Vertical spacing in table

Question

I am trying to create a table, but inside has some mathematical fractions which is too wide for the table.

Originally I used arraystretch 1.4, the vertical space is too tight. So I wanted to stretch wider.

When I used 2.4, the problem is that it is not vertically aligned anymore.

The problem might not seem apparent in this, so when I increase further to 4, it is even less vertically aligned.

Can someone help me understand and find the correct solution? Thanks in advance.

PS: Incidentally, I use LuaLaTeX as the default compiler.

\documentclass[twoside,14pt]{extarticle}
\usepackage{array}
\newcolumntype{L}[1]{>{\raggedright\arraybackslash}m{#1}}

\usepackage{amsmath}

\begin{document}

    \renewcommand{\arraystretch}{2.4}
    \setlength\tabcolsep{1.5\tabcolsep}
    \setlength\arrayrulewidth{1.5pt}
    \begin{center}
        \begin{tabular}{!{\vrule width 1.5pt} L{75mm} !{\vrule width 1.5pt} L{75mm} !{\vrule width 1.5pt}}
            \hline
            As $\displaystyle f\left(x\right) \rightarrow +\infty$, & $\displaystyle \dfrac{1}{f\left(x\right)} \rightarrow$
            \\ \hline
        \end{tabular}
    \end{center}    

\end{document}

The cellspace ensures a minimal vertical padding of cells in columns with specifier prefixed with the letter S (or C if you load siunitx). This works better with the pcolumn type, for some reason:

\documentclass[twoside,14pt]{extarticle}

\usepackage{array}
\usepackage{cellspace}
\setlength{\cellspacetoplimit}{8pt}
\setlength{\cellspacebottomlimit}{8pt}
\newcolumntype{L}[1]{>{\raggedright\arraybackslash}S{p{#1}}}

\usepackage{amsmath}

\begin{document}

    \setlength\tabcolsep{1.5\tabcolsep}
    \setlength\arrayrulewidth{1.5pt}
    \begin{center}
        \begin{tabular}{!{\vrule width 1.5pt} L{75mm} !{\vrule width 1.5pt} L{75mm} !{\vrule width 1.5pt}}
            \hline
            As $\displaystyle f\left(x\right) \rightarrow +\infty$, & then $\displaystyle \dfrac{1}{f\left(x\right)} \rightarrow$
            \\ \hline
        \end{tabular}
    \end{center}

\end{document}

with macro \makegapedcells from the makecell pacakege. after removing all unnecessary code from your mwe the code of mwe is:

\documentclass[twoside,14pt]{extarticle}
\usepackage{array,
            makecell}   % new
\newcolumntype{L}[1]{>{\raggedright\arraybackslash}p{#1}}

\usepackage{amsmath}

\begin{document}
    \begin{center}
\setlength\tabcolsep{1.5\tabcolsep}
\setlength\arrayrulewidth{1.5pt}
\setcellgapes{5pt}
\makegapedcells
    \begin{tabular}{| L{75mm} |  L{75mm} |}
        \hline
        As $f(x) \rightarrow +\infty$, & then $\dfrac{1}{f(x)} \rightarrow$ \\
        \hline
    \end{tabular}
    \end{center}
\end{document}

note: this solution doesn't works with m columns type!
