JXCELL实例学习与研究（一） 之 打开EXCEL并备份 JS中插入数据与显示柱状图
JXCELL是处理EXCEL的JAR，可以生成报表，带图片，动态的，此外经过调研，还可以在客户不安装OFFICE的情况下使用。
最近参加了一个项目，TMA流控设备，简称T02，这里我将JXCELL的学习过程记录下来。
首先，我用的JXCELL是破解版，下载地址如下：
http://download.csdn.net/detail/opzoonzhuzhengke/4060860
很需要注意的是，我的JDK版本一开始是JDK7，然后没有跑起程序，后来换成JDK6了。所以请注意，JDK7不支持我所提供的JXCELL的JAR包！
我使用的MYECLIPSE默认是JDK7的，所以，我学习了如下网页的知识：
http://wenku.baidu.com/view/80732575a417866fb84a8e5b.html
直接在MYECLIPSE里的PREFERENCES配置出了JDK1.6的环境
第一个代码。这个代码得作用是打开一个本地的EXCEL文件， 然后将其保存成另外一个文件名的文件
import com.jxcell.*;
import com.jxcell.designer.Designer;
import java.io.IOException;
public class OpenXML
{
public static void main(String args[])
{
View m_view;
try
{
m_view =new View();
m_view.readXLSX("D:\\EXCEL\\format.xlsx");
m_view.writeXLSX("D:\\EXCEL\\out.xlsx");
Designer.newDesigner(m_view);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
本博文的第二个实例，在JS中使用JXCELL
这里案例显示了JXCELL的SHEET，滚动条，输入栏等等的显示与不显示，主要使用0、1和FALSE，TRUE制作的。就是熟悉JXCELL往EXCEL里如何插入数据、显示柱状图的操作的
