    Home Page:http://www.extremecomponents.org

     Extreme Table是最功能强大而又Ҏ配置,扩展,自定义的Table 控g?/p>

     最紧要的功能包括排? 分页, 导出Excel, pdf和汇怅R?/p>

     springside的best CZ代码? listBook.jsp和listOrder.jsp.

基础ȝ: 

     1. ExtremeTable自带的文?/a> .

     2.Luck译的ExtremeTable官方文档中文?/a>   

1. 安装

1.1 安装原始版本

     1. ?a >http://www.extremecomponents.org 下蝲最新版

     2.把extremecomponents.jar 攑օweb-inf/lib

     3.Ҏminum, 导出excel ?导出pdf的需要，?lib下的jar copy到web-inf/lib

     4.把images里的囄攑օweb的Q意目?/p>

     5.把css文g攑ֈweb的Q意目?/p>

     6.?source/org/extremecomponents/table/core目录扑ֈextremetable.properties文g,把它复制到WEB-INF/classes里面q进行修?

     7.修改web.xml (?)?/p>

 0.2 复制SpringSide的样?/h3>

     1.Copy springside的Table Head的图Q查?/p>

     2.springside中的修改版extremecomponents.css文g攑օL目录

     3.?src/resource/extremetable.properties 复制到对应目?/p>

0.3 使用Compact View很重?/h3>

     默认的式样不W合大家的审，q怺q有Compact View和css讄Q让我们可以敬谢不敏它号U非常方便的HtmlView子类扩展?/p>

    1. 在全局讄?/p> 

 
table.view.html=org.extremecomponents.table.view.CompactView

    2.把images?table/compact/*.gif copy ?/table

2.全局属性配|?/h2>

   ExtremeTable支持在properties文g里方便的l一配置丰富的全局属?/p>

  ?source/org/extremecomponents/table/core目录扑ֈextremetable.properties文g,把它复制到WEB-INF/classes里面.

 在web.xml里面增加

   <context-param>
        <param-name>extremecomponentsPreferencesLocation</param-name>
        <param-value>/extremetable.properties</param-value>
   </context-param>

一般只写需要修改的文g:

table.filterable=false
table.imagePath=/images/table/*.gif
table.locale=zh_CN
table.view.html=org.extremecomponents.table.view.CompactView
row.highlightRow=true
column.format.date=yyyy-MM-dd
column.format.currency=###,###,###,###,#00.00

3.导出Excel

    注意Excel 导出的Tag已改为，且官方版不支持中文文件名?/p> 

    <ec:exportXls fileName="BookList.xls" tooltip="导出 Excel"/>

在web.xml必须加入Q?/p> 

    <filter>
        <filter-name>eXtremeExport</filter-name>
        <filter-class>org.extremecomponents.table.filter.ExportFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>eXtremeExport</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

     ExtremeTable导出的一w要特性是可以Ҏ不同的View导出不同的列.

     比如html理界面可能只列单几个最重要的列Q而导出excel时则需要导出所有的列?/p> 

<ec:column property="orderdate" title="订单日期"  cell="date" format="yyyy-MM-dd"  viewsDenied= "html"/>

又比如有些操作按U的列只惛_html出现,excel里不惛_玎ͼ

<ec:column property="orderdate" title="订单日期" viewAllowed= "html"/>

     以上订单日期列在html view看不刎ͼ而excel,pdf view可以见到.

    ?~辑图标"Q?选择Checkbox"q些理界面上的列，也可以设|不export到pdf,excel view

4.其他要点

4.1. 使用排序功能?如果property为嵌套属性时,需要设|alias

          因ؓjavascript的关p?

<ec:column property="customer.name" title="客户名称" alias="customer"/>

4.2. Date Cell与NumberCell 和RowCountCell

     在全局属性定?

 column.format.date= yyyy-MM-dd
column.format.currency= K?##,###,#00.00
<ec:column property="totalprice" title="总金? cell="currency" width="80" />
<ec:column property="shipdate" title="发货日期"  cell="date" width= "80"/>
<e

其中RowCountCell用于昄序号?/p>

4.3. 汇?/h3>

在column中加入两个cac属性，׃自动在table的底端显C汇?/p> 

<ec:column property="totalprice" title="总金? cell="number" format="###,###,##0.00" calc="total" calcTitle= "汇?"/>

4.4 i18N

在Web.xml里面指定i18N的Properties文g

<context-param>
  <param-name>extremecomponentsMessagesLocation</param-name>
  <param-value>messages</param-value>
</context-param>
<ec:column property="name" title="book.name"/>

