I'm making an equation sheet for an upcoming final, and in this includes a massive table of terms.

Really long table

But since I'm making this in a two column environment, I would ideally have the table be split between the two columns once it hits the end of a page / etc. Something like this. Split between two columns

My current code looks something like this:

\begin{multicols}{2}

\begin{table}[H]
    \centering
    \begin{tabular}{|c c|l|}
        \hline
        \textbf{Symbol} & & \textbf{Description} \\
        \hline
        $A$ & & Amps (C/s) \\

        ...        

        $\tau_p$ & & hole minority-carrier lifetime \\
        \hline
    \end{tabular}
    \caption{List of Symbols}
\end{table}

\end{multicols}

Is there a way to do this?

I wouldn't use a tabular-like environment for the material at hand. Instead, given that what you have looks very much like a list of pair-wise items, I would use a description environment. One of the (many!) useful features of list-like environments (such as itemize, enumerate, and description) is that breaking material across columns and even pages is an entirely normal affair that doesn't require making any special efforts.

I would definitely use the \si macro, which is provided by the siunitx package, to typeset the scientific units.

enter image description here

\documentclass{article}
\usepackage[a4paper,margin=2.5cm]{geometry} % set page parameters suitably
\usepackage{multicol,siunitx,amssymb,enumitem,ragged2e}
\sisetup{per-mode=symbol,inter-unit-product={\cdot}}
\newlength\mylen
\settowidth\mylen{$\si{\joule}_{N\mid\mathit{drift}}$} % widest symbol

\begin{document}
\subsection*{Symbols and Descriptions} % choose an appropriate header

\begin{multicols}{2} % use 'multicols*' if column-balancing is not desired
\RaggedRight
\begin{description}[labelwidth=\mylen,nosep]

\item[\si{\ampere}] Amps (\si{\coulomb\per\second})
\item[$D_N$] electron diffusion coefficient (\si{\centi\meter\squared\per\second})
\item[$\mathcal{E}$] Electric field
\item[$\dots$]
\item[\si{\joule}] Joule (\si[per-mode=reciprocal]{\kilo\gram\meter\squared\per\second\squared})
\item[\si{\joule}] Joule (\si{\ampere\per\centi\meter\squared})
\item[$\si{\joule}_{N\mid\mathit{diff}}$] electron diffusion current density
\item[$\si{\joule}_{N\mid\mathit{drift}}$] electron drift current density
\item[$\si{\joule}_{P\mid\mathit{diff}}$] hole diffusion current density
\item[$\si{\joule}_{P\mid\mathit{drift}}$] hole drift current density
\item[$\dots$]
\item[\si{\volt}] Voltage (\si[per-mode=reciprocal]{\kilo\gram\meter\squared\per\second\cubed\per\ampere})
\item[$\dots$]
\item[$N_v$] effective density of valence band states
\item[$\dots$]
\item[$\tau_n$] electron minority-carrier lifetime
\item[$\tau_p$] hole minority-carrier lifetime

\end{description}
\end{multicols}
\end{document}

    I did not realize that description and the si units were a thing, thank you much!

You could use supertabular and \twocolumn as shown in the following example. (Depending on your documentclass and if the whole document should be typeset in two columns you might also be interested in the twocolumn option.)

\documentclass[11pt,a4paper]{article}
\usepackage[margin=1.5cm]{geometry}
\usepackage{supertabular}

\begin{document}
\twocolumn
\tablehead{    \textbf{Symbol} &  \textbf{Description} \\ \hline}
\bottomcaption{a caption}
\begin{supertabular}{|c l|}
    $A$ &  Amps (C/s) \\
    $\tau_p$ &  hole minority-carrier lifetime \\
        $A$ &  Amps (C/s) \\
    $\tau_p$ &  hole minority-carrier lifetime \\
        $A$ &  Amps (C/s) \\
    $\tau_p$ &  hole minority-carrier lifetime \\
        $A$ &  Amps (C/s) \\
    $\tau_p$ &  hole minority-carrier lifetime \\
        $A$ &  Amps (C/s) \\
    $\tau_p$ &  hole minority-carrier lifetime \\
        $A$ &  Amps (C/s) \\
    $\tau_p$ &  hole minority-carrier lifetime \\
        $A$ &  Amps (C/s) \\
    $\tau_p$ &  hole minority-carrier lifetime \\
        $A$ &  Amps (C/s) \\
    $\tau_p$ &  hole minority-carrier lifetime \\
        $A$ &  Amps (C/s) \\
    $\tau_p$ &  hole minority-carrier lifetime \\
        $A$ &  Amps (C/s) \\

    $\tau_p$ &  hole minority-carrier lifetime \\
        $A$ &  Amps (C/s) \\
    $\tau_p$ &  hole minority-carrier lifetime \\
    \hline

\end{supertabular}

Depending on the width of the contents of your description column, you might also want to consider using a p type column that allows for automated linebreaks.
