表格内容完全对齐

Question

我需要完全证明表格内容，例如 RSCA、RR1、RR2 等值。有没有办法在表格中提供值充分合理水平方向不是左对齐例如我们提供的\begin{tabular}{|l|l|l|}左对齐内容。

代码如下所示：

\def\arraystretch{1.3}%
\begin{table}[h]
\centering
\caption{Values of Dispersion Constant ($R$)}
\begin{tabular}{|l|l|l|}
\hline
\multicolumn{1}{|c|}{\textbf{Algorithm}} & \multicolumn{2}{ c|}{{\boldmath\textbf{Dispersion Constant ($R$)}}}\\
\hline
& \multicolumn{1}{ c|}{\textbf{M=16}} & \multicolumn{1}{ c|}{\textbf{M=32}}\\ \hline 
SCA & R\textsubscript{SCA} = 123 & R\textsubscript{SCA} = 123 \\\hline
\justifying
MCMA & R\textsubscript{R} = 2.55 and R\textsubscript{I} = 2.55  & R\textsubscript{R} = 2.55 and R\textsubscript{I} = 2.55\\
\hline 
\multirow{2}*{DD-MCMA} & R\textsubscript{R1} = 0.75 and R\textsubscript{R2} = 2.55 & R\textsubscript{R1} = 0.75 and R\textsubscript{R2} = 2.55 \\
& R\textsubscript{I1} = 0.75 and R\textsubscript{I2} = 2.55 & R\textsubscript{I1} = 0.75 and R\textsubscript{I2} = 2.55 \\
\hline
\end{tabular}
\end{table}

我想让这部分代码看起来水平对齐

SCA & R\textsubscript{SCA} = 123 & R\textsubscript{SCA} = 123 \\\hline
\justifying
MCMA & R\textsubscript{R} = 2.55 and R\textsubscript{I} = 2.55  & 
R\textsubscript{R} = 2.55 and R\textsubscript{I} = 2.55\\
\hline 
\multirow{2}*{DD-MCMA} & R\textsubscript{R1} = 0.75 and R\textsubscript{R2} 
= 2.55 & R\textsubscript{R1} = 0.75 and R\textsubscript{R2} = 2.55 \\
& R\textsubscript{I1} = 0.75 and R\textsubscript{I2} = 2.55 & 
R\textsubscript{I1} = 0.75 and R\textsubscript{I2} = 2.55 \\
\hline

列类型的解释（后的代码tabular）：

1. 你>{...}可以告诉 LaTeX 做一些事情前<{...}用一些东西写单元格内容后；您需要array这些选项的包
2. 告诉S[table-format=1.2]LaTeX 您有 1 个整数和 2 个小数，需要在小数点处对齐（siunitx需要包）
3. 您@{something}可以插入something而不是列间空格（array包）
4. 您!{something}可以插入something而不是|（始终查看array包装）。

\documentclass{article}
\usepackage{array}
\renewcommand{\arraystretch}{1.3}
\usepackage{siunitx}
\usepackage{caption}
\usepackage{amsmath}

\begin{document}
    \begin{table}[h]
        \centering\footnotesize
        \caption{Values of Dispersion Constant ($R$)}
        \begin{tabular}{
                |l|
                >{$}l<{$}@{${}={}$}S[table-format=1.2]
                !{and}
                >{$}l<{$}@{${}={}$}S[table-format=1.2]|

            \hline 
            DD-MCMA & R_\text{{R1}} & 0.75 & R_{\text{R2}} & 2.55 & R_{\text{R1}} & 0.75 & R_{\text{R2}} & 2.55 \\

            \hline
        \end{tabular}

如果您想要 Word 对齐，请使用\hfill：
