将节标题下划线延伸至边距

将节标题下划线延伸至边距

我使用 Koma 字体，并将章节标题编号设置在页面边缘。我还为章节标题添加了彩色下划线。如果可能的话，我希望章节标题的下划线能够延伸到包含编号的位置，即延伸到足以从章节编号本身开始的位置开始的边缘。

作为奖励，目前我的章节编号出现在页边距的不同距离处 - 它们在页边距中刚好足以容纳该编号。我更愿意将它们设置在页边距左侧的固定量处，以便每个编号的左侧对齐。

下面一次性绘制了编号和标题下的线条。我们将编号放在一个固定宽度的框中，由新的长度控制\mysecnumhang。然后我们定义部分线条格式以 (1) 备份此宽度，(2) 打印带有部分编号和标题的框，以及 (3) 为所有内容添加下划线。

这不是一个真正干净的解决方案，但您可以在左侧重叠的部分编号下绘制零宽度规则，这些规则会融入实际下划线中。请注意，规则的框是零宽度（使用\makebox[0pt]），而规则本身具有命令中指定的宽度\rule- LaTeX 只是忽略宽度来计算以下内容的位置。
