For i As Integer = 1 To 4
                Dim nr As Row = Tables("原材料进场录入_Table1").AddNew
                idxs & = nr("_Identify") & ","
                For Each dc As Col In Tables("原材料").Cols
                    nr(dc.name) = dr(dc.Name)
                Next
            Next
            Tables("原材料进场录入_Table1").filter = "_Identify in (" & idxs.Trim(",") & ")"
        End If
End Select
