本文介绍 eXtremeTable 的最新更新，包括 RowTag 和 ColumnTag 的新功能、AutoGenerateColumns 的改进、TableTag 的 collection 属性变更等。此外还介绍了 BaseModel 重命名为 TableModel、Limit 和 LimitFactory 的接口化、以及多种 Tag 属性的详细说明。
15.1.3. RowTagRowTag<ec:row> 现在被需要，它被用来替代columns。 现在看来它一直被需要。它不知道表中到底有多少列，最近重构的时候我通过 Table -> Row -> Column使结构固定来合并得到更好的灵活性。将来我可能提供更多的 特性，因为我知道eXtremeTable有着清晰的架构。
典型的eXtremeTable如下：
<ec:table items="presidents" var="pres" action="${pageContext.request.contextPath}/presidents.run" > <ec:row> <ec:column property="name"/> <ec:column property="term"/> </ec:row></ec:table>
15.1.4. AutoGenerateColumnsAutoGenerateColumns得到了很大的提高，现在你只需要设置你需要的属性。 当你添加列到ColumnHandler使，defaults将别自动调用。
AutoGenerateColumns为singleton并且不是线程安全的，因此不要定义任何类变量。
现在它的实现可能如下：
public class AutoGenerateColumnsImpl implements AutoGenerateColumns { public void addColumns(TableModel model) { Iterator iterator = columnsToAdd().iterator(); while (iterator.hasNext()) { Map columnToAdd = (Map) iterator.next(); Column column = new Column(model); column.setProperty((String) columnToAdd.get(PROPERTY)); column.setCell((String) columnToAdd.get(CELL)); model.getColumnHandler().addAutoGenerateColumn(column); } }}
15.1.5. Extended AttributesaddExtendedAttributes方法重命名使得如何使用这个特性更清晰。 因此RowTag的addExtendedAttributes现在变为addRowAttributes，ColumnTag变 为addColumnAttributes，TableTag变为addTableAttributes，ExportTag变 为addExportAttributes。另外你参考正确的model bean（它的实现更清晰）， 将知道如何添加属性到你的cell、view.....
使用ExportCsvTag的示例如下：
public void addExportAttributes(Export export) { String view = export.getView(); if (StringUtils.isBlank(view)) { export.setView(TableConstants.CSV); export.setImageName(TableConstants.CSV); } export.addAttribute(CsvView.DELIMITER, getDelimiter());}
为了得到delimiter属性值你只需要从Export bean中get它：
Export export = model.getExportHandler().getCurrentExport();String delimiter = export.getAttributeAsString(DELIMITER);
现在你需要在ExportTag中覆盖它，你只需要调用setter方法。如果是新的属性，那么使用 可以和前一版一样使用addAttribute()方法。为了得到值，首先从ExportHandler得到Export， 然后调用需要的getter方法。这和使用其它tags一样。
在RowTag和ColumnTag中增加了两个新的callback方法：modifyRowAttributes和 modifyColumnAttributes，因此你可以在rows/columns被处理时改变属性值。
15.1.6. TableTag的collection属性TableTag的collection属性被删除，现在变为三个新属性：tableId、items和var。 因为我按照标准的JSTL命名，你应该能够根据这些名称知道他们的作用。tableId属性 被用来作为表的唯一标识，items属性用来表示从各种servlet的scopes里取得的集合， var属性表示你将使用EL编写脚本的名称。
依赖你的需要来决定如何使用新的属性，tableId用来唯一标识表。如果你的页面上只使用了 一个eXtremeTable并且不使用Limit特性，那么你根本不需要定义它。默认的表示名为'ec'；如果使用 Limit特性你也可以使用'ec'这个名称。然而，如果的一个JSP页面上同时使用两个eXtremeTables你就 需要使用tableId来唯一标识他们。var属性被用来你将使用EL编写脚本的名称。items属性用来表示从 各种servlet的scopes里取得的集合，而且现在非常健壮。你现在能nest集合到另外的对象，或者nest你想的 深度。
取得集合的语法如下：
<ec:table items="command.myObject.myCol" />
本示例将从命令对象（command object）取得myCol集合。
<ec:table items="myCol" />
本示例中将根据名称自动取得集合，就像以前版本的collection属性一样。
15.1.7. BaseModelBaseModel被重命名为TableModel，这是因为已经不需要一个基础包（base package）了，这也 意味着不再需要BaseModel了。
15.1.8. Properties和ResourceBundleweb.xml文件中使用extremecomponentsPreferencesLocation属性取代extremecomponentsPropertiesLocation属性， properties现在被Preferences接口控制。在以后的版本，我将提供可选的xml文件配置。
eXtremeTable不再默认在顶层类路径（top level classpath）寻找 extremecomponents.properties文件。你应该在web.xml中使用设置context-param属性的 值为extremecomponentsPreferencesLocation，这将更为通用。
