我这里测试的样例是没有问题的，可以看看下面的例子：

例子代码：
0426.zip

仔细看看说明书，提到了的，label 后面要加上 % 来规避空格。

\title{The Dog}

\begin{document}

The dog or domestic dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf, and is characterized by an upturning tail. The dog is derived from an ancient, extinct wolf, and the modern wolf is the dog's nearest living relative. The dog was the first species to be domesticated, by hunter–gatherers over 15,000 years ago, before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.

The dog has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They perform many roles for humans, such as hunting, herding, pulling loads, protection, assisting police and the military, companionship, therapy, and aiding disabled people. Over the millennia, dogs became uniquely adapted to human behavior, and the human-canine bond has been a topic of frequent study. This influence on human society has given them the sobriquet of "man's best friend".

这样的排版方式是竖排了，不是限制文本宽度变成了换行了而已。简单一点自己 shortstack 单独设置行间距。如果不多的情况，临时解决。

看看这里：

看不懂问题是什么？看看入门资料:

直接来肯定不行的，需要找到书签。
看看这里：

代码是啥？没听懂是啥意思。

与其这样不如给版面画个背景呢，用margin的方式实现批注。

完整的代码在哪里？最好有个复现代码，方便给出答案！

代码不完整，我这里整体调整如下：

\documentclass{article}
\usepackage{pgf,tikz}
\usetikzlibrary{shapes}
\makeatletter
\pgfdeclareshape{document}{
\inheritsavedanchors[from=rectangle] % this is nearly a rectangle
\inheritanchorborder[from=rectangle]

\inheritanchor[from=rectangle]{east}

\makeatother
\begin{document}

\draw[dashed] (x) -- (y);
\end{tikzpicture}

\end{document}

没看懂问题是什么，看看这个代码：

 \documentclass{IEEEtran}

\usepackage{algorithm}
\usepackage{algorithmic}
\begin{document}

 \begin{algorithm}[H]
 \caption{Algorithm for ...}
 \begin{algorithmic}[1]
 \renewcommand{\algorithmicrequire}{\textbf{Input:}}
 \renewcommand{\algorithmicensure}{\textbf{Output:}}
 \REQUIRE in
 \ENSURE  out
 \\ \textit{Initialisation} :
  \STATE first statement
 \\ \textit{LOOP Process}
  \FOR {$i = l-2$ to $0$}
  \STATE statements..
  \IF {($i \ne 0$)}
  \STATE statement..
  \ENDIF
  \ENDFOR
 \RETURN $P$
 \end{algorithmic}
 \end{algorithm}

\end{document} 

什么信息都没有，就这样的问题，无法回答。

第二行明显少了一个单元格，加上就好了。

\begin{tabular}{|c|c|c|c|c|}
\hline
\multirow{2}*{姓名} & \multicolumn{3}{c|}{成绩} & \multirow{2}{*}{总分} \\ \cline{2-4}
&语文&数学&英语& \\ \hline
张三 &98 &100&92 & 290 \\ \hline
李四 &99 &91 &99 & 289 \\ \hline
\end{tabular}
\begin{question}

你的参数就没加 breakable :

\tcbset{%
 %enhanced,
 breakable,
    colback      = white,
    tikz         = {opacity=0.8,transparency group},
    colframe     = black,
    title filled = false,
    colbacktitle = white,
}%%

这样设置。
