格式化輸出表單中的數(shù)據(jù)

Q：怎么樣格式化輸出表單中的數(shù)據(jù)

A: 你可以設(shè)置列的cell：

?

日期格式化： cell = " date " format = " yyyy-MM-dd "

數(shù)字格式化： cell="currency" format="###,###,##0.00"?

在web.xml中添加編碼過(guò)濾器配置：

?<filter>???

?<filter-name>Set Character Encoding</filter-name>

??? <filter-class>filters.SetCharacterEncodingFilter</filter-class>???

?<init-param>????

? <param-name>encoding</param-name>?????

<param-value>gb2312</param-value>?

?? </init-param>?

</filter>

? <filter-mapping>??

? <filter-name>Set Character Encoding</filter-name>

??? <url-pattern>/*</url-pattern>?

</filter-mapping>

?

<!--配置導(dǎo)出功能的過(guò)濾器-->

<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>?

在extComments中加入鏈接

Q：怎么樣加入鏈接

A: 你可以參考下例:

<ec:table
var="pres"
items="presidents"
action="${pageContext.request.contextPath}/compact.run"
imagePath="${pageContext.request.contextPath}/images/table/compact/*.gif"
view="compact"
title="Compact Toolbar View"
showTooltips="false"
>
<ec:exportPdf
fileName="output.pdf"
tooltip="Export PDF"
headerColor="black"
headerBackgroundColor="#b6c2da"
headerTitle="Presidents"
text="PDF"
/>
<ec:exportXls
fileName="output.xls"
tooltip="Export Excel"
text="XLS"
/>
<ec:row>
<ec:column property="fullName" title="Name">
<a href="http://www.whitehouse.gov/history/presidents/">${pres.fullName}</a>
</ec:column>
<ec:column property="nickName"/>
<ec:column property="term"/>
<ec:column property="born" cell="date"/>
<ec:column property="died" cell="date"/>
<ec:column property="career"/>
</ec:row>
</ec:table> Limit數(shù)據(jù)端分頁(yè)

創(chuàng)建Limit

首先你需要通過(guò)LimitFactory得到一個(gè)Limit實(shí)例：

Context context = new HttpServletRequestContext(request);
LimitFactory limitFactory = new TableLimitFactory(context, tableId);
Limit limit = new TableLimit(limitFactory);
