重分组介绍
语法：<?for-each-group: BASE-GROUP;GROUPING-ELEMENT?>
用法：重分组可以把XML数据做重新分组，这样数据的展示就不一定必须按照XML数据的结构显示。例如原来的XML数据结构是CD类别->CD信息（名称，年份，国家，价格），我们可以用重分组功能按CD年份->CD国家来显示.
重分组应用
1 按照和XML数据不同的结构显示数据
XML数据格式如下：
<CATALOG>
<TITLE>Empire Burlesque</TITLE>
<ARTIST>Bob Dylan</ARTIST>
<COUNTRY>USA</COUNTRY>
<COMPANY>Columbia</COMPANY>
<PRICE>10.90</PRICE>
<YEAR>1985</YEAR>
。。。。。
</CATALOG>
报表打算按照国家和年份重新分组，用到的重分组如下：
<?for-each-group:CD;COUNTRY?>
<?for-each:current-group();YEAR?>
这里的current-group()表示当前COUNTRY组下的子分组
2 显示PIVOT报表
XML数据如下：
<ROWSET>
<RESULTS>
<INDUSTRY>Motor Vehicle Dealers</INDUSTRY>
<YEAR>2005</YEAR>
<QUARTER>Q1</QUARTER>
<SALES>1000</SALES>
</RESULTS>
<RESULTS>
<INDUSTRY>Motor Vehicle Dealers</INDUSTRY>
<YEAR>2005</YEAR>
<QUARTER>Q2</QUARTER>
<SALES>2000</SALES>
</RESULTS>
<RESULTS>
<INDUSTRY>Motor Vehicle Dealers</INDUSTRY>
<YEAR>2004</YEAR>
<QUARTER>Q1</QUARTER>
<SALES>3000</SALES>
</RESULTS>
</ROWSET>
如果想按年份生成PIVOT表，可以用如下TAG实现：
<?for-each-group@column:RESULTS;YEAR?>
<?YEAR?>
<?end for-each-group?>
<?for-each-group:RESULTS;INDUSTRY?>
<?for-each-group@cell:current-group();YEAR?>
<?sum(current-group()//SALES)?>
<?end for-each-group?>
<?end for-each-group?>
这里的@cell是给每个组生成一个CELL

RTFTemplate巧妙的利用了word的“域”和书签实现了报表模板的设计。通过向rtf插入特定类型的域字段，用来标记将会被报表引擎用实际数据或者逻辑替代的部分。
通常单一的值用：Mergefield代替。
循环和条件采用：bookmark替代。
RefTemplate底层采用了两类模板引擎：
第一类：Jakarta Velocity
第二类：freemark
采用的模板不同生成的中
