好的，這是桌子上的另一個（也許我們應該做一個系列）。
因此，我們已經用大括號將表格很好地組合在一起（感謝對一個問題的一些很好的回答）先前的問題）。
點擊代碼連結。
新問題是關於在表和 tex 等上覆蓋註釋（可能使用 tikz）。
只是一些微弱的線條來幫助讀者追蹤相鄰表中的對應值。這對於比較和對比相似點和差異特別有用。
這裡有幾個簡單的例子，展示了在僅 tikz 的環境中畫線是多麼容易。
\documentclass{standalone}
\usepackage{tikz,xcolor}
\usetikzlibrary{positioning}
\begin{document}
\begin{tikzpicture}
\tikzstyle{block} = [draw, rectangle,
minimum height=2.5em, text centered,
text width=1.9em]
\node[block, ] (A) {$A$};
\node[block, below=+1.000cm of A] (B) {$B$};
\node[block, right=-0.015cm of A] (C) {$C$};
\node[block, right=-0.015cm of B] (D) {$D$};
\node[block, right=-0.015cm of C] (E) {$E$};
\node[block, right=-0.015cm of D] (F) {$F$};
\node[block, right=-0.015cm of E] (G) {$G$};
\node[block, right=-0.015cm of F] (H) {$H$};
\draw[-,dotted,thick, color={black!40!white}] (A) -- (B);
\draw[-,dotted,thick, color={black!40!white}] (C) -- (D);
\draw[-,dotted,thick, color={black!40!white}] (E) -- (F);
\draw[-,dotted,thick, color={black!40!white}] (G) -- (H);
\end{tikzpicture}
\begin{tikzpicture}
\tikzstyle{block} = [draw, rectangle,
minimum height=2.5em, text centered,
text width=1.9em]
\node[block, ] (A) {$A$};
\node[block, below=+1.000cm of A] (B) {$B$};
\node[block, right=-0.015cm of A] (C) {$C$};
\node[block, right=-0.015cm of B] (D) {$D$};
\node[block, right=-0.015cm of C] (E) {$E$};
\node[block, right=-0.015cm of D] (F) {$F$};
\node[block, right=-0.015cm of E] (G) {$G$};
\node[block, right=-0.015cm of F] (H) {$H$};
\draw[-,line width=+0.916cm,color={black!20!white}] (A) -- (B);
\draw[-,line width=+0.916cm,color={black!20!white}] (E) -- (F);
\end{tikzpicture}
\end{document}
或簡單地：
\documentclass{standalone}
\usepackage{tikz,xcolor}
\usetikzlibrary{positioning}
\begin{document}
\tikzstyle{block} = [draw, rectangle,
minimum height=2.5em, text centered,
text width=1.9em]
\begin{tikzpicture}
\node[block, ] (A) {$A$};
\node[block, below=1cm of A] (B) {$B$};
\draw[-,dotted,thick, color={black!40!white}] (A) -- (B);
\end{tikzpicture}
\begin{tikzpicture}
\node[block, ] (A) {$A$};
\node[block, below=1cm of A] (B) {$B$};
\draw[-,line width=0.916cm,color={black!40!white}] (A) -- (B);
\end{tikzpicture}
\end{document}
也許我應該從一開始就在 tikz 中完成表格，但無論如何，有時你已經準備好了表格，或者出於某種原因你可能只是想/需要以某種方式完成它。所以無論如何，問題在於將註釋覆蓋在頁面上已有的內容上 - 而不是之前或之後。
答案1
我想你被騙了。這我的答案是基於程式碼不可能來自大衛。它既不複雜，也沒有任何z的。為了修正這個問題，我添加了一些稍微複雜一些的\Z.
