我制作了以下自定义部分标题：
这里有相当多的东西是硬编码的（即需要我亲眼观察），这让我很紧张。
- 为什么两者的
vrules宽度不一样（它们都有厚度）？如果我改为，3pt这个问题就消失了，但我不知道为什么会发生这种情况。\titlespacing\section{6.8in}{0in}{0in}\titlespacing\section{6.0in}{0in}{0in} - 如何确保右对齐标题与页边距齐平？现在，可以使用值
6.67in(A4 纸宽度 - 左边距宽度 - 右边距宽度 = 8.27 - 0.8 - 0.8 = 6.67) 手动完成，但由于某种原因，右侧的空间看起来比左侧的大。 - 如何确保
vrule和文本之间的间距相似？现在，它是使用手动完成的\hspace，我确信它们是不一样的。
我真的很感谢所有的意见——手动做事让我非常焦躁。

在软件包 (\filleft, \filright和filcenter) 提供的对齐工具中使用相关工具更为有效。我借此机会稍微简化了您的代码 -color如果您要加载，则无需加载xcolor，而使用选项加载后者[table]将使您不必加载colortbl（在这种情况下，在之后加载tcolorbox，以避免选项冲突）。
