Question

我想使用itext创建一个pdf，在我的jsp文件中，我创建一个按钮，每当有人点击该按钮pdf必须下载时，大多数所有东西都在这里工作正常但我无法添加我的表内容，它在桌子的地方显示为空。我的段落已添加但在段落后我想添加一个不添加的小表。有人请帮我解决这些问题，这是我的代码：

/itext.jsp

public partial class MainPage : ContentPage 
    { 
        public MainPage() 
        { 
            InitializeComponent(); 
            btnHello.Clicked += BtnHello_Clicked; 
        } 
 
        private void BtnHello_Clicked(object sender, EventArgs e) 
        { 
            lblDetail.Text = entryHello.Text; 
        } 
    }

/itextcontroller.java

function downloadfForm()
{
    document.location.href = './downloadPDF';
}


 <div class="col-md-3 col-sm-3">
          <div class="form-group">
              <label class="no-bold hidden hidden-md hidden-lg">&nbsp;</label>
              <a href="javascript:void(0)" class="btn btn-warning mutual-funds-submit-anchor" onclick="downloadfForm()">downloadfForm</a>             
          </div>          
          </div>

尝试按照代码使用iText库创建一个pdf表.hope这将对您有所帮助。

        PdfPTable table1 = new PdfPTable(4);

        float[] columnWidths1 = new float[]{30f, 10f, 30f, 10f};
        table1.setWidths(columnWidths1);

        table1.setWidthPercentage(100);
        table1.setHorizontalAlignment(table.ALIGN_JUSTIFIED);
        PdfPCell c1 = new PdfPCell(new Phrase("Details", blackNormalFont));
        c1.setHorizontalAlignment(Element.ALIGN_CENTER);

        c1.setBackgroundColor(BaseColor.GRAY);
        table1.addCell(c1);

        c1 = new PdfPCell(new Phrase("Amount (Rs)", blackNormalFont));
        c1.setHorizontalAlignment(Element.ALIGN_CENTER);
        c1.setBackgroundColor(BaseColor.GRAY);
        c1.setHorizontalAlignment(Element.ALIGN_RIGHT);
        table1.addCell(c1);

        c1 = new PdfPCell(new Phrase("Deductions by HDBFS", blackNormalFont));
        c1.setHorizontalAlignment(Element.ALIGN_CENTER);
        c1.setBackgroundColor(BaseColor.GRAY);
        table1.addCell(c1);

        c1 = new PdfPCell(new Phrase("Amount (Rs)", blackNormalFont));
        c1.setHorizontalAlignment(Element.ALIGN_CENTER);
        c1.setBackgroundColor(BaseColor.GRAY);

        table1.addCell(c1);

        table1.setHeaderRows(1);

        table1.addCell(new Phrase("A. Product Cost", blackNormalFont));

        c1 = new PdfPCell(new Phrase(
                CustomFormat.NUMBER_0.format(23233223), blackNormalFont));
        c1.setHorizontalAlignment(Element.ALIGN_RIGHT);
        table1.addCell(c1);

        table1.addCell(new Phrase("1. Processing Fees", blackNormalFont));
        c1 = new PdfPCell(new Phrase(
                CustomFormat.NUMBER_0.format(3232332), blackNormalFont));
        c1.setHorizontalAlignment(Element.ALIGN_RIGHT);
        table1.addCell(c1);


        document.add(table1);

        document.close();
