iTextSharp multiple lines in PdfPCell one under another

问题

I am using iTextSharp to create table in PDF document. I need several lines inside table cell to appear one under another like this:

First line text
   Second Line Text
   Third Line Text
Fourth line text

Some times with extra line like this :

First line text

   Second Line Text
   Third Line Text
Fourth line text

I have tried several approaches, with Paragraphs, Chunks, Phrases, did research online but still can not get this result. Please help. Also, how to make columns to adjust width dynamically to content ? (not wrapping) Thank you

If you need to align at the text level you'll need to switch to a fixed-width font. But if you're just looking to indent you can just add spaces to new lines within a paragraph:

var p = new Paragraph();
p.Add("First line text\n");
p.Add("    Second line text\n");
p.Add("    Third line text\n");
p.Add("Fourth line text\n");
myTable.AddCell(p);

You could also get complicated and use a sub-table if you need more control:

var subTable = new PdfPTable(new float[] { 10, 100 });                        
subTable.AddCell(new PdfPCell(new Phrase("First line text")) { Colspan = 2, Border = 0 });
subTable.AddCell(new PdfPCell() { Border = 0 });
subTable.AddCell(new PdfPCell(new Phrase("Second line text")) {  Border = 0 });
subTable.AddCell(new PdfPCell() { Border = 0 });
subTable.AddCell(new PdfPCell(new Phrase("Third line text")) { Border = 0 });
subTable.AddCell(new PdfPCell(new Phrase("Fourth line text")) { Colspan = 2, Border = 0 });
myTable.AddCell(subTable);

Though pretty tedious, but for setting font, following seem to work:

Font myFont = FontFactory.GetFont("Arial", 8, Font.NORMAL);

string line1 = "First line of text" + "\n";                     
string line2= "Second line of text" + "\n";
string line3= "   Third Line of text";

Paragraph p1 = new Paragraph();
Phrase ph1 = new Phrase(line1, myFont);
Phrase ph2 = new Phrase(line2, myFont);
Phrase ph3 = new Phrase(line3, myFont);

p1.Add(ph1);
p1.Add(ph2);
p1.Add(ph3);

PdfPCell mycell = new PdfPCell(p1);

You can also do it the following way ..

var xstring = "Your first line \n Your 2nd line";
Phrase p = new Phrase();
p.Add(new Chunk(xstring, yourFontFace));

I text will notice the new line return code and render your phrase on two separate lines.

Your first line

Your 2nd line

Cheers
