Question

我有一个生成文本报告的功能。我从数据库中获取文档文本列表，然后创建PDF报告。 PDF报告格式应如下

logo(top left).........some static text about company (top right)

[header information that is......................................
.........................different for each document in the list]  

[.....................document text.............................]

date(bottom left)              page count(bottom right)

文档文本可能会运行多个页面，在这种情况下，该文档的标题信息会重复。并且，如果文档文本运行第二页并在页面中间终止，我们将在新页面上启动下一个文档。这是我的尝试：

public static void printDocument(List<PdfData> lst, ref MemoryStream memoryStream)
{
        iTextSharp.text.Font baseFontBig = new     iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 12f, iTextSharp.text.Font.BOLD, iTextSharp.text.BaseColor.BLACK);

        iTextSharp.text.Document document = new iTextSharp.text.Document(PageSize.LETTER, 40, 25, 30, 30);
        PDFEvents e = new PDFEvents();
        PdfWriter pw = PdfWriter.GetInstance(document, memoryStream);
        pw.PageEvent = e;
        document.Open();

        for (int i = 0; i < lst.Count; i++)
        {
            PdfPTable mainTable = new PdfPTable(2);
            PdfPTable outerTable = new PdfPTable(4);
            PdfPTable contentTable = new PdfPTable(1);

            mainTable.KeepTogether = true;

            outerTable.WidthPercentage = 50;
            outerTable.KeepTogether = false;
            outerTable.TotalWidth = 550f;
            float[] sglTblHdWidths = new float[4];
            sglTblHdWidths[0] = 5f;
            sglTblHdWidths[1] = 15f;
            sglTblHdWidths[2] = 5f;
            sglTblHdWidths[3] = 5f;
            outerTable.SetWidths(sglTblHdWidths);
            outerTable.LockedWidth = true;
            contentTable.LockedWidth = true;
            outerTable.KeepTogether = true;

            contentTable.WidthPercentage = 90;
            contentTable.KeepTogether = false;
            contentTable.TotalWidth = 800f;
            contentTable.SpacingBefore = 30f;

            string documentIdentifier = lst[i].patient;
            string documentStatus =lst[i].documentStatus;



            StringBuilder sb = new StringBuilder();

            sb.Append(lst[i].documentText);



            iTextSharp.text.Paragraph documentStatusP = new iTextSharp.text.Paragraph(documentStatus, new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.COURIER, 12, iTextSharp.text.Font.BOLD, iTextSharp.text.BaseColor.BLACK));
            iTextSharp.text.Paragraph patient = new iTextSharp.text.Paragraph(documentIdentifier, new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.COURIER, 12, iTextSharp.text.Font.BOLD, iTextSharp.text.BaseColor.BLACK));
            iTextSharp.text.Paragraph content = new iTextSharp.text.Paragraph(sb.ToString(), new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.COURIER, 10));
            iTextSharp.text.Paragraph empty = new iTextSharp.text.Paragraph("", new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.COURIER, 12));



            #region Content

             PdfPCell contentCell = new PdfPCell(content);
             contentCell.Border =1;
             contentCell.VerticalAlignment = Element.ALIGN_TOP;
             contentCell.HorizontalAlignment = Element.ALIGN_LEFT;

             contentTable.AddCell(contentCell);
            #endregion



            PdfPCell firstHeader = new PdfPCell(empty);
            firstHeader.Border = 0;
            firstHeader.FixedHeight = 17f;
            outerTable.AddCell(firstHeader);             

            PdfPCell secondHeader = new PdfPCell(patient);
            secondHeader.Border = 0;
            secondHeader.FixedHeight = 17f;
            secondHeader.VerticalAlignment = 2;
            outerTable.AddCell(secondHeader);

            PdfPCell thirdHeader = new PdfPCell(documentStatusP);
            thirdHeader.Border = 0;
            thirdHeader.FixedHeight = 17f;
            thirdHeader.HorizontalAlignment = 1;
            thirdHeader.VerticalAlignment = 2;
            outerTable.AddCell(thirdHeader);

            PdfPCell forthHeader = new PdfPCell(empty);
            forthHeader.Border = 0;
            forthHeader.FixedHeight = 17f;
            outerTable.AddCell(forthHeader);


            PdfPCell outerTblCell = new PdfPCell(outerTable);
            outerTblCell.Border = 0;

            PdfPCell contentTblCell = new PdfPCell(contentTable);
            contentTblCell.Border = 0;


            mainTable.AddCell(outerTblCell);
            mainTable.AddCell(contentTblCell);

            document.Add(mainTable);
            if (i != lst.Count - 1)
                document.NewPage();
        }

        document.Close();

    }

这显示了报告和所有必需的值，但在内容表中，当文档文本的行很长时，它会在页面的边距之外运行，而您无法看到它。有没有办法更好地实现这一目标？谢谢！

Answer 1

我首先修复页面的边距，如下所示：

const float leftMargin = 34;
const float rightMargin = 34;
const float topMargin = 134;
const float bottomMargin = 36;

var document = new Document(PageSize.A4, leftMargin, rightMargin, topMargin, bottomMargin);

然后我修复了表格的宽度。在我的情况下，文档在纵向A4页面上，所以我知道页面的最大宽度，并可以减去边距。我像这样构建表：

private PdfPTable CreateTable()
{
    const float tableWidth = 527;

    var table = new PdfPTable(1)
    {
        HorizontalAlignment = Element.ALIGN_LEFT,
        TotalWidth = tableWidth,
        LockedWidth = true,
        SplitLate = true,
        SplitRows = true  
    };

    return table;
}

文本未使用iText5 for .NET包装在表格单元格中
