            myFlowDoc.Blocks.Add(T);
            T.CellSpacing = 1;
        
          
            for (int x = 0;x<5;x++) { T.Columns.Add(new TableColumn()); }
            T.Columns[0].Background = Brushes.Beige;
            T.Columns[0].Width = new GridLength(200);
            T.Columns[1].Width = new GridLength(150);

            T.BorderThickness = new Thickness(1);
            T.BorderBrush = Brushes.Red;
           

            T.RowGroups.Add(new TableRowGroup());
            T.RowGroups[0].Rows.Add(new TableRow());  // ajout titre

            currentRow.Background = Brushes.Silver;    /// ok
