1、显示循环时，可以使用{{#片断名}}。
模板字典类似Key和Value的结构，对应的是变量名和值。
片断是可以有多条记录的，如果要显示列表，可以定义为片断，获取多条记录填充到字典中。
片断可以显示，也可以不显示。如果片断的字典有数据，显示。如果片断的字典没有数据，默认是不显示的，可以调用ShowSection来显示。
2、一个结合了片断名，包含模板的示例
模板1
ctexample.tpl
<html>
<head>
<title> {{NAME}} </title>
</head>
{{!This is a example of template.}}
<body>
Hello {{NAME}},
You have just won ${{VALUE}}!
<table>
{{#IN_TABLE}}
<tr>
<td> {{ITEM}} </td>
<td> {{TAXED_VALUE}} </td>
</tr>
{{/IN_TABLE}}
</table>
{{>INCLUDED_TEMPLATE}}
</body>
</html>
<!--ctinclude.tpl-->
<div>
{{INCLUDE_VAR}}
</div>
模板2
example.tpl
Hello{{NAME}},
You have just won ${{VALUE}}!
{{#IN_CA}}
Well, ${{TAXED_VALUE}}, after taxes.
{{/IN_CA}}

return 0;
