How to lnsert Centered Vertical Dots in a Table with Multiply lmages to Express Omit

Question

I have a question about vertical dots, generally, I'm now using \vdot in a table to express omit, but I want them to be centralized to express omit, the current codes are shown below:

\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}

I had tried to use \usepackage{mathtools} but it seems not to work, is there anyone familiar with this? Thanks in advance!

Please make a compilable [mre], including the necessary packages and a documentclass — samcarter_is_at_topanswers.xyz, Nov 29 '21 at 16:55
if you want to use a math command, you need to make sure that you are in math mode and not in a normal left aligned column — samcarter_is_at_topanswers.xyz, Nov 29 '21 at 16:57
Also why on earth do you put your images in math mode in a siunitx column???? — samcarter_is_at_topanswers.xyz, Nov 29 '21 at 16:58
and please count your columns. You specify 4. but then only give 3 columns — samcarter_is_at_topanswers.xyz, Nov 29 '21 at 16:59
@samcarter_is_at_topanswers.xyz Sorry about the late reply, I had modified it but I'm not sure whether all is correct, I just learn LaTex for several days and has no conception of siunitx column, this table is actually modified based on many people's help and I still cannot understand all clearly, I will always working on this recently. — Tim, Nov 29 '21 at 19:20

A couple of problems:

the siunitx package is missing
the number of columns specified and actually in the table does not match
the S column is missing instructions how to align the numbers
to centre your vdots while the rest of the column is justified, you can use the \makecell macro from the package of the same name
images are not math, don't put them in math mode

\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}}
\usepackage{siunitx}
\usepackage{makecell}
\begin{document}
\begin{table}[htbp]
    \caption{Text.}
    \begin{tabularx}{\textwidth}{ @{} S[table-format=4.0] c X @{} }
    \toprule
        {Iterations} & Samples & Comments \
    \midrule
        0     & \includegraphics[width=.6\textwidth,valign=M]{example-image-duck} & Text is always being here\
        32    & \includegraphics[width=.6\textwidth,valign=M]{example-image-duck} & Text \ 
        {$\vdots$} & $\vdots$ & \makecell[c]{$\vdots$} \
        3200  & \includegraphics[width=.6\textwidth,valign=M]{example-image-duck} & Text \
    \bottomrule
    \end{tabularx}
    \label{tab4}
\end{table}
\end{document}

Thanks for your fast and detailed reply! I only have one more question, why should we comment \usepackage{cellspace}, because if this, the gap between different rows is missing...... — Tim, Nov 29 '21 at 20:09
And is there any way to also left-align the "Samples"? If possible. — Tim, Nov 29 '21 at 20:18
use an l column to left align them, but all your images have the same width, so it should not matter. — samcarter_is_at_topanswers.xyz, Nov 29 '21 at 20:34
