How to create a nested column?
How can I create a table that looks like the table in the following screen shot:
This is my code so far:
var subTable2 = new PdfPTable(new float[] { 100, 100, 100, 100, 100, 100,100,100 }); subTable2.TotalWidth = 510f; subTable2.LockedWidth = true; subTable2.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER; subTable2.AddCell(new Phrase("Examination", time51)); subTable2.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER; subTable2.AddCell(new Phrase("Board", time51)); subTable2.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER; subTable2.AddCell(new Phrase("Month and Year of Passing", time51)); subTable2.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER; subTable2.AddCell(new PdfPCell(new Phrase("Mark", time51))); PdfPTable nested = new PdfPTable(1); nested.AddCell(""); nested.AddCell("Obtained"); nested.AddCell("Out of"); PdfPCell nesthousing = new PdfPCell(nested); nesthousing.Padding = 0f; subTable2.AddCell(nesthousing); subTable2.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER; subTable2.AddCell(new Phrase("Percentage", time51)); subTable2.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER; subTable2.AddCell(new Phrase("Calss/Grade", time51)); doc.Add(subTable2);
Please take a look at SimpleTable12. It creates a table that looks like this: simple_table12.pdf
Table example
You could still fine-tune the height of the cells by using a padding or by introducing descender/ascender info, but those are details. What matters is: how to organize the cells?
I've written this small convenience method:
public PdfPCell createCell(String content, int colspan, int rowspan, int border) {
PdfPCell cell = new PdfPCell(new Phrase(content, font));
cell.setColspan(colspan);
cell.setRowspan(rowspan);
cell.setBorder(border);
cell.setHorizontalAlignment(Element.ALIGN_CENTER);
return cell;
}
You pass some content, a colspan, a rowspan and border info and it creates you the PdfPCell
you need. This allows us to create code that is easier to read:
public void createPdf(String dest) throws IOException, DocumentException {
font = new Font(FontFamily.HELVETICA, 10);
Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream(dest));
document.open();
PdfPTable table = new PdfPTable(8);
table.setWidthPercentage(100);
table.addCell(createCell("Examination", 1, 2, PdfPCell.BOX));
table.addCell(createCell("Board", 1, 2, PdfPCell.BOX));
table.addCell(createCell("Month and Year of Passing", 1, 2, PdfPCell.BOX));
table.addCell(createCell("", 1, 1, PdfPCell.TOP));
table.addCell(createCell("Marks", 2, 1, PdfPCell.TOP));
table.addCell(createCell("Percentage", 1, 2, PdfPCell.BOX));
table.addCell(createCell("Class / Grade", 1, 2, PdfPCell.BOX));
table.addCell(createCell("", 1, 1, PdfPCell.BOX));
table.addCell(createCell("Obtained", 1, 1, PdfPCell.BOX));
table.addCell(createCell("Out of", 1, 1, PdfPCell.BOX));
table.addCell(createCell("12th / I.B. Diploma", 1, 1, PdfPCell.BOX));
table.addCell(createCell("", 1, 1, PdfPCell.BOX));
table.addCell(createCell("", 1, 1, PdfPCell.BOX));
table.addCell(createCell("Aggregate (all subjects)", 1, 1, PdfPCell.BOX));
table.addCell(createCell("", 1, 1, PdfPCell.BOX));
table.addCell(createCell("", 1, 1, PdfPCell.BOX));
table.addCell(createCell("", 1, 1, PdfPCell.BOX));
table.addCell(createCell("", 1, 1, PdfPCell.BOX));
document.add(table);
document.close();
}
As you can see, it's a matter of calculating the correct colspan
and rowspan
values, and applying the correct borders.
