如何在表格中插入居中垂直点，并添加多幅图像以表达省略

Question

抱歉打扰大家了！我有一个关于竖点的问题，一般我现在都是用\vdot在表格中来表示省略，但是我想让它们集中起来表示省略，目前的代码如下：

\documentclass{article}

\usepackage{amssymb} % Add
\usepackage{bbding} % Add
\usepackage[export]{adjustbox}
\usepackage{array}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{graphicx}
\usepackage{cellspace}
\def\tabularxcolumn#1{m{#1}}

\begin{document}

\begin{table*}[htbp]
    \caption{Text.}
    \begin{tabularx}{\textwidth}{ l Sl X }
    \toprule
        Iterations & Samples & Comments \\
    \midrule
        0     & \includegraphics[width=.6\textwidth,valign=M]{000000.png} & Text is always being here\\
        32    & \includegraphics[width=.6\textwidth,valign=M]{000000.png} & Text \\ 
        64    & \includegraphics[width=.6\textwidth,valign=M]{000000.png} & Text \\
        128   & \includegraphics[width=.6\textwidth,valign=M]{000000.png} & Text \\
        192   & \includegraphics[width=.6\textwidth,valign=M]{000000.png} & Text \\
        \vdots & \vdots & \vdots \\
        3200  & \includegraphics[width=.6\textwidth,valign=M]{000000.png} & Text \\
    \bottomrule
    \end{tabularx}
    \label{tab4}
\end{table*}

\end{document}

请保持行与行之间的间隙，除九个点外，其余所有点左对齐。提前感谢大家！

改编

• 用于example-image​最小工作示例（MWE）
  • height=20mm仅为该示例图像添加选项
• 用于\multicolumn{1}{c}{\vdots}将单个单元格居中对齐（参见在表格环境中对齐特定单元格）
• 表格中的数字应该右对齐（更好的样式）

代码

\documentclass{article}

\usepackage{amssymb} % Add
\usepackage{bbding} % Add
\usepackage[export]{adjustbox}
\usepackage{array}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{graphicx}
\usepackage{cellspace}
\def\tabularxcolumn#1{m{#1}}

\begin{document}

\begin{table*}[htbp]
    \caption{Text.}
    \begin{tabularx}{\textwidth}{ r Sl X }
    \toprule
        Iterations & Samples & Comments \\
    \midrule
        0     & \includegraphics[width=.6\textwidth, height=20mm, valign=M]{example-image} & Text is always being here\\
        32    & \includegraphics[width=.6\textwidth, height=20mm, valign=M]{example-image} & Text \\ 
        64    & \includegraphics[width=.6\textwidth, height=20mm, valign=M]{example-image} & Text \\
        128   & \includegraphics[width=.6\textwidth, height=20mm, valign=M]{example-image} & Text \\
        192   & \includegraphics[width=.6\textwidth, height=20mm, valign=M]{example-image} & Text \\
        \vdots & \multicolumn{1}{c}{\vdots} & \multicolumn{1}{c}{\vdots} \\
        3200  & \includegraphics[width=.6\textwidth, height=20mm, valign=M]{example-image} & Text \\
    \bottomrule
    \end{tabularx}
    \label{tab4}
\end{table*}

\end{document}

结果
