Linear variability

    \item  Slope of regression ($\alpha$)
    \item Median variability ($m$)
        \end{itemize}
        & Calculates the variability of a feature's time-series, and studies how that variability progresses with time (increases [$\alpha>0$], decreases [$\alpha<0$] or maintains [$\alpha=0$]).
        \\
Non-linear variability
    &   \begin{itemize}
    \item Central tendency measurement (CTM)
        \end{itemize}
        & Computes the feature's time-series variability using difference plots. The higher the CTM, the lower the variability, and vice-versa.
        \\
P-wave amplitude dispersion
    &   \begin{itemize}
    \item Amplitude dispersion index (ADI)
        \end{itemize}
        & Quantitative indicator of P-wave morphology variability. The greater the ADI, the greater the variability, and vice-versa. Uses the P-waves' signal.
        \\
Heart rate variability
    &   \begin{itemize}
    \item \textoverline{RR}, SDRR, SDSD, RMSSD, NN20, pNN20, NN50, pNN50
    \item TP, VLF, LF, HF, pHF, pLF, LF/HF

        & Studies the variability of the RR series using metrics from time- and frequency- domain. Gives indications on the autonomic nervous system.                                            \\

上のページでテストした結果は次のようになります。

上記の MWE では、トピック外の変更をいくつか行い、（私の好みに応じて）表をより見やすくしました（tabularx表環境のの使用により、makecellセルの内容の上下の垂直方向のスペースが広がりました）。

補遺: どうやら、ドキュメントクラスにはmdpiハードコードされたitemizeリストがあり、パッケージを使用して上書きできますenumitem。また、itemizeテーブルでを使用すると、と\parsepが\itemsep削減されるようです。

アイテム間の垂直スペースを増やす 1 つの方法は、\\[1.5ex]各アイテムの末尾に追加することです。このソリューションを使用すると、enumetemパッケージは不要になります。したがって、テーブル内のリストは、上記の MWE のように記述するか、以下の MWE のように新しい列タイプを定義することができます。
