How do I center the text in the header for the Years row?

Question

I am using the following codes:

> \begin{table} [h!]    \caption{Alcohol- or Drug-Related Arrests By
> Ethnicity, 2017-2020}     \label{ASUS_drug_arrest_table}  \centering
>   \begin{tabular}{|p{4cm}|p{1.7cm}|p{1.7cm}|p{1.7cm}|p{1.7cm}|}  \hline
>       & 2017 & 2018 & 2019 & 2020\\ \hline    White/Caucasian &  &  &  &\\
>   \hline  Black/African American &  &  &  &\\     \hline  Hispanic/Latino
> &  &  &  &\\  \hline  Native American &  &  &  &\\    \hline  Asian &  &
> &  &\\    \hline  Hawaiian/Part Hawaiian &  &  &   &\\    \hline  Other
> Pacific Islander &  &  &   &\\    \hline  Other &  &  &   &\\     \hline
>   \end{tabular} \end{table}

and getting this output:

I was wondering how the top header representing years can be centered.

\documentclass[10pt,a4paper]{article}

\usepackage{booktabs, % new
            makecell, % new
            } 
\renewcommand\theadfont{\centering}

\begin{document}
    \begin{tabular}{p{4cm}p{1.7cm}p{1.7cm}p{1.7cm}p{1.7cm}}  \toprule
              & \thead{2017} & \thead{2018} & \thead{2019} & \thead{2020}\\ \midrule   White/Caucasian &  &  &  &\\
          \midrule  Black/African American &  &  &  &\\     \midrule  Hispanic/Latino
         &  &  &  &\\  \midrule  Native American &  &  &  &\\    \midrule  Asian &  &

EDIT

\documentclass[10pt,a4paper]{article}
    
\begin{document}
    \begin{tabular}{|p{4cm}|p{1.7cm}|p{1.7cm}|p{1.7cm}|p{1.7cm}|}  \hline
              & \thead{2017} & \thead{2018} & \thead{2019} & \thead{2020}\\ \hline   White/Caucasian &  &  &  &\\           \hline

\end{document}

I used the longtable package and it seems to give me what I wanted:

\begin{longtable}[h!]{|p{4cm}|p{2cm}|p{2cm}|p{2cm}|p{2cm}|}     
    \caption{Alcohol- or Drug-Related Arrests By Ethnicity, 2017-2020}
    \label{ASUS_drug_arrest_table} \\
    
    \hline \multicolumn{1}{|c|}{} & \multicolumn{1}{c|}{2017} & 
    \multicolumn{1}{c|}{2018} &
    \multicolumn{1}{c|}{2019} & 
    \multicolumn{1}{c|}{2020}\\ \hline 
        
    White/Caucasian &  &  &  &\\
    \hline
    Black/African American &  &  &  &\\
    \hline
    Hispanic/Latino &  &  &  &\\
    \hline
    Native American &  &  &  &\\
    \hline
    Asian &  &  &  & \\
    \hline
    Hawaiian/Part Hawaiian &  &  &   &\\
    \hline
    Other Pacific Islander &  &  &   &\\
    \hline
    Other &  &  &   &\\
    \hline
    
\end{longtable}
