How to avoid table fitting the whole page?

Question

I would like my table to have the size of the text in the columns, not fit the whole page as currently is in the example at the bottom. Anyone knows how to fix this?

Code below:

\documentclass{article}
\usepackage[letterpaper,margin=2.5cm]{geometry}
\usepackage{pdflscape}
\usepackage{xltabular} 
\usepackage{ragged2e}  
\newcolumntype{L}{>{\RaggedRight\hangafter1\hangindent1em}X}
\usepackage{booktabs}
\newlength\mylen
\setlength\mylen{\textheight}

\begin{document}


\begin{xltabular}{\textwidth}{@{} ll @{}}

\caption{xxxxxxxxx xxxxxxxxx xxxxx xxx xxxxx xxxxxxxxxxxxxxxx xxxxxxxxx xxxxx xxx xxxxx xxxxxxx xxxxxxxxx xxxxxxxxx xxxxx xxx xxxxx xxxxxxx}
\label{tab:my-table}\\
\toprule
\textbf{xxxxxxxxx} & \textbf{xxxxxxxxx} \\ 
\midrule
\endfirsthead

\multicolumn{2}{@{}p{\textwidth}@{}}
{Table \thetable: xxxxxxxxx xxxxxxxxx xxxxx xxx xxxxx xxxxxxxxxxxxxxxx xxxxxxxxx xxxxx xxx xxxxx xxxxxxx xxxxxxxxx xxxxxxxxx xxxxx xxx xxxxx xxxxxxx (Continued)} \\ \addlinespace[14.4pt]
\toprule
\textbf{xxxxxxxxx} & \textbf{xxxxxxxxx} \\ 
\midrule
\endhead

\bottomrule
\endlastfoot

%% body of table
\multicolumn{2}{@{}l}{\textbf{xxxxxxxxxxx}} \\[0.25ex]
xxxxxxxxxx xxxxxxxxxx xxxx xxxxx xxxxxxxx xxxxxxxxxxxx & zzzz zzzz zzzz \\
xxxxxxx xxxxxxxx xxxxxx xxxxxx xxxxxx xxxxx xxxxx xx & zzzz zzzz zzzz \\
xxxxxxx xxxxxx xxxxxxxxx xxxxxx xxxxxxxxxx xxxxxx & zzzz zzzz zzzz \\
xxxxxxx xxxxxx xxxxxxxxx xxxxxx xxxxxxxxxx xxxxxxxxxxxxx & zzzz zzzz zzzz \\
xxxxxxx xxxxxx xxxxxxxxx xxxxxx xxxxxxxxxx xxxx & zzzz zzzz zzzz \\

\addlinespace 
\multicolumn{2}{@{}l}{\textbf{xxxxxxxxxxxx}} \\[0.25ex]
xxxxxxx xxxxxx xxxxxxxxx xxxxxx xxxxxxxxxx xxxxx & zzzz zzzz zzzz \\
xxxxxx xxxxxx xxxxxxxxxx xxxxxxx & zzzz zzzz zzzz \\
xxxxxxx xxxxxx xxxxxxx & zzzz zzzz zzzz \\
xxxxxxx xxxxxx xxxxxxxxx xxxxxx xxxxxxxx & zzzz zzzz zzzz \\
xxxxxxx xxxxxx xxxxxxxxx xxxxxx xxxxxxxxxx xxxxx & zzzz zzzz zzzz \\
xxxxxx xxxxxx xxxxxxxxxx xxxxxxx & zzzz zzzz zzzz \\

\end{xltabular}

\end{document}
