Why doesn't getDefaultCell().setBorder(PdfPCell.NO_BORDER) have any effect?

For some reason table.getDefaultCell().setBorder(PdfPCell.NO_BORDER) has no effect: my table has still borders.

Here is my code:

PdfPTable table = new PdfPTable(new float[] { 1, 1, 1, 1, 1 });
table.getDefaultCell().setBorder(PdfPCell.NO_BORDER);
Font tfont = new Font(Font.FontFamily.UNDEFINED, 10, Font.BOLD);
table.setWidthPercentage(100);
PdfPCell cell;
cell = new PdfPCell(new Phrase("Menge", tfont));
table.addCell(cell);
cell = new PdfPCell(new Phrase("Beschreibung", tfont));
table.addCell(cell);
cell = new PdfPCell(new Phrase("Einzelpreis", tfont));
table.addCell(cell);
cell = new PdfPCell(new Phrase("Gesamtpreis", tfont));
table.addCell(cell);
cell = new PdfPCell(new Phrase("MwSt", tfont));
table.addCell(cell);
document.add(table);
Do you have any idea what I am doing wrong?

You are mixing two different concepts.

Concept 1: you define every Cell (no PdfPCell in iText 7) manually, for instance:

Cell cell = new Cell()
    .add(new Paragraph("Menge"))
    .setFont(tfont)
    .setBorder(Border.NO_BORDER);

In this case, you define every aspect, every property of the cell on the cell itself.

Concept 2: you allow iText to create the Cell implicitly, for instance:

table.addCell("Adding a String");
table.addCell(new Paragraph("Adding a paragraph"));

In this case, you can define properties at the level of the default cell. These properties will be used internally when iText creates a Cell in your place.

Conclusion: either you define the border for all the Cell instances separately, or you let iText create the Cell instances in which case you can define the border at the level of the default cell. If you choose the second option, you can adapt your code like this:

Table table = new Table(new float[] { 1, 1, 1, 1, 1 });
table.setProperty(Property.BORDER, Border.NO_BORDER);
PdfFont tfont = PdfFontFactory.createFont(FontConstants.HELVETICA_BOLD);
table.setWidthPercent(100);
table.addCell(new Paragraph("Menge")).setFont(tfont);
table.addCell(new Paragraph("Beschreibung")).setFont(tfont);
table.addCell(new Paragraph("Einzelpreis")).setFont(tfont);
table.addCell(new Paragraph("Gesamtpreis")).setFont(tfont);
table.addCell(new Paragraph("MwSt")).setFont(tfont);
document.add(table);

This decision was made by design, based on experience: it offers the most flexible to work with cells and properties.
