tables[0].ToJson or ToCsv are not implemented error

[princeharish]

            ```
        var doc = PdfDocument.Open(@"W:\OCR\foo.pdf", new ParsingOptions() { ClipPaths = true });

            var page = doc.GetPage(1);

            Lattice lattice = new Lattice(new OpenCvImageProcesser(), new BasicSystemDrawingProcessor(), line_scale: 40);
            List<Camelot.Core.Table> tables = lattice.ExtractTables(page,
                layout_kwargs: new DlaOptions[]
                {
                    new DocstrumBoundingBoxes.DocstrumBoundingBoxesOptions()
                    {
                        WithinLineMultiplier = 2
                    }
                });
            DataTable dt = new DataTable();
            for (int i = 0; i < tables[0].Cells.Count; i++)
            {
                dt.Columns.Add(tables[0].Cells[i][0].Text);
            }
            tables[0].ToExcel("temp.xlsx");

This code thows  System.NotImplementedException: The method or operation is not implemented on table[0].ToExcel function call.
            
If I am doing wrong, is there any other ways to export the table?
