C# Excel VSTO - add a table to a range

im very new to c# and i was hoping that you can help me a bit out.
Currently i'm working on an Excel-VSTO Addin which read a sqlite3-databasefile.
The results of the queries are stored in arrays.
I write these arrays to specified Excel cells.

So far so good - now i want to create a listObject out of this range. Im stuck with my method:

private void build_table4(string StartCol, int StartRow, string EndCol, int RowsCount, int ColCount, Boolean show_totals, string TableStyle, string TableName, int IncludeRowsBefore)

    {



        string StartCell = StartCol + Convert.ToString(StartRow - IncludeRowsBefore);

        string EndCell = EndCol + Convert.ToString(StartRow + RowsCount);



        Microsoft.Office.Interop.Excel.Workbook xlWb = Globals.ThisAddIn.Application.ActiveWorkbook;

        Microsoft.Office.Interop.Excel.Worksheet xlWorksheet = xlWb.Sheets[1];



        //Excel.Range tableRange = (Excel.Range)xlWorksheet.Range[xlWorksheet.Cells[StartCellY, StartCellX], xlWorksheet.Cells[ToCellY, ToCellX]];

       Excel.Range tableRange = (Excel.Range)xlWorksheet.Range[StartCell, EndCell];



         Excel.ListObject list = xlWorksheet.ListObjects.Add(Excel.XlListObjectSourceType.xlSrcRange, tableRange,

                                                 Type.Missing, Excel.XlYesNoGuess.xlYes, Type.Missing);



        //list.Name = "Table";

        list.Name = TableName;

        //list.TableStyle = "TableStyleMedium2";

        list.TableStyle = TableStyle;

        //list.ShowTotals = show_totals;

        //xlWorksheet.Rows.AutoFit();

        //xlWorksheet.Columns.AutoFit();

        Excel.ListRow row = list.ListRows.AddEx(Type.Missing, Type.Missing);



        //MessageBox.Show("StartCellX:" + StartCellX + ", StartCellY:" + StartCellY + ", RowsCount:" + RowsCount + ", ColCount:" + ColCount + ", ToCellX:" + ToCellX + ", ToCellY:" + ToCellY);

    }

When i call it like this:

private void button1_Click(object sender, RibbonControlEventArgs e)

    {  

        build_table4("B", 3, "H", 15, 7, false, "", "Daten", 0);

    }

I tried out a lot but i havent found a solution yet.
It always adds two additional rows that i did not expect and i couldnt find out why:

Before and after

I hope you have some tips for me. Thanks in advance.
Sorry for my bad english :x

Ok, i found my mistakes: First i forgot to comment this line out: Excel.ListRow row = list.ListRows.AddEx(Type.Missing, Type.Missing); Second the following line has to change from this: string EndCell = EndCol + Convert.ToString(StartRow + RowsCount); to this: string EndCell = EndCol + Convert.ToString(StartRow + RowsCount - 1);
