jsp生成复杂数据格式Excel文件

package beans.excel;import java.io.IOException;import java.io.OutputStream;import java.util.Calendar;import java.util.Date;import jxl.Workbook;import jxl.write.Boolean;import jxl.write.DateFormats;import jxl.write.DateTime;import jxl.write.Label;import jxl.write.Number;import jxl.write.WritableCellFormat;import jxl.write.WritableSheet;import jxl.write.WritableWorkbook;import jxl.write.WriteException;public class ComplexDataExcelWrite {    public void createExcel(OutputStream os) throws WriteException,IOException {        //创建工作薄
        WritableWorkbook workbook = Workbook.createWorkbook(os);        //创建新的一页
        WritableSheet sheet = workbook.createSheet("First Sheet", 0);        //创建要显示的具体内容
        Label formate = new Label(0,0,"数据格式");
        sheet.addCell(formate);
        Label floats = new Label(1,0,"浮点型");
        sheet.addCell(floats);

        sheet.addCell(bools);        //日期型数据
        Calendar c = Calendar.getInstance();
        Date date = c.getTime();
        WritableCellFormat cf1 = new WritableCellFormat(DateFormats.FORMAT1);
        DateTime dt = new DateTime(4,1,date,cf1);
        sheet.addCell(dt);        //把创建的内容写入到输出流中，并关闭输出流        workbook.write();
        workbook.close();
        os.close();

 三、生成复杂布局和样式的Excel文件

package beans.excel;import java.io.IOException;import java.io.OutputStream;import java.util.Calendar;import java.util.Date;import jxl.Workbook;import jxl.format.Colour;import jxl.format.UnderlineStyle;import jxl.write.Boolean;import jxl.write.DateFormats;import jxl.write.DateTime;import jxl.write.Label;import jxl.write.Number;import jxl.write.WritableCellFormat;import jxl.write.WritableFont;import jxl.write.WritableSheet;import jxl.write.WritableWorkbook;import jxl.write.WriteException;public class MutiStyleExcelWrite {    public void createExcel(OutputStream os) throws WriteException,IOException {        //创建工作薄
        WritableWorkbook workbook = Workbook.createWorkbook(os);        //创建新的一页
        WritableSheet sheet = workbook.createSheet("First Sheet", 0);        //构造表头
        sheet.mergeCells(0, 0, 4, 0);//添加合并单元格，第一个参数是起始列，第二个参数是起始行，第三个参数是终止列，第四个参数是终止行
        WritableFont bold = new WritableFont(WritableFont.ARIAL,10,WritableFont.BOLD);//设置字体种类和黑体显示,字体为Arial,字号大小为10,采用黑体显示
        WritableCellFormat titleFormate = new WritableCellFormat(bold);//生成一个单元格样式控制对象

        titleFormate.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);//单元格的内容垂直方向居中
        Label title = new Label(0,0,"JExcelApi支持数据类型详细说明",titleFormate);

        color.setColour(Colour.GOLD);//设置字体颜色为金黄色
        WritableCellFormat colorFormat = new WritableCellFormat(color);
        Label formate = new Label(0,1,"数据格式",colorFormat);
        sheet.addCell(formate);

        sheet.addCell(dates);
        
        Label example = new Label(0,2,"数据示例",colorFormat);
        sheet.addCell(example);        //浮点数据        //设置下划线
        WritableFont underline= new WritableFont(WritableFont.ARIAL,WritableFont.DEFAULT_POINT_SIZE,WritableFont.NO_BOLD,false,UnderlineStyle.SINGLE);
        WritableCellFormat greyBackground = new WritableCellFormat(underline);
        greyBackground.setBackground(Colour.GRAY_25);//设置背景颜色为灰色
        Number number = new Number(1,2,3.1415926535,greyBackground);
        sheet.addCell(number);        //整形数据
        WritableFont boldNumber = new WritableFont(WritableFont.ARIAL,10,WritableFont.BOLD);//黑体

        DateTime dt = new DateTime(4,2,date,boldDateFormate);
        sheet.addCell(dt);        //把创建的内容写入到输出流中，并关闭输出流        workbook.write();
        workbook.close();
        os.close();
