DITA-OT 3.7.4中com.elovirta.ooxml v.1.4.0合并单元格处理异常

使用DITA-OT 3.7.4版本搭配com.elovirta.ooxml v.1.4.0插件，将包含合并单元格的HTML表格转换为DOCX格式后，合并格式无法正确保留，预期转换后的表格结构应与原HTML表格完全一致。

转换示例：原HTML表格的合并单元格布局在DOCX输出中未被正确还原，合并效果丢失。

Ditamap示例 #

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE map PUBLIC "-//OASIS//DTD DITA Map//EN" "lw-map.dtd">
<map>
    <title>merged cells problem</title>
    <topicref href="hdita/example.html" format="hdita"></topicref>
</map>
