I am trying to set border colors of table cells. No matter what I try, the border color is not changing - it's always black! What am I doing wrong?

Here's my test code. cell1 should have a red top border and a blue bottom border:

PdfPTable table = new PdfPTable(2);
PdfPCell cell1 = new PdfPCell(new Phrase("Cell 1"));
cell1.setBorderColorTop(new BaseColor(255, 0, 0));
PdfPCell cell2 = new PdfPCell(new Phrase("Cell 2"));

Please take a look at the ColoredBorder example. It shows the solutions of your problem.

Here is a short piece of code that shows how to create a cell with different borders in iText 7:

PdfDocument pdfDoc = new PdfDocument(new PdfWriter(dest));
Document doc = new Document(pdfDoc);
Table table;
table = new Table(2);
Cell cell;
cell = new Cell().add("Cell 1");
cell.setBorderTop(new SolidBorder(Color.RED, 1));
cell.setBorderBottom(new SolidBorder(Color.BLUE, 1));
cell = new Cell().add("Cell 2");

The result looks like this:

Different cell border widths and colors
