TableRow tr = new TableRow();



for (int j = 1; j <= 3; j++)



{



TableCell td = new TableCell();



TextBox c_text = new TextBox();



c_text.Visible = true; 



c_text.Text = "R"+i.ToString()+j.ToString();



c_text.ID = "R" + i.ToString() + j.ToString();



td.Controls.Add(c_text);



tr.Cells.Add(td);



tb.Rows.Add(tr);