web.xml文件中使用extremecomponentsMessagesLocation属性取代extremecomponentsResourceBundleLocation属性， internationalization现在被Messages接口控制。
Properties和ResourceBundle属性根据table、row、column、export和filterare区分开。 在以前版本中每个属性都以'table'开头，现在每个属性关联到被使用的标签。另外poperty不再需要使用奇怪的下划线语法， 而是使用dot来强调。
下面为properties文件的示例：
table.imagePath=/extremesite/images/*.giftable.rowsDisplayed=12column.parse.date=yyyy-MM-ddcolumn.format.date=MM/dd/yyyycolumn.format.currency=$###,###,##0.00
[英文的属性文件示例如下：]
statusbar.resultsFound={0} results found, displaying {1} to {2}statusbar.noResultsFound=There were no results found.toolbar.firstPageTooltip=First Pagetoolbar.lastPageTooltip=Last Pagetoolbar.prevPageTooltip=Previous Pagetoolbar.nextPageTooltip=Next Pagetoolbar.filterTooltip=Filtertoolbar.clearTooltip=Cleartoolbar.clearText=Cleartoolbar.firstPageText=Firsttoolbar.lastPageText=Lasttoolbar.nextPageText=Nexttoolbar.prevPageText=Prevtoolbar.filterText=Filtercolumn.headercell.sortTooltip=Sort Bycolumn.calc.total=Totalcolumn.calc.average=Average
15.1.9. pageContextTableModel （以前的BaseModel）不再直接访问pageContext，取而代之的是使用Context接口， 默认的被pageContext支持。直接访问pageContext是一个不好的实现，Context提供你需要从不同servlet scopes中 取得需要属性值的所有方法。然而，如果你需要直接访问背后的对象，可以使用getContextObject()方法。
15.1.10. Limit和LimitFactoryLimit和LimitFactory现在都是接口，以前版本的实现不如我想象的简单。然而， Limit对象的方法命名和以前版本的一样，因此你以前的代码也能很好的工作。
我两个Limit实现重构为一个，但是仍有两个LimitFactory实现， 从coding的观点用户只要使用一个 实现，但是它必须兼容以前的版本。现在只有一个Limit实现我重命名为TableLimit。同时，因为Limit特性 依赖Context而不是request，我重命名工厂类（TableLimitFactory）来reflect它。
Limit在导出时正确地显示行信息，Limit具有一个isExported()方法。
使用Limit和LimitFactory的示例如下：
Context context = new HttpServletRequestContext(request);LimitFactory limitFactory = new TableLimitFactory(context, tableId);Limit limit = new TableLimit(limitFactory);
设置row属性，仅设置totalRows和默认的行显示：
limit.setRowAttributes(totalRows, DEFAULT_ROWS_DISPLAYED);
RequestLimitFactory具有另一个如果没有指定tableId将设置为ec的构造函数：
Context context = new HttpServletRequestContext(request);LimitFactory limitFactory = new TableLimitFactory(context);
15.1.11. TableTag的saveFilterSort属性saveFilterSort属性被state属性取代，state属性参照State接口并能插接不通的关于 如何保存表状态的实现。
State接口如下：
public interface State { public void saveParameters(TableModel model, Map parameters); public Map getParameters(TableModel model);}
表新增了两个属性：state和stateAttr。state属性使用预设的四种 状态（default、notifyToDefault、persist和notifyToPersist）之一， 你也可以插接自己的实现。default状态不维持任何状态；persist状态没有任何参数传入，将一直维持表的状态； notifyToDefault状态将一直维持表的状态直到你传入参数告诉它回到default状态；notifyToPersist状态 将一直维持当前状态直到你传入参数告诉它维持persisted状态。stateAttr为指定参数提供了一条途径，你 也可以使用属性文件在全局范围内指定它。为了向后兼容，默认参数一直为useSessionFilterSort。
如果你想state按照不同方式工作你只要实现State接口，然后使用TableTag的state属性来指定实现类的 全路径。
15.1.12. ColumnTag的showTotal属性列新增了两个属性：calc和calcTitle：
<ec:column property="data" calc="total" calcTitle="Total:" />
calc属性实现具有唯一方法的Calc接口：
public interface Calc { public Number getCalcResult(TableModel model, Column column);}
它传入model和column，并返回一个Number型的值。默认的实现为总计和平均值。
为了使用定制的Calc，只需要使用ColumnTag的calc属性来指定实现Calc接口的实现类的 全路径。
Calc为singleton并且不是线程安全的，因此不要定义任何类变量。
showTotal因为不再适用在新版中被删除，我也删除了表中的totalTitle。
15.1.13. Image名search图片名从search变为filter。
15.1.14. FormTag / InputTag DeprecatedFormTag和InputTag现在为deprecated。他们在新的html视图（view）中不再被使用。
15.1.15. RetrieveRowsCallbacks、FilterRowsCallback、SortRowsCallbackCallbacks为singleton并且不是线程安全的，因此不要定义任何类变量。
