Question 1

我对答案进行了大幅修改。结果如下。代码中有一些注释可以提供帮助。

使用tikz.sty和eso-pic.sty您可以实现类似的功能，而无需手动拆分文本。这是一个概念验证，我稍后有机会时会添加它。不过，这可能是一个开始。

我修正了我在实施格式时遇到的一个问题。

Question 2

我认为这种格式的主要问题是你想要在装饰边界框内采用两列格式。

和多列的组合tcolorbox是可能的，但需要满足某些条件。可破坏元素tcolorbox可以在多列中使用，但框会应用于每一列。您也可以multicol在内部使用环境tcolorbox，但前提是框不可破坏。所以，我认为没有简单的解决方案。

但如果您不介意使用非自动解决方案，tcolorbox也可以使用。以下代码显示了基于magazine和raster库的部分非自动解决方案。

magazine库允许将文本拆分并存储在多个框中，以便以后使用。使用此工具，可以将文本拆分为“一列宽 x 固定高度”的片段。

\begin{tcolorbox}[blanker, 
width=.4\textwidth,      %<-------- column width
breakable,
break at=.93\textheight,       %<----- column height
height fixed for=first and middle,
watermark text=\arabic{tcbbreakpart},
reset box array,
store to box array,]
\lipsum[1-7]              %<---- Here is the text
\end{tcolorbox}

一旦获得了 fragment 中的所有文本，就可以手动将其组合成breakable可以像其他任何文本一样进行装饰的栅格tcolorbox。在这种情况下，盒装的 tcbitemize 环境可以完成这项工作。

\begin{tcboxeditemize}[
     blanker, raster columns=2, sharp corners, 
     halign=center, raster valign=top]   %<--- inner boxes format and distribution
     {breakable, colback=yellow!10, 
      fonttitle=\bfseries, 
      attach boxed title to top center={yshift*=-\tcboxedtitleheight/2},      
      title=Exercicies, 
      overlay={\draw [shorten >=4mm, shorten <=4mm] 
           (frame.north)--(frame.south);}}  %<--- Format for outer box
  %--- Raster contents ---%
  \tcbitem\consumeboxarray{1}   %<---- First column
  \tcbitem\consumeboxarray{2}   %<---- Second column
  \tcbitem\consumeboxarray{3}   % ...
  \tcbitem\consumeboxarray{4}
\end{tcboxeditemize}

不幸的是，我不知道如何foreach在 a 中使用 a tcbraster，所以我们必须手动\tcbitem\consumebnoxarray{...}在文本中插入尽可能多的行作为片段。

最终结果如下：

如果您知道有多少个片段，倒数第二个片段可能会更短，这样您就会得到更加平衡的最后一页，但这不在本解决方案的范围之内。

此外，代码中省略了练习的内部格式。此代码只是尝试展示一个可能的起点。

获取前一张图像的完整代码是：

break at=.93\textheight,
height fixed for=first and middle,

reset box array,
store to box array,]
\lipsum[1-7]
\end{tcolorbox}

\begin{tcboxeditemize}[blanker, raster columns=2, sharp corners, halign=center, raster valign=top]{breakable, colback=yellow!10, fonttitle=\bfseries, attach boxed title to top center={yshift*=-\tcboxedtitleheight/2},  title=Exercicies, overlay={\draw [shorten >=4mm, shorten <=4mm] (frame.north)--(frame.south);}}
