\tabitem 在第一行后缩进项目符号

Question

正如我们所见，问题在于项目符号没有保持缩进。

MWE 如下所示

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{indentfirst}
\usepackage{caption}
\usepackage{subcaption}

\newcommand{\tabitem}{~~\llap{\textbullet}~~}

\begin{document}
\begin{table}
     \centering
\begin{tabular}{| p{7cm} | p{7cm} |}
    \hline
        \multicolumn{2}{|c|}{Bezier Curves} \\
    \hline
        \multicolumn{1}{|c|}{Properties} & \multicolumn{1}{c|}{Disadvantages} \\
    \hline
        \tabitem A\newline
        \tabitem B\newline
        \tabitem C\newline
        \tabitem D \newline & 
        \tabitem E\newline
        \tabitem F\newline
        \tabitem G\\
     \hline
\end{tabular}
\end{table}
\end{document}

Answer 1

更改命令\newcommand{\tabitem}{\textbullet~~}。

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{indentfirst}
\usepackage{caption}
\usepackage{subcaption}

\newcommand{\tabitem}{\textbullet~~}

\begin{document}
\begin{table}
     \centering
\begin{tabular}{| p{7cm} | p{7cm} |}
    \hline
        \multicolumn{2}{|c|}{Bezier Curves} \\
    \hline
        \multicolumn{1}{|c|}{Properties} & \multicolumn{1}{c|}{Disadvantages} \\
    \hline
        \tabitem A\newline
        \tabitem B\newline
        \tabitem C\newline
        \tabitem D  & 
        \tabitem E\newline
        \tabitem F\newline
        \tabitem G\\
     \hline
\end{tabular}
\end{table}
\end{document}

Answer 2

使用itemize表格内具有方便参数的环境更简单：

\documentclass[11pt]{article}

\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{indentfirst}
\usepackage{caption}
\usepackage{subcaption}
\usepackage{enumitem}

\begin{document}

\begin{table}[!htb]
     \centering%
     \setlist[itemize]{wide=0.35em, leftmargin = *, itemsep=-3pt, before=\vspace*{-\dimexpr\baselineskip+\partopsep}, after =\vspace*{\dimexpr-\baselineskip+\partopsep}}
\begin{tabular}{| p{7cm} | p{7cm} |}
    \hline
        \multicolumn{2}{|c|}{Bezier Curves} \\
    \hline
        \multicolumn{1}{|c|}{Properties} & \multicolumn{1}{c|}{Disadvantages} \\
    \hline
\begin{itemize}
        \item A
        \item B
        \item C
        \item D
\end{itemize}
&
\begin{itemize}
        \item E
        \item F
        \item G
\end{itemize}\\
     \hline
\end{tabular}
\end{table}

\end{document} 

Answer 3

这是对我上面的评论的回答的转化。

在我的评论的第一部分，我提供了链接 我的答案，可以轻松适用于您的情况：

\documentclass[a4paper]{article}
\usepackage{enumitem}           % for nice list
\newlist{tablist}{itemize}{1}% <-- defined new list
\setlist[tablist]{nosep,     % <-- new list setup
                 topsep     = 0pt       ,
                 partopsep  = 0pt       ,
                 leftmargin = *         ,
                 label      = $\bullet$ ,
                 before     = \vspace{-0.5\baselineskip},
                 after      = \vspace{-\baselineskip}
                 }
\begin{document}
    \begin{table}
        \renewcommand\arraystretch{1.3}
        \centering
\begin{tabular}{| p{7cm} | p{7cm} |}
\hline
    \multicolumn{2}{|c|}{Bezier Curves} \\
\hline
    \multicolumn{1}{|c|}{Properties} & \multicolumn{1}{c|}{Disadvantages} \\
\hline
    \begin{tablist}
        \item B
        \item C
        \item D
    \end{tablist}   &   \begin{tablist}
                            \item E
                            \item F
                            \item G
                        \end{tablist}   \\
\hline
\end{tabular}
    \end{table}
\end{document}

在评论的第二部分，我建议替换你的定义

 \newcommand{\tabitem}{~~\llap{\textbullet}~~}

（rlap{...}你的麻烦出在哪里）

 \newcommand{\tabitem}{\textbullet~~}

其结果与上述 MWE 相同。哪种建议更合适由您决定 :)
