通过工具类jxl编写的excel报表工具类，使得生成excel时更加方便，这也是本人总结多次，到现在为止（2011-10）的版本！

示例：
public static void main(String[] args){
/**
* 生成Excel报表
* **/
short tableBeginColumNum = 0;
String nowDate = TimeOperate.getNowTime("yyyy-MM-dd");
XlsCreateExport createExcelReport = new XlsCreateExport("工作情况报表("+nowDate+")");
int tableColumnCount = 4;
createExcelReport.creatRowMergeCell(1, tableBeginColumNum, (short)tableColumnCount, createExcelReport.getCellTableNameStyle(), "工作情况报表 -- "+nowDate);
List<String[]> headerList = new ArrayList();
headerList.add(new String[]{"分组","",""});
headerList.add( new String[]{"工作区县","",""});
headerList.add(new String[]{"拟发整改通知数 ","",""});
headerList.add( new String[]{"督检通知数 ","",""});
createExcelReport.createTrValues(tableBeginColumNum, createExcelReport.getCellTitleStyle(), headerList);
List<String[]> countList = new ArrayList();
headerList.add(new String[]{"合计","2",""});
headerList.add( new String[]{"13","",""});
headerList.add(new String[]{"35","",""});
createExcelReport.createTrValues(tableBeginColumNum, countList);
List<String[]> elementList = new ArrayList();
headerList.add(new String[]{mergeKey+"朱斌忠组","大渡口区","2","5"});
headerList.add( new String[]{mergeKey+"朱斌忠组","渝中区","5", "25"});
headerList.add(new String[]{mergeKey+"余伟国组","渝中区 ","23", "29"});
createExcelReport.createMergeRowsData(tableBeginColumNum, elementList);
// createExcelReport.localSaveReport("f:/test.xls");
/**********************************************/
}
报表生成结果：
