java - 如何用docx4j替换标题和表格中的变量？

Question

我正在尝试替换文档标题和表格中的变量，但我不知道如何继续。我设法替换了文档正文中的变量，但此方法(使用 ${})不适用于标题和表格。

要替换 header 中的变量，需要对相关 header 部分进行变量替换。在这里，您只需在主文档部分中执行此操作。

关于表，变量替换内容并非旨在重复行(例如，每个发票行项目一行)。换句话说，它不会插入行。因此，如果您没有更多代码，您的 Object[][] orderItems 将不会执行任何操作。

(相比之下，docx4j 的 XML 数据绑定(bind)确实可以使用 OpenDoPE od:repeat 来处理该问题)
