使用Java POI生成Excel表文件的方法

// 使用Java POI
// 把要两个JAR文件放到lib/ext下
// code run against the jakarta-poi-1.5.0-FINAL-20020506.jar.
// and commons-logging-1.0.jar
例子程序:
import org.apache.poi.hssf.usermodel.*;
import java.io.FileOutputStream;

// code run against the jakarta-poi-1.5.0-FINAL-20020506.jar.
// and commons-logging-1.0.jar
public class PoiTest {

static public void main(String[] args) throws Exception {

FileOutputStream fos = new FileOutputStream("d://foo.xls");
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet s = wb.createSheet();
wb.setSheetName(0, "Matrix");
for(short i=0; i<50; i++) {
HSSFRow row = s.createRow(i);
for(short j=0; j<50; j++) {
HSSFCell cell = row.createCell(j);
cell.setCellValue(""+i+","+j);
}
}
wb.write(fos);
fos.close();
}
}
