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*************/
WritableWorkbookworkbook=Workbook.createWorkbook(newFile("d:/test.xls"));
/***//************创建工作表*************/
WritableSheetsheet=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

wcf_title.setBorder(Border.NONE,BorderLineStyle.THIN);//线条
