My solution:

Simple solution is create Table object and add to blocks of richtextbox, somothing like this:

        var tab = new Table();

        var gridLenghtConvertor = new GridLengthConverter();

        tab.Columns.Add(new TableColumn() { Name = "colNick", Width = (GridLength)gridLenghtConvertor.ConvertFromString("*") });
        tab.Columns.Add(new TableColumn { Name = "colMsg", Width = (GridLength)gridLenghtConvertor.ConvertFromString("5*") });
        tab.Columns.Add(new TableColumn() { Name = "colDt", Width = (GridLength)gridLenghtConvertor.ConvertFromString("*") });

        tab.RowGroups.Add(new TableRowGroup());
        tab.RowGroups[0].Rows.Add(new TableRow());

        var tabRow = tab.RowGroups[0].Rows[0];


        tabRow.Cells.Add(new TableCell(new Paragraph(new Run(rpMsg.Nick))) { TextAlignment = TextAlignment.Left });

        tabRow.Cells.Add(new TableCell(ConvertToRpWithEmoticons(rpMsg.RpText)));

        tabRow.Cells.Add(new TableCell(new Paragraph(new Run("Cas"))) { TextAlignment = TextAlignment.Right });

        RtbConversation.Document.Blocks.Add(tab);
