iText 不添加一行表格

Question

我正在创建一个包含多个表格的 PDF 文档，当表格只有一行时，它不会将其添加到文档中。正如我在另一篇文章中看到的那样，我检查了该行是否已完成，并添加了table.completeRow() 以防万一。然而，唯一可行的方法是添加另一个空行：

table.addCell(new Paragraph("", paragraphFontNormal));
table.completeRow()

我认为这不是一个好的解决方案，我想知道这里出了什么问题。有人可以帮忙吗？

这是方法：

public void createPdf(DateRange dates, HttpServletResponse response) throws DocumentException, IOException {

    boolean first = true;
    Document document = new Document(PageSize.A4.rotate());
    PdfWriter.getInstance(document, response.getOutputStream());
    document.open();

    List<Rejects> report = findAll(dates);

    for(Rejects rejects : report){
        if (first) {
            first = false;
            addGroupAdmin(rejects, document, dates);
        }else{
            if (rejects.getAdminGroup().equals(adminGroup)) {
                table.addCell(new Paragraph(rejects.getZone(), paragraphFontNormal));
                table.addCell(new Paragraph(dateFormat.format(rejects.getRejDate()), paragraphFontNormal));
                table.addCell(new Paragraph(rejects.getProcName(), paragraphFontNormal));
                table.addCell(new Paragraph(rejects.getKindId(), paragraphFontNormal));
                table.addCell(new Paragraph(rejects.getVarietyName(), paragraphFontNormal));
                table.addCell(new Paragraph(rejects.getSlrn(), paragraphFontNormal));
                table.addCell(new Paragraph(rejects.getRejReason(), paragraphFontNormal));
                table.addCell(new Paragraph(rejects.getAdminGroup(), paragraphFontNormal));
                table.addCell(new Paragraph(rejects.getDescription(), paragraphFontNormal));
            }else{

                /*** It doesn't work like this for one row***/  
                document.add(table);

                document.newPage();
                addGroupAdmin(rejects, document, dates);
            }
        }
    }

    /*** It works like this ***/
    table.addCell(new Paragraph("", paragraphFontNormal));
    table.completeRow();
    document.add(table);

    document.newPage();
    response.flushBuffer();
    document.close();
}

这是 addGroupAdmin 方法：

private void addGroupAdmin(Rejects rejects, Document document, DateRange dates) throws DocumentException {
        adminGroup = rejects.getAdminGroup();
        Paragraph headLine = new Paragraph("REJECTED APPLICATION LIST " + dateFormat.format(dates.getStartDate())
                + "-" + dateFormat.format(dates.getEndDate()) + " - " + rejects.getAdminGroupDesc() , paragraphFontBold);
        headLine.setAlignment(Element.ALIGN_CENTER);
        document.add(headLine);
        document.add( Chunk.NEWLINE );

        table = new PdfPTable(9);
        table.getDefaultCell().setBorder(Rectangle.NO_BORDER);
        table.getDefaultCell().setMinimumHeight(20);
        table.getDefaultCell().setPaddingBottom(10);
        table.setWidthPercentage(900);
        table.setHeaderRows(1);
        table.setTotalWidth(new float[]{ 40, 60, 140, 30, 60, 90, 30, 90, 100 });
        table.setLockedWidth(true);

        table.addCell(new Paragraph(rejects.getZone(), paragraphFontNormal));
        table.addCell(new Paragraph(dateFormat.format(rejects.getRejDate()), paragraphFontNormal));
        table.addCell(new Paragraph(rejects.getProcName(), paragraphFontNormal));
        table.addCell(new Paragraph(rejects.getKindId(), paragraphFontNormal));
        table.addCell(new Paragraph(rejects.getVarietyName(), paragraphFontNormal));
        table.addCell(new Paragraph(rejects.getSlrn(), paragraphFontNormal));
        table.addCell(new Paragraph(rejects.getRejReason(), paragraphFontNormal));
        table.addCell(new Paragraph(rejects.getAdminGroup(), paragraphFontNormal));
        table.addCell(new Paragraph(rejects.getDescription(), paragraphFontNormal));
}

Answer 1

你设置

table.setHeaderRows(1);

这意味着您添加到表格的第一行用作标题行。

因此，如果

表格只有一行

那么表格有一个标题行但没有内容行。 iText 会忽略没有内容行的表格。因此，

它不会将它添加到文档中。

所以解决方案是不要在addGroupAdmin 方法中设置HeaderRows！
