2014年4月1日周二 晴--关于4G的某任务，Excel读取

其他 2018-09-14 03:37:48 阅读次数: 0
 今天接到一个任务是12个Excel文件要Copy到JSP文件中，要我”ACV“吗？一个没复制完就受不了这种无聊的工作，果断换别的方式。
用程序解决！但是我不知道怎样按行去读Excel表格的数据，百度一下吧。文件读取好像答案不是我想要的结果。好吧，搜一下Java读取Excel吧，这个是我要的方法了。
import java.io.File;
import jxl.Sheet;
import jxl.Workbook;
/**
 * 注意：
1.有空能输出空列、空行
 * 2.编码问题
 * */
public class ReadExcel {
 public static void main(String[] args) throws Exception{
  Workbook workbook = Workbook.getWorkbook(new File("F:/asia/excelorder/panjin.xls"));//文件路径
  Sheet sheet[] = workbook.getSheets();
  String lab = null;
  System.out.println("<table cellspacing=\"0\" cellpadding=\"0\" class=\"info_4g_table4\">");
  for(int a=0;a<sheet.length;a++){
   for(int i=0;i<sheet[a].getRows();i++){
    System.out.print("<tr>");
    for(int j=0;j<sheet[a].getColumns();j++){
     lab = sheet[a].getCell(j,i).getContents();
     if(null!=lab&&!lab.equals("")){
      if(i==0){
       System.out.print("<th>"+lab+"</th>");
      }else{
       System.out.print("<td>"+lab+"</td>");
      }
     }
    }
    System.out.println("</tr>");
   }
  }
  System.out.print("</table>");
 }
} 
暂时用这个 程序先完成任务再说，本来打算回来讲代码写一下完善一下，计划赶不上变化呀,只能改天了。悲催的上班要在路上消耗1:30小时，下班回家吃完饭9:00多了。

今天又查了一些东西，补充完整Excel文件读取。下载jexcelapi或者poiapi会有Demo和相关文档。
使用POI存在的问题：
1、整数数字变成了浮点类型；
2、代码生成table的属性时，浏览器兼容性问题，在FireFox里乱了，IE8、Google Chrome没问题，呵~呵~
<table width="100%" style="border:1px solid #000;border-width:1px 0 0 1px;margin:2px 0 2px 0;border-collapse:collapse;">
<tr height="28" style="border:1px solid #000;border-width:0 1px 1px 0;margin:2px 0 2px 0;">
<td style="border:1px solid #000; border-width:0 1px 1px 0;margin:2px 0 2px 0;  background-color:#99ccff;  color:#000000;  font-weight:700;  font-size: 100%;" align="center" valign="center" width="58"  colspan="0" rowspan="0">序号</td>

</tr>
<tr height="17" style="border:1px solid #000;border-width:0 1px 1px 0;margin:2px 0 2px 0;">
