How to provide alignment to chunk or phrases in itext?
提问by Amit Kumar
I have two chunks, added in phrases and then in paragraph.
我有两个块，先在短语中添加，然后在段落中添加。
Chunk reportTitle= new Chunk("Candidate Login Report ",catFont);
Chunk divisiontitle = new Chunk("Division : \t\t"+divisionName);
Phrase phrase = new Phrase();
phrase.add(reportTitle);
phrase.add(divisiontitle);
Paragraph para = new Paragraph();
para.add(phrase);
I have to set chunk divisiontitleto right aligned. Is there any provision to do this in iIext?
我必须将块设置divisiontitle为右对齐。iIext 中是否有任何规定可以做到这一点？

bajrangi,
巴杰兰吉，
You might want to use ColumnText.showTextAligned() to align your text. Try the following:
您可能想要使用 ColumnText.showTextAligned() 来对齐您的文本。请尝试以下操作：
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(filename));
PdfContentByte canvas = writer.getDirectContent();
ColumnText.showTextAligned(canvas, Element.ALIGN_RIGHT, phrase, xPosition, yPosition, 0);
Cheers!
干杯!

You really answered yourself in your comment.
你真的在你的评论中回答了你自己。
Chunk reportTitle= new Chunk("Candidate Login Report ",catFont);
Chunk divisiontitle = new Chunk("Division : \t\t"+divisionName);
Phrase phrase = new Phrase();
phrase.add(reportTitle);
phrase.add(divisiontitle);
Paragraph para = new Paragraph();
para.add(phrase);
para.setAlignment(Element.ALIGN_RIGHT);
Then you can add it to any cell and it will be correctly aligned.
然后你可以将它添加到任何单元格，它会正确对齐。
