Issue747: fix wrong layout of generating a table with alignment setting #749

Description of the new Feature/Bugfix

The strange layout or endless loop is caused by wrong position of the first line in cell which sets alignment not as TOP. After searching the codes deeper, I find it forgets to change contentHeight after modifying line.height with adding correct alignment space. In this way, I just add the missing part on contentHeight for the first line and it works perfectly!

public static void test() throws FileNotFoundException {
	Document document = new Document(PageSize.A4);
	PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("test.pdf"));
	Table table = new Table(2);
	Cell cell = new Cell("any text\nany text\nany text\nany text\nany text\nany text");
	cell.setVerticalAlignment(VerticalAlignment.BOTTOM);
	table.addCell(cell);
	StringBuilder largeStr = new StringBuilder();
	for (int i = 0; i < 45; i++) {
		largeStr.append(String.format("this is to test-> row %d\n", i));
	}
	Cell cell2 = new Cell(new Phrase(largeStr.toString()));
	table.addCell(cell2);
	document.open();
	document.add(table);
	document.close();
