Java如何在iText中旋转单元格内容？
您可以使用com.itextpdf.text.pdf.PdfPCell的setRotation()方法设置单元格内容的旋转度。有效的轮播选项0，90，180和270。
package org.nhooo.example.itextpdf;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Phrase;
import com.itextpdf.text.pdf.PdfPCell;
import com.itextpdf.text.pdf.PdfPTable;
import com.itextpdf.text.pdf.PdfWriter;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
public class TableCellRotation {
public static void main(String[] args) {
Document doc = new Document();
try {
PdfWriter.getInstance(doc, new FileOutputStream("TableCellRotate.pdf"));
doc.open();
PdfPTable table = new PdfPTable(3);
PdfPCell cell1 = new PdfPCell(new Phrase("Cell 1 - 90"));
//90度旋转
cell1.setRotation(90);
table.addCell(cell1);
PdfPCell cell2 = new PdfPCell(new Phrase("Cell 2 - 180"));
//180度旋转
cell2.setRotation(180);
table.addCell(cell2);
PdfPCell cell3 = new PdfPCell(new Phrase("Cell 3 - 270"));
//旋转270度
cell3.setRotation(270);
table.addCell(cell3);
table.completeRow();
doc.add(table);
} catch (DocumentException | FileNotFoundException e) {
e.printStackTrace();
} finally {
doc.close();
}
}
