    [CommandMethod("testaddtable")]
public void testaddtable()
{
    Database  db =
        HostApplicationServices.WorkingDatabase;
 
    using (Transaction tr =
        db.TransactionManager.StartTransaction())
    {
        BlockTable bt =
            (BlockTable)tr.GetObject(db.BlockTableId,
                                    OpenMode.ForRead);
        ObjectId msId =
            bt[BlockTableRecord.ModelSpace];
        BlockTableRecord btr =
            (BlockTableRecord)tr.GetObject(msId,
                                OpenMode.ForWrite);
        // create a table
        Table tb = new Table();
        tb.TableStyle = db.Tablestyle;
        // row number
        Int32 RowsNum = 5;
        // column number
        Int32 ColumnsNum = 5;
        // row height
        double rowheight = 3;
        // column width
        double columnwidth = 20;

        // insert rows and columns
        tb.InsertRows(0, rowheight, RowsNum);
        tb.InsertColumns(0, columnwidth, ColumnsNum);
        tb.SetRowHeight(rowheight);
        tb.SetColumnWidth(columnwidth);

        Point3d eMax = db.Extmax;
        Point3d eMin = db.Extmin;
        double CenterY = (eMax.Y + eMin.Y) * 0.5;
        tb.Position = new Point3d(10, 10, 0);

        // fill in the cell one by one
        for (int i = 0; i < RowsNum; i++)
        {
            for (int j = 0; j < ColumnsNum; j++)
            {
                tb.Cells[i, j].TextHeight =  1;
                if (i == 0 && j == 0)
                    tb.Cells[i, j].TextString =
                        "The Title";
                else
                    tb.Cells[i, j].TextString =
                        i.ToString() + "," + j.ToString();
                tb.Cells[i,j].Alignment =
                    CellAlignment.MiddleCenter;
            }
        }

        tb.GenerateLayout();
        btr.AppendEntity(tb);
        tr.AddNewlyCreatedDBObject(tb, true);
        tr.Commit();