4.5数据库分?/h3>

 EC默认从数据库中查找所有记录然后由它来分页Q如果查询结果较大，可以考虑使用数据库端分页的方案?/p>

 此时QEC会用Limit对象向Controller传递PageNo,PageSize,OrderBy{分信息。而服务端向ECq回总记录数和当前页的内容，具体请参?BookController?/p>

4.6不显C导出excel及分?/h3>

最快的方式是设|table的showStatusBar= false

<ec:table  items= "order.orderItems"var="item" action=""   showStatusBar= "false">

    4.7ImagePath

  旧版EC包括其文档都在每个table tag里定义ImagePath, 新版已经可以自动插入ContextPath,只需在properties文g定义table.imagePath=/images/table/*.gif卛_

5.自定义及扩展

   ExtremeTable比Display Tag的i一个就是良好的自定义和扩展能力Q不用千Z面?br />   不过QhL懒的Q虽然扩展子cdҎQ但能不扩展p是不可扩展了。幸亏用Compact View再改改CSS一般就能达到要求?/p>

 5.1. 良好的CSS定义

         ExtremeTable 的CSS定义非常严}, q且提供很多个层ơ的修改方式:

         1.直接修改css文g, 可以把table viewҎL样式

         2.修改全局属? 改变某种元素对应的css class?/p> 

table.styleClass=tableRegion

         3.在某个页面的row,column tag中定义class

 <ec:row style="" or styleClass=""/>

        SpringSide采用层次1, 直接修改extremecomponents.css为合适的样式

5.2方便?lt;tr><td>属性扩?/h3>

        row与column已提供了丰富的普通属性与 javascript属性如onClick(), 如果属性仍然未?可自行扩?lt;row>?lt;column>tag Qƈ通过全局属性指定新的子cd?/p>

   Z方便大家在子cL展属? extreme Table提供了专门的回调函数与Util函数?/p> 

public void addColumnAttributes(Column column) {
   column.addAttribute("customAttributeOne", customAttributeOne);
}

详细L手册,Table, Row,Column都提供相同的扩展:
http://extremecomponents.org/wiki/index.php/Column#Extended_Attributes

如果不是Extremetable的特别支? 普通taglib class要扩展属性的?
        1.定义真正的Java属?setter,getter
        2. tld文g中声明新的属?
        3.重蝲输出函数新属性打印出?/p>

5.3 扩展HTMLView,cell {显C组?/h3>

     Extreme Table在这些类的扩展上放便很多Q但q个版本里我q没有进行尝试，׃写了。请自行参考官Ҏ?http://extremecomponents.org/wiki/index.php/Html_View_Tutorial .

       l构设计前后兼容性不是很好，不同版本的jfreechart中类库结构可能不一P有时候可能需要查源码。如?br />       是中文显C的时候可能依据观感需要改变源码的字体Q不q我个h觉得q个版本比以前版本要好一些?br />
三、JFreeChart功能介绍
    JFreeChart目前是最好的java囑Ş解决ҎQ基本能够解决目前的囑Ş斚w的需求，主要包括如下几个斚wQ?br />    pie charts (2D and 3D)Q饼图（q面和立体）
    bar charts (regular and stacked, with an optional 3D effect)Q柱状图
    line and area chartsQ曲U图
    scatter plots and bubble charts
    time series, high/low/open/close charts and candle stick chartsQ时序图
    combination chartsQ复合图
    Pareto charts
    Gantt chartsQ甘特图
    wind plots, meter charts and symbol charts
    wafer map charts
    (态图?饼图(二维和三l? , q图?水^,垂直),U图,点图,旉变化?甘特? 股票行情?混和? 温度计图, d囄常用商用图表)
    囑Ş可以导出成PNG和JPEG格式Q同时还可以与PDF和EXCEL兌
    
    JFreeChart核心cd介绍Q?br />            研究jfreechart源码发现源码的主要由两个大的包组成：org.jfree.chart,org.jfree.data。其中前者主要与囑Ş
    本n有关Q后者与囑Ş昄的数据有兟뀂具体研I如果大家有兴趣的话可以自己研究Q以后有旉我会告诉大家怎么?br />    研究源码?br />         核心cM要有Q?br />           org.jfree.chart.JFreeChartQ图表对象，Mcd的图表的最l表现Ş式都是在该对象进行一些属性的定制。JFreeChart引擎本n提供了一个工厂类用于创徏不同cd的图表对?br />           org.jfree.data.category.XXXDataSet:数据集对象，用于提供昄图表所用的数据。根据不同类型的图表对应着很多cd的数据集对象c?br />           org.jfree.chart.plot.XXXPlotQ图表区域对象，基本上这个对象决定着什么样式的图表Q创对象的时候需要Axis、Renderer以及数据集对象的支持
           org.jfree.chart.axis.XXXAxisQ用于处理图表的两个_Uu和横?br />           org.jfree.chart.render.XXXRenderQ负责如何显CZ个图表对?br />           org.jfree.chart.urls.XXXURLGenerator:用于生成Web图表中每个项目的鼠标点击链接

