这是代码:
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,根本没有向文档添加任何表格。只有段落是。有什么想法吗?
您创建了一个包含 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号,则创建一行。因此,如果只添加一个单元格,则不会创建任何行。
此外,您使用 ColSpan = 2
,因此您只需每行添加 7 列。
我将 RowSpan
更改为 1,因为当所有单元格都跨行时,它在这里效果不佳,无论如何跨越它都没有意义,所以......
这是我创建单行的修改:
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);
}
