How to copy cells from one Table to another in .NET?

By Marat Mirgaleev

Q: Is there any way to copy the contents of several rows/cells to another Table?

A: Yes. You need to use the Table.CopyFrom method and pass two CellRange objects to it.
The following command copies two rows from a selected table to a new table.

// Copy some cells from a table to a new one.    //=================================================================    [CommandMethod("_copyCells")]    public static void copyCells()    {      Document doc = Application.DocumentManager.MdiActiveDocument;      Editor ed = doc.Editor;           PromptEntityOptions opts =                         new PromptEntityOptions("nSelect a Table: ");      opts.SetRejectMessage("This is not a Table.");      opts.AddAllowedClass(typeof(Table), false);      opts.AllowNone = false;      PromptEntityResult res = ed.GetEntity(opts);           if (res.Status != PromptStatus.OK)        return;           PromptPointResult pr =                 doc.Editor.GetPoint("nEnter table insertion point: ");      if (pr.Status != PromptStatus.OK)        return;           using (Transaction tr =doc.TransactionManager.StartTransaction())      {        BlockTable bt = tr.GetObject(doc.Database.BlockTableId,                                         OpenMode.ForRead) as BlockTable;        BlockTableRecord ms = tr.GetObject(                                bt[BlockTableRecord.ModelSpace],                                OpenMode.ForWrite) as BlockTableRecord;        Table sourceTb = tr.GetObject(res.ObjectId,                                     &#
160;       OpenMode.ForRead) as Table;             // Create a new Table        Table newTb = new Table();        newTb.TableStyle = doc.Database.Tablestyle;        newTb.SetSize(8, 5); /* In previous versions of AutoCAD                               * we did it like this:                                  newTb.NumRows = 8;                                  newTb.NumColumns = 5; */        newTb.Position = pr.Value;             // Copy two last rows from the selected table to the new one        newTb.CopyFrom(sourceTb, TableCopyOptions.FillTarget,            CellRange.Create(sourceTb, sourceTb.Rows.Count-2, 0,                      sourceTb.Rows.Count-1, sourceTb.Columns.Count-1),            CellRange.Create(newTb, 3, 0, 4, sourceTb.Columns.Count-1));        newTb.GenerateLayout();             newTb.Cells[1, 1].Style = newTb.Cells[1, 1].Style;             ms.AppendEntity(newTb);        tr.AddNewlyCreatedDBObject(newTb, true);             tr.Commit();      }    } // End of copyCells()