创徏一个数据源QdatasetQ来包含要在图形中昄的数?br />创徏一?JFreeChart 对象来代表要昄的图?br />把图形输?br />重要的类和接口：
org.jfree.data.general.Dataset 所有数据源c都要实现的接口
org.jfree.chart.ChartFactory 由它来?JFreeChart 对象
org.jfree.chart.JFreeChart 所有对囑Ş的调整都是通过它噢Q！
org.jfree.chart.plot.Plot 通过JFreeChart 对象获得它，然后再通过它对囑Ş外部部分Q例Q坐标uQ调?br />注意Q它有很多子c，一般都下嗍造型到它的子c！
org.jfree.chart.renderer.AbstractRenderer 通过JFreeChart 对象获得它，然后再通过它对囑Ş内部部分
Q例Q折U的cdQ调整。同P针对不同cd的报表图Q它?br />着不同的子cd玎ͼ在下面我们简U它?Renderer
下面我们l合不同cd的图形来具体分析q个程?br />

q里只是一些常用的ҎQ具体还是看API
十、Item Lable
q里以柱状图Z说明Q具体来说就是在每个q上显C它的数据，具体有下面内容：
A、 Item Lable 可见
B、调?Item Lable 的颜艌Ӏ字体等
C、调?Item Lable 的位|?br />D、定?Item Lable 的内?br />1、分配一?Lable Generator l?renderer
BarRenderer barrenderer = (BarRenderer)categoryplot.getRenderer();
GategoryLableGenerator generator =new StandardGategoryLableGenerator(
“{2}? new DecimalFormat(?.00? //调整昄的数字和字符格式
);
barrenderer.setLableGenerator(generator);
2、 Item Lable 可见
barrenderer.setItemLableVisible(true);
3、调?Item Lable 的颜艌Ӏ字体等
barrenderer.setItemLablePaint(Color.red);
barrenderer.setItemLableFont(new Font(”SansSerif?Font.PLAIN,10));
4、调?Item Lable 的位|?br />q里涉及C个新的对?ItemLablePosition , ItemLablePosition的构造函数有两个或四个参?br />public ItemLabelPosition(ItemLabelAnchor itemLabelAnchor,
org.jfree.ui.TextAnchor textAnchor,
org.jfree.ui.TextAnchor rotationAnchor,
double angle)
itemLabelAnchor - Item Lable 的位|?Q最重要的！Q）
textAnchor - Item Lable里包含的正文相对于Item Lable 的位|?br />rotationAnchor - Item Lable里包含的正文旋{的位|?br />angle - 旋{的角?br />ItemLabelPosition itemlabelposition = new ItemLabelPosition(ItemLabelAnchor.INSIDE12,
TextAnchor.CENTER_RIGHT,
TextAnchor.CENTER_RIGHT,
-1.57D);
barrenderer.setPositiveItemLabelPosition(itemlabelposition);
q样可以每个柱状上昄它的数据了，当然可以定制 Item Lable 的内容，比如 Item Lable text 过100的才昄Q这样就需要定制自qc，它要实现GategoryLableGenerator 接口Q实现generateItemLable()Ҏ


其他说明Q?br />//讄Legend的位|?br />        //((JFreeChart) chart).getLegend().setPosition(RectangleEdge.RIGHT);
//讄最高的一?Item 与图片顶端的距离

        plot.getRangeAxis().setLowerMargin(0.15);
        //坐标轴字?br />        plot.getDomainAxis().setLabelFont(new Font("宋体", Font.PLAIN, 12));
        //横u每个分类的字?br />        plot.getDomainAxis().setTickLabelFont(new Font("宋体", Font.BOLD, 12));
        if(labelPositionsUP_45)
            plot.getDomainAxis().setCategoryLabelPositions(CategoryLabelPositions.UP_45);

Pager-taglibQ支持多U风格的分页昄。实际上Ҏ一个Jsp标签库，为在JSP上显C分信息而设计的一套标{，通过q些标签的不同的l合Q会形成多种不一L分页面Q风格各异，她自带的DEMO有七种左右的分风|包括Google的分风根{而需要订制自已的风格的分页面也非常单?
分页方式有两U：
一U是从Action中得C个ListQ在面上通过<pg:item>q行自动分页?
W二U是通过?pageSize,pageNo两参Cl后台进行数据库分页?

