How to force a table into a single column in IEEE template?

Question

I trying to fit a table into an appendix using IEEE template. The table I am trying to add is too wide for a column and needs to be fit. The table also has to be added to a column in the appendix of the document.

This question is very similar to the one found here https://stackoverflow.com/questions/33971693/latex-ieee-template-use-single-column-table-in-multicolumn-latex-content .

I have added the particular table that I have been trying to fit into the document below, followed by the complete package and attempt at adding a the table. I have been finding similar questions online but nothing seemed to work. Thanks for your help in advance.

    % Please add the following required packages to your document preamble:
% \usepackage{graphicx}
\begin{table}[]
\resizebox{\textwidth}{!}{%
\begin{tabular}{lll}
Simulation   & Description                                              & Language \\
Markov Chain:            & Simultaneous and ergodic simulations of Markov chains, to understand implementation.                                       & Python \\
Multiarm bandit problem: & In order to compare greedy epsilon at different hyper-parameters \textbackslash{}varepsilon and optimistic value approach. & Python \\
Tic-tac-toe: & Implemented in R, to illustrate learning from a data-set & R        \\
Tic-tac-toe: & Implemented in Python.                                   & Python   \\
Grid World:  & Implemented in R.                                        & R        \\
Grid world:  & Implemented in Python.                                   & Python   \\
AI gym:      & Discrete Cart-pole AI gym.                               & Python  
\end{tabular}%
}
\end{table}

Answer 2

The answer provided by @leandriis in the comments above is use \begin{table} \small \begin{tabularx}{\linewidth}{p{1.75cm}> {\raggedright\arraybackslash}Xl}

This translated to:

\begin{table} \small \begin{tabularx}{\linewidth}{p{1.75cm}>{\raggedright\arraybackslash}Xl}
Simulation   & Description                                              & Language \\
