PdfTable不会被添加到我的文档 [英] PdfTable isn't added to my document
问题描述
这里的code:
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,没有表被添加到文档的。只有段落。任何想法?
When I open the generated PDF file, no table is added to the document at all. Only the paragraphs are. Any ideas?
推荐答案
您有14列上创建一个表,但只添加一个。在 PdfPTable
您只需添加单元格中创建行。如果加入的细胞数是等于预期列数,行被创建。所以,如果你只添加一个单元格,没有行创建。
You create a table with 14 columns, but only add one. In PdfPTable
you create rows by just adding cells. If number of cells added is equal to the expected column number, a row is created. So if you only add one cell, no row is created.
此外,您可以使用 COLSPAN = 2
,所以你只需要在每行增加7列。
Furthermore, you use ColSpan = 2
, so you only need to add 7 columns per row.
我改变了 ROWSPAN
1,因为它没有工作时,这里所有的细胞rowspanned,它没有任何意义,反正它跨越了,所以。 ..
I changed RowSpan
to 1 as it didn't work well here when all the cells were rowspanned, it didn't make sense to have it spanned anyway, so...
下面是我修改它创建一个单独的行:
Here's my modification which creates a single row:
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);
}