我做两个Demo加以说明ҎQ?/p>

二、准?/b>
把pager-taglib.jar攑ֈlib目录?仅此亦Q完全没必要改web.xml什么的Q还有官方war包中的东襉K可以不要)

代码
<%@ taglib uri="http://jsptags.com/tags/navigation/pager" prefix="pg" %>

三，jsp Q第一U分|案由<pg:item>自行分页 Q?/p>

代码
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@tagliburi="/WEB-INF/tld/c.tld"prefix="c"%>
<%@ taglib uri="http://jsptags.com/tags/navigation/pager" prefix="pg" %>

     </tr>
</pg:item>

</c:forEach>
</table>

      <% if (pageUrl != null) { %>

  </pg:index>
</pg:pager>

</body></html>

四．标签讲解Q从面里可以看刎ͼq里使用了几个标{?/b>

1?lt;pg:pager>,在这个标{ֺ里就充当着一个领袖的作用Q一切子标签都在它里面工作。就以上出现的参数进行解释一下：
itemsQ数据的U录?
maxPageItemsQ显C最多的U录??
maxIndexPagesQ显C最多的分页?ơ，如设?的话Q则会出现这L情况 1 2 3 4 5 .?3 4 5 6 7 q样的Ş式，其实她自带的DEMO都喜Ƣ把|展现出来排成一排?
isOffsetQ与pg:item配套使用
exportQ这个属性比较重要，文档也对此作好相寚w幅的说明。这个属性是让标{你暴露什么变量，当然q些变量是有选择的，如在Pager标签里，可以暴露出来的变量有pageOffset及pageNumberQ即늠偏移量及늠。通过q两个变量名Q可以在Jsp或Java里面从Request里获得。Export属性接受的D有表辑ּQ如currentPage=pageNumber表示Q把pageNumber的值暴露出来，q赋l一个叫CurrentPage的变量，q个变量被保存到Request中，在Jsp或Java中可以得到?
scopeQ咳。还需要讲么？

2?lt;pg:param>q个标签很有用，用来讄要加入到URL的参数。用Name属性指定即可。在q个Demo中我们还没有用的参数传递，下一个Demo你会看到它的用法?/p>

3?lt;pg:index>q个标签说明分页条显C的内容Q在q里你可以设|各U风格的分页昄方式Q本例是google风格的分|?
4, <pg:prev> , <pg:pages>,<pg:next>q些标签都是D标签֐思义,你一看例子就明白了，我就不用讲了吧?/p>

五，W二U分|?
与页面自行分不同的是还需要给后台传两个参敎ͼ
一个是pageNoQ当前页敎ͼ
可以在每一个PageUrl后面都加?amp;pageNo=<%= pageNumber %>。让我们的URL带上늠的参敎ͼq样E序可以拿到늠L找所需要的数据Q你可以L较一下两Demo的代码。OKQ另一个参数是pagesize,q个原本可以在url=?PageAction.do?pagesize=5来做可是Q?lt;pg>标签不支持这样做它给我们提供了另一个传递变量的ҎQ对了就是我前面标签讲解中所提到q的?lt;pg:param>

代码
<pg:pageritems="${totalRows} "url="/PageAction.do?pagesize=5"

q样传递参C对，应该写成Q?
代码
<pg:pageritems="${totalRows}"url="/PageAction.do"maxIndexPages="5">
<pg:paramname=" pagesize "value="5"/>
另外׃不需要在面分页所?lt;pg:param>要去?
再就?lt;pg:pager>要有items属?

六．以下是Demo代码

代码
<pg:pager
items="${ totalRows }"
url="/PageAction.do"
index="half-full"
maxPageItems="5"
maxIndexPages="10"isOffset="<%=false%>"
export="pageOffset,currentPageNumber=pageNumber"
scope="request">
<pg:paramname="pagesize"value="5"/>

<tablealign="center">
<c:forEachitems="${userlist}"var="user">

<tdheight="39">${user.userId}</td>

      <td height="39">${user.username}</td>
<tdheight="39">${user.password}</td>

     </tr>
<!--/pg:item-->

</c:forEach>
</table> 

 <pg:index>

    <center>

    <table border=0 cellpadding=0 width=10% cellspacing=0>

    <tr align=center valign=top>

    <td valign=bottom><font face=arial,sans-serif
