C#: Insert Table after text in page

Hello. Can you help me. I want put my Aspose.Pdf.Table after all text in current page at existing pdf document. I can find only method Page.Paragraphs.Add(table). But in this, or in some other document, Page.Paragraphs.Count is 0. And when I put my table in page, table is placed at the top of the existing text.
Can I insert table after text in page?

@Bayer495

Thanks for contacting support.

We have already logged an issue as PDFNET-41545 in our issue tracking system, in order to add HtmlFragment after last paragraph inside a PDF document. As per my understandings, you also want to determine last paragraph of the PDF and add table right after it ends, so I have linked your post with the issue ID.

Furthermore, you may add a new page inside PDF by calling Document.Pages.Add() method and add table into newly added page. Concerning to the logged issue, as soon as the issue is resolved, we will definitely inform you within this forum thread. Please be patient and spare us little time.

We are sorry for the inconvenience.

I have similar problem. My solution is to add (empty) Graph object before adding the table.
I calculate width and height of Graph object I use the data from TextFragmentAbsorber fragments.
Here is my console app for testing (see AddInvoiceData method):

using System;
using System.Data;
using System.IO;
using System.Linq;
using Aspose.Pdf;
using Aspose.Pdf.Text;
using TextState = Aspose.Pdf.Text.TextState;
namespace ExampleConsole
{
    class Program

        private const string AsposeTemplatePdf = @"c:\aspose\template.pdf";
        private const string AsposeDocumentPdf = @"c:\aspose\document.pdf";
        private static DataTable _productsDataTable;
        private static readonly Aspose.Pdf.License license = new Aspose.Pdf.License();
        static void Main()
        {
            // Set license
            license.SetLicense(@"C:\\Keys\\Aspose.Pdf.lic");
            _productsDataTable = GenerateDataTable();
            AddInvoiceData();
        }    
        private static DataTable GenerateDataTable()
        {
            var dt = new DataTable("InovoiceItems");
            dt.Columns.Add("ID", typeof(int));
            dt.Columns.Add("ItemName", typeof(string));
            dt.Columns.Add("Price", typeof(float));
            dt.Columns.Add("Qunatity", typeof(int));
            dt.Columns.Add("Summa", typeof(float));

            // Add 5 rows into the DataTable object programmatically
            var dr = dt.NewRow();
            for (var i = 0; i < 5; i++)
            {
                dr[0] = i + 1;
                dr[1] = $"Sun Glasses Type {i + 1}";
                dr[2] = 199.99;
                dr[3] = 1;
                dr[4] = 199.99;
                dt.Rows.Add(dr);
                dr = dt.NewRow();
            }
            return dt;

Wow! It’s a wonderful solution! Thank you.

The issues you have found earlier (filed as PDFNET-41545) have been fixed in Aspose.PDF for .NET 22.2.
