[表-PDFbox中的值将被覆盖

Question

我想以行和列显示记录集。正在获取输出，但事实是，它正在重叠。我应该修改循环吗，有人可以建议。

 ArrayList<ResultRecord> Records = new ArrayList<ResultRecord>(MainRestClient.fetchResultRecords(this.savedMainLog));
 for(j=0; j<Records.size(); j++)
           {
                Row<PDPage> row4 = table.createRow(100.0f);
                Cell<PDPage> cell10 = row4.createCell(15.0f, temp.getNumber());
                Cell<PDPage> cell11 = row4.createCell(45.0f, temp.getDescription());
                Cell<PDPage> cell12 = row4.createCell(15.0f, temp.getStatus());
                Cell<PDPage> cell13 = row4.createCell(25.0f, temp.getRemarks());
                }

下面是打开PDF文件的完整代码。我想检索相应单元格中row4中的记录集。但是，一个被覆盖在另一个之上。预期产量：IT应该在另一个下方显示。是重叠的原因，是因为将行定义为row4。

System.out.println("----------------------Report starts-------------------------------------------");


System.out.println(MainRestClient.fetchResultRecords(this.savedMainLog));

        ArrayList<ResultRecord> Records = new ArrayList<ResultRecord>(MainRestClient.fetchResultRecords(this.savedMainLog));
        System.out.println(Records.size());

        //Creating PDF document object
        PDDocument document = new PDDocument();
        PDPage page = new PDPage(PDRectangle.A4);
        // PDRectangle.LETTER and others are also possible
        PDRectangle rect = page.getMediaBox();

        document.addPage(page);
        boolean drawContent = true;
        float margin = 50;
        // starting y position is whole page height subtracted by top and bottom margin
        float yStartNewPage = page.getMediaBox().getHeight() - (2 * margin);
        // we want table across whole page width (subtracted by left and right margin ofcourse)
        float tableWidth = page.getMediaBox().getWidth() - (2 * margin);
        float bottomMargin = 70;
        // y position is your coordinate of top left corner of the table
        float yPosition = 550;

        System.out.println("PDF created");

        for(int i=0;i<Records.size();i++) {

            System.out.println(Records.get(i));
            ResultRecord temp = (ResultRecord) Records.get(i);

            Row<PDPage> row = table.createRow(20.0f);
            Cell<PDPage> cell = row.createCell(50.0f, "Checklist Number:" + temp.getChecklistId());
            Cell<PDPage> cell1 = row.createCell(50.0f, "CDSID:" + temp.getCDSID());

                }

            try {
                table.draw();
                cell.setFontSize(12);
            } catch (Exception e) {
                System.out.println(e.getMessage());
            }
        }

        try {
            document.save("C:\\my_doc.pdf");
            document.close();
        } catch (IOException e) {
            System.out.println(e.getMessage());
        }


    }`

首先，您应该弄清所使用的表格图形库。 PDFBox仅是基础PDF库。考虑使用的类，我假设您在其顶部使用Boxable。

此外，所有表格彼此打印的原因是，您使用同一页上相同位置的每个表格来启动]

BaseTable table = new BaseTable(yPosition, yStartNewPage,
        bottomMargin, tableWidth, margin, document, page, true, drawContent);
