jxl使用例子

package testExcel;

import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import jxl.Workbook;
import jxl.format.CellFormat;
import jxl.format.Colour;
import jxl.write.Label;
import jxl.write.WritableCellFormat;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;

public class TestExcel {

	public static void main(String[] args) {
		new TestExcel().generateNewByModal();
	}
	
	/**
	 * 完全新建一个新的Workbook
	 */
	public void createNew() {
		// 创建存储文件
		try {
			String tempDownFullName = "d:/test.xls";
			WritableWorkbook workbook = Workbook.createWorkbook(new File(
					tempDownFullName));

			WritableSheet sheet = workbook.createSheet("sheet1", 0);

			Label label = null;

			WritableCellFormat wcf = new WritableCellFormat();
			wcf.setBackground(Colour.RED);

			label = new Label(1, 0, "biaoti", wcf);

			// sheet添加内容
			sheet.addCell(label);

			// wb保存
			workbook.write();
			workbook.close();

		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	
	
	
	/**
	 * 根据模板新建一个workbook
	 */
	public void generateNewByModal() {

		try {
			WritableWorkbook writableWorkbook = null;

			String tempModalFullName = "d:/test.xls";
			String newFileFullName = "d:/testNew.xls";

			// 取得模板文件流
			InputStream input = new FileInputStream(tempModalFullName);
			Workbook modalbook = Workbook.getWorkbook(input);

			// 生成新的workbook
			writableWorkbook = Workbook.createWorkbook(
					new File(newFileFullName), modalbook);

			// 创建存储文件
			// workbook = Workbook.createWorkbook(new File(tempDownFullName));

			WritableSheet sheet = writableWorkbook.getSheet("sheet1");

			Label label = null;

			CellFormat cf = sheet.getCell(1, 0).getCellFormat();

			// sheet.getCell(1, 0).
			WritableCellFormat wcf = new WritableCellFormat(cf);

			label = new Label(1, 0, "biaoti", wcf);
			label.setCellFormat(cf);
			wcf.setBackground(Colour.BLUE);
			sheet.addCell(label);

			writableWorkbook.write();
			writableWorkbook.close();

		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	}

}

 

 

需要jxl JAR包的支持，我的是1.0版本。

 

 

 

ps:发现一个讲的比较好的jxl的例子：http://yanick.iteye.com/blog/319394

ps: jxl是从0开始的(记忆技巧：程序都是从0开始的)，而excel是从1开始的
