LaTeX adjustbox shrinks table

Question

I've been having a strange issue with my LaTeX code with adjustbox. I'm currently using RMarkdown which converts markdown to LaTeX codes, and I'm having trouble narrowing down where it is causing the issue. I think showing .tex is the most relevant, but including RMarkdown just in case.

The original RMarkdown code

Here's my RMarkdown code:

---
title: "Untitled"
output: 
  pdf_document: 
    extra_dependencies: float
    number_sections: yes
    keep_tex: true
date: '2022-02-16'
header-includes:
  - \usepackage{booktabs}
  - \usepackage{geometry}
  - \usepackage{tikz}
  - \usepackage{adjustbox}
---

The outlook of pdf file : table shrunk and unreadable.

I'd appreciate any piece of information fixing this issue. Thank you.

It always helps to minimize the example, removing unneeeded packages. A smaller example is

\documentclass[

\usepackage{graphicx}
\makeatletter
\def\maxwidth{\ifdim\Gin@nat@width>\linewidth\linewidth\else\Gin@nat@width\fi}
\def\maxheight{\ifdim\Gin@nat@height>\textheight\textheight\else\Gin@nat@height\fi}
\makeatother
\setkeys{Gin}{width=\maxwidth,height=\maxheight,keepaspectratio}
% Scale images if necessary, so that they will not overflow the page
% margins by default, and it is still possible to overwrite the defaults
% using explicit options in \includegraphics[width, height, ...]{}

Producing

If you remove

\setkeys{Gin}{width=\maxwidth,height=\maxheight,keepaspectratio}

Then you get

If you globally set keys, you have to be sure nothing else is using the values. (I'm not sure why adjustbox is using the Gin key family here but...)

I couldn't put my finger on where it is causing issue so I thought showing all detail would be relevant. Thank you much, I should work on how to change keys on markdown then. — Matthew Son, Feb 16, 2022 at 20:26
No really you could have done as I did, delete the packages one at a time, putting things back if the problem goes. That's how I answered the question, I didn't guess the answer in advance (even though I wrote \setkeys originally) @MatthewSon — David Carlisle, Feb 16, 2022 at 20:29

Commenting out (or removing) code as suggested by David, which is great, could result in format breaking in RMarkdown (Quarto) for other figures.

Instead, overwriting the Gin part of the pandoc template code with

\setkeys{Gin}{width=\linewidth,height=\textheight,keepaspectratio}

is a more stable solution. (by puting in the YAML header such as include-in-header: in Quarto)
