以下是代码:

public void PrintBoletin(int studentId, int gradeParaleloId)
{
    StudentRepository studentRepo = new StudentRepository();
    var student = studentRepo.FindStudent(studentId);
    int rowHeight = 20;

    string filePath = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) + "\\Boletin.pdf";
    Document document = new Document(PageSize.LETTER);
    BaseFont baseFont = BaseFont.CreateFont(BaseFont.COURIER, BaseFont.CP1250, BaseFont.EMBEDDED);
    Font font = new Font(baseFont, 8);

    PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(filePath, FileMode.Create));
    document.Open();

    GradeParaleloRepository paraRep = new GradeParaleloRepository();
    var gra = paraRep.FindGradeParalelo(gradeParaleloId);
    Paragraph p = new Paragraph(new Phrase("Boletin de Notas - Gestion " + DateTime.Now.Year + " \n " + gra.Grade.Name + " " + gra.Name + "\n Colegio Madre Vicenta Uboldi \n " + DateTime.Now, font));
    Paragraph p2 = new Paragraph(new Phrase("Alumno: " + student.StudentId + " - " + student.LastNameFather + " " + student.LastNameMother + ", " + student.Name, font));

    document.Add(p);
    document.Add(p2);

    PdfPTable table = new PdfPTable(14); //14 Column table.
    table.TotalWidth = 550f;
    float[] widths = new float[] { 1.4f, 0.18f, 0.18f, 0.18f, 0.18f, 0.18f, 0.18f, 0.18f, 0.18f, 0.18f, 0.18f, 0.18f, 0.18f, 0.18f };
    table.SetWidths(widths);

    PdfPCell materia = new PdfPCell(new Phrase("MATERIA", font));
    materia.Rowspan = 2;
    materia.Colspan = 2;
    materia.HorizontalAlignment = 1;
    materia.VerticalAlignment = 1;
    table.AddCell(materia);


    table.SpacingBefore = 20f;
    table.SpacingAfter = 20f;

    document.Add(table);
    document.Close();

    Process.Start(filePath);
}

当我打开生成的PDF文件时,根本没有表格添加到文档中。只有段落。有什么想法吗?

答案 0 :(得分:2)

您创建一个包含14列的表,但只添加一列。在PdfPTable中,您只需添加单元格即可创建行。如果添加的单元格数等于预期的列数,则会创建一行。因此,如果您只添加一个单元格,则不会创建任何行。

此外,您使用ColSpan = 2,因此每行只需添加7列。

我将RowSpan更改为1,因为当所有单元格都是排版时,它在这里工作不正常,无论如何都没有任何意义,所以...

这是我的修改,它创建了一行:

for (int i = 0; i < widths.Length / 2; i++)
{
    PdfPCell materia = new PdfPCell(new Phrase("MATERIA", font));
    materia.Rowspan = 1;
    materia.Colspan = 2;
    materia.HorizontalAlignment = 1;
    materia.VerticalAlignment = 1;
    table.AddCell(materia);
}
