This is done using cell events.

Make sure that you don't add any "automated" borders to the cell, but draw the borders yourself in a cell event:

table.DefaultCell.Border  = PdfPCell.NO_BORDER;
table.DefaultCell.CellEvent = new RoundedBorder();

The RoundedBorder class would then look like this:

class RoundedBorder : IPdfPCellEvent {
  public void CellLayout(PdfPCell cell, Rectangle rect, PdfContentByte[] canvas) {
    PdfContentByte cb = canvas[PdfPTable.BACKGROUNDCANVAS];
    cb.RoundRectangle(
      rect.Left + 1.5f,
      rect.Bottom + 1.5f,
      rect.Width - 3,
      rect.Height - 3, 4
    );
    cb.Stroke();
  }
}

You can of course fine-tune the values 1.5, 3 and 4 to get different effects.
