使用freemark导出数据到Word(遍历List)

将word模板另存为xml文件，进而重命名为.ftl文件，就得到了freemark的模板，因为是一个列表显示，我们需要所以我们需要根据freemark的标签进行改写，找到word中的每一个表格的行进行改写，改写后的ftl的文件如下：

<#list userList as user>
    <w:tr><w:tblPrEx><w:tblBorders><w:top w:val="single" w:sz="4" wx:bdrwidth="10" w:space="0" w:color="auto"/><w:left w:val="single" w:sz="4" wx:bdrwidth="10" w:space="0" w:color="auto"/><w:bottom w:val="single" w:sz="4" wx:bdrwidth="10" w:space="0" w:color="auto"/><w:right w:val="single" w:sz="4" wx:bdrwidth="10" w:space="0" w:color="auto"/><w:insideH w:val="single" w:sz="4" wx:bdrwidth="10" w:space="0" w:color="auto"/><w:insideV w:val="single" w:sz="4" wx:bdrwidth="10" w:space="0" w:color="auto"/></w:tblBorders><w:tblCellMar><w:left w:w="108" w:type="dxa"/><w:right w:w="108" w:type="dxa"/></w:tblCellMar></w:tblPrEx><w:trPr/><w:tc><w:tcPr><w:tcW w:w="2130" w:type="dxa"/><w:shd w:val="clear" w:color="auto" w:fill="auto"/></w:tcPr><w:p><w:pPr><w:rPr><w:rFonts w:hint="fareast"/><w:vertAlign w:val="baseline"/><w:lang w:val="EN-US" w:fareast="ZH-CN"/></w:rPr></w:pPr><w:r><w:rPr><w:rFonts w:hint="fareast"/><w:vertAlign w:val="baseline"/><w:lang w:val="EN-US" w:fareast="ZH-CN"/></w:rPr>

注：生成的ftl格式的word源码需要二次修改
