带框的命名法和与 pardent 的对齐

Question

我想使用 nomencl 包生成命名法，该命名法应位于一个框架中，并且标题和符号列都与全局 parindent 值对齐。文档类必须是 elsarticle，结果应该由此类给出的值控制 - 因此如果有意义的话，我无法更改全局值。

无论如何，到目前为止，我发现可以使用 patchcmd 来实现符号列的对齐。不幸的是，我不知道如何对标题做同样的事情，也试图弄乱给出的帮助这里，但没有成功。

我附加了一个示例，其中的缩进和 fbox 分隔和标尺值都非常夸张，以使问题更加严重。

其中我尝试过手动用 hspace 命令移动 header，但效果并不好，如图所示。还是有间隙，这很大程度上取决于设置的 parindent 和 frame box 设置。

我期待您的建议。

亲切的问候
