jexcelapi是一个开源项目,主要用来操作excel.
主页地址:
http://www.andykhan.com/jexcelapi/
现在做一个项目用到了它,根据不同的公司生成不同的文件夹,
在相应的文件夹下生成对应的xls. 这里只帖出生成xls部分核心代码:
 public void generateXls()
   {
 try
  {
/** *//** **********创建工作簿************ */
WritableWorkbook workbook = Workbook.createWorkbook(new File("d:/test.xls"));
/** *//** **********创建工作表************ */
WritableSheet sheet = workbook.createSheet("工作表名称", 0);
/** *//** *********设置列宽**************** */
sheet.setColumnView(0, 15); // 第1列
sheet.setColumnView(1, 18); // 第2列
sheet.setColumnView(2, 13);
sheet.setColumnView(3, 13);
sheet.setColumnView(4, 15);
sheet.setColumnView(5, 15);
//设置行高
sheet.setRowView(0, 600, false);
sheet.setRowView(1, 400, false);
sheet.setRowView(7, 400, false);
//设置页边距
sheet.getSettings().setRightMargin(0.5);
//设置页脚
sheet.setFooter("", "", "测试页脚");
/** *//** ************设置单元格字体************** */
//字体
WritableFont NormalFont = new WritableFont(WritableFont.ARIAL, 10);
WritableFont BoldFont = new WritableFont(WritableFont.ARIAL, 14,
WritableFont.BOLD);
WritableFont tableFont = new WritableFont(WritableFont.ARIAL, 12,
WritableFont.NO_BOLD);
WritableFont baodanFont = new WritableFont(WritableFont.ARIAL, 10,
WritableFont.BOLD);
/** *//** ************以下设置几种格式的单元格************ */
// 用于标题
WritableCellFormat wcf_title = new WritableCellFormat(BoldFont);
wcf_title.setBorder(Border.NONE, BorderLineStyle.THIN); // 线条
wcf_title.setVerticalAlignment(VerticalAlignment.CENTRE); // 垂直对齐
wcf_title.setAlignment(Alignment.CENTRE); // 水平对齐
wcf_title.setWrap(true); // 是否换行
// 用于表格标题
WritableCellFormat wcf_tabletitle = new WritableCellFormat(
tableFont);
wcf_tabletitle.setBorder(Border.NONE, BorderLineStyle.THIN); // 线条
wcf_tabletitle.setVerticalAlignment(VerticalAlignment.CENTRE); // 垂直对齐

wcf_tabletitle.setWrap(true); // 是否换行

// 用于正文右

wcf_right.setBorder(Border.ALL, BorderLineStyle.THIN); // 线条
wcf_right.setVerticalAlignment(VerticalAlignment.CENTRE); // 垂直对齐
wcf_right.setAlignment(Alignment.RIGHT);
wcf_right.setWrap(false); // 是否换行
// 用于跨行
WritableCellFormat wcf_merge = new WritableCellFormat(NormalFont);
wcf_merge.setBorder(Border.ALL, BorderLineStyle.THIN); // 线条
wcf_merge.setVerticalAlignment(VerticalAlignment.TOP); // 垂直对齐
wcf_merge.setAlignment(Alignment.LEFT);
wcf_merge.setWrap(true); // 是否换行
