我的ftl模版如下：
[align=left] <#list table1 as plan4>
<w:tr w:rsidR="00430067" w:rsidTr="00430067">
<w:tc>
<w:tcPr>
<w:tcW w:w="4261" w:type="dxa"/>
</w:tcPr>
<w:p w:rsidR="00430067" w:rsidRDefault="00430067">
<w:r>
<w:rPr>
<w:rFonts w:hint="eastAsia"/>
</w:rPr>
<w:t>${plan4.XueHao}</w:t>
</w:r>
</w:p>
</w:tc>
<w:tc>
<w:tcPr>
<w:tcW w:w="4261" w:type="dxa"/>
</w:tcPr>
<w:p w:rsidR="00430067" w:rsidRDefault="00430067">
<w:r>
<w:rPr>
<w:rFonts w:hint="eastAsia"/>
</w:rPr>
<w:t>${plan4.Name}</w:t>
</w:r>
<w:bookmarkStart w:id="0" w:name="_GoBack"/>
<w:bookmarkEnd w:id="0"/>
</w:p>
</w:tc>
</w:tr>
</#list>[/align] [align=right][align=left] --------------------编程问答-------------------- 先判断下是否为空再使用
<#if plan4.XueHao ? exists>
${plan4.XueHao}
</#if> --------------------编程问答-------------------- 回复1#.但这样我也试了，这样往那个表里就写不进去内容了。怎么办？ --------------------编程问答-------------------- 回复一楼，如果为空该怎办？如果不为空又该怎么办啊？求解。谢谢诶您
补充：Java , Web 开发
