使用poi生成excel文�g

Vincent-chen — Tue, 25 Nov 2008 08:34:00 GMT

poi是apache基金下面的一个开源项目，在[url]http://www.apache.org/dyn/closer.cgi/jakarta/poi/[/url] 可以下蝲到poi的包
下蝲以后把解压得到的文�g加到web-inf下面的lib目录下面��可以��用了�?br />
下面先介�l�一下生成excel文�g要用的类�Q?br /> HSSFWorkbook 用于创徏excel文�g
HSSFSheet 用于创徏excel的书�?br /> HSSFRow 用于创徏一�?br /> HSSFCell 用于创徏一个单元格
HSSFCellStyle 用于创徏一个单元格的格�?br /> HSSFFont 用于创徏一个单元格的字体格�?br /> 下面用本人写的一个通用的工��L��作�ؓ例子说明一下生成文件的�Ҏ��
�Q�这里只列出部分代码�Q�详�l�的��L��附�g的源码，如果要��用附件的代码�Q�请保留原创人的名字�Q?br />

public   String createFile(List<Hashtable> hlist)//�Ҏ��传入的参数读取数据，�q�里用了范型指定参数是hashtable�c�d��的list

for(int hcount=0;hcount<hlist.size();hcount++)
{

HSSFSheet sheettemp = wb.createSheet();
wb.setSheetName(hcount,(String)ha.get("name"),(short)1);//新徏一个sheet
HSSFRow rowtitle = sheettemp.createRow((short)0);//��d��表头
       HSSFCell celltitle = rowtitle.createCell((short)0);
       celltitle.setEncoding(HSSFCell.ENCODING_UTF_16);//讄��字体�~�码
