Java如何在iText中创建嵌套表？
本示例向您展示如何在iText中创建嵌套表。要创建嵌套表，您可以com.itextpdf.text.pdf.PdfPTable使用com.itextpdf.text.pdf.PdfPCell的addElement()方法将对象添加到单元格中。
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 TableNestedDemo {
public static void main(String[] args) {
Document doc = new Document();
try {
PdfWriter.getInstance(doc, new FileOutputStream("TableNestedDemo.pdf"));
doc.open();
PdfPTable table = new PdfPTable(3);
PdfPCell cell1 = new PdfPCell(new Phrase("Cell 1"));
PdfPCell cell2 = new PdfPCell(new Phrase("Cell 2"));
PdfPCell cell3 = new PdfPCell(new Phrase("Cell 3"));
PdfPTable nestedTable = new PdfPTable(2);
nestedTable.addCell(new PdfPCell(new Phrase("Nested 1")));
nestedTable.addCell(new PdfPCell(new Phrase("Nested 2")));
cell3.addElement(nestedTable);
table.addCell(cell1);
table.addCell(cell2);
table.addCell(cell3);
doc.add(table);
} catch (DocumentException | FileNotFoundException e) {
e.printStackTrace();
} finally {
doc.close();
}
}
