I do the following with iText 7

Table table = ...
int NUMBER_OF_ROWS = ...
Cell cell = null;
boolean condition = true;

for (int i = 0; i < NUMBER_OF_ROWS; i++) {

    cell = new Cell().add(new Paragraph("Column 1"));
    cell.setBackgroundColor(condition ? Color.GREY: Color.WHITE);
    table.addCell(cell);

    cell = new Cell().add(new Paragraph("Column 2"));
    cell.setBackgroundColor(condition ? Color.GREY : Color.WHITE);
    table.addCell(cell);

    cell = new Cell().add(new Paragraph("Column 3"));
    cell.setBackgroundColor(condition ? Color.GREY : Color.WHITE);
    table.addCell(cell);

    condition = !condition;
}

boolean b = true;
for(PdfPRow r: table.getRows()) {
  for(PdfPCell c: r.getCells()) {
    c.setBackgroundColor(b ? BaseColor.GREY : BaseColor.WHITE);
  }
  b = !b;
}
