使用iTExtsharp将表添加到现有PDF中

Question

我有一个PDF,因为有一个表是动态的表,我想在我现有的PDF中动态地在下面添加另一个表.

有没有办法在现有PDF中添加现有表格(不在文档末尾)的特定位置,然后我想添加我的表格.

我该如何添加？请建议我一些好方法.

如下图所示.

谢谢,

using iTextSharp.text;
using iTextSharp.text.pdf;

/// Function which will create pdf document and save in the server folder

private void ExportDataToPDFTable()
    {
      Document doc = new Document(iTextSharp.text.PageSize.LETTER, 10, 10, 42, 35);
         try
          {
           string pdfFilePath = Server.MapPath(".") + "/pdf/myPdf.pdf";
           //Create Document class object and set its size to letter and give space left, right, Top, Bottom Margin
           PdfWriter wri = PdfWriter.GetInstance(doc, new FileStream(pdfFilePath, FileMode.Create));

           doc.Open();//Open Document to write

           Font font8 = FontFactory.GetFont("ARIAL", 7);

           //Write some content
            Paragraph paragraph = new Paragraph("Using ITextsharp I am going to show how to create simple table in PDF document ");

            DataTable dt = GetDataTable();

            if (dt != null)
                {
                 //Craete instance of the pdf table and set the number of column in that table
                 PdfPTable PdfTable = new PdfPTable(dt.Columns.Count);
                 PdfPCell PdfPCell = null;


                 //Add Header of the pdf table
                 PdfPCell = new PdfPCell(new Phrase(new Chunk("ID", font8)));
                 PdfTable.AddCell(PdfPCell);

                 PdfPCell = new PdfPCell(new Phrase(new Chunk("Name", font8)));
                 PdfTable.AddCell(PdfPCell);


                 //How add the data from datatable to pdf table
                 for (int rows = 0; rows < dt.Rows.Count; rows++)
                    {
                     for (int column = 0; column < dt.Columns.Count; column++)
                         {
                           PdfPCell = new PdfPCell(new Phrase(new Chunk(dt.Rows[rows][column].ToString(), font8)));
                            PdfTable.AddCell(PdfPCell);
                            }
                        }

                        PdfTable.SpacingBefore = 15f; // Give some space after the text or it may overlap the table

                        doc.Add(paragraph);// add paragraph to the document
                        doc.Add(PdfTable); // add pdf table to the document

                    }

                }
                catch (DocumentException docEx)
                {
                    //handle pdf document exception if any
                }
                catch (IOException ioEx)
                {
                    // handle IO exception
                }
                catch (Exception ex)
                {
                    // ahndle other exception if occurs
                }
                finally
                {
                    //Close document and writer
                    doc.Close();

       }
 }

样本数据表：

private DataTable GetDataTable()
    {
        // Create an object of DataTable class
        DataTable dataTable = new DataTable("MyDataTable");//Create ID DataColumn
        DataColumn dataColumn_ID = new DataColumn("ID", typeof(Int32));
        dataTable.Columns.Add(dataColumn_ID);//Create another DataColumn Name
        DataColumn dataColumn_Name = new DataColumn("Name", typeof(string));
        dataTable.Columns.Add(dataColumn_Name);
        //Now Add some row to newly created dataTable
        DataRow dataRow;for (int i = 0; i < 5; i++)
        {
            dataRow = dataTable.NewRow();
            // Important you have create New row
            dataRow["ID"] = i;dataRow["Name"] = "Some Text " + i.ToString();
            dataTable.Rows.Add(dataRow);
        }
        dataTable.AcceptChanges();
        return dataTable;
    }
