    This is my code to add data from datatable to richtextbox on table format
 dt = new DataTable();
                        SQLiteConnection conn = new SQLiteConnection("Data Source=" + folderPath + "\\" + databaseName);
                        InitializeComponent();
                        s = MyProperty.ToString();
                        conn.Open();
                        SQLiteCommand command = new SQLiteCommand("SELECT id,nameSearch,dt,totalRecords FROM ACCESSDETAILS Where id=" + s + " AND numberSearch IS NULL AND dt BETWEEN '" + datepicker + "' AND '" +  datepicker1+ "'", conn);
                        SQLiteDataAdapter da = new SQLiteDataAdapter(command);
                        da.Fill(dt);                        
                        conn.Close() 
var tab = new Table();
