```tex
\begin{table}[htbp]
    \small
    \centering
    \caption{燃油效率与汽⻋价格}
    \begin{tabular}{lcc}
    \toprule
    & (1)        & (2)         \\
    \midrule
    燃油效率      & -238.90*** & -49.51 \\
    & (53.08)   & (86.16) \\
    汽车重量      &            & 1.75*** \\
    &           & (0.641)     \\
    常数项       & 11,253***  & 1,946 \\
    & (1,171)   & (3,597)     \\
    观测数       & 74         & 74 \\

### Include graphic with figure environment

Source: https://github.com/elegantlatex/elegantpaper/wiki/Graphics

Use the figure environment to include a graphic. Place images in subdirectories like ./image/, ./img/, ./figure/, or ./fig/ of the current working directory. The example loads scatter.pdf at 60% of text width with a caption and label.

```tex
\begin{figure}[htbp]
    \centering
    \includegraphics[width=0.6\textwidth]{scatter.pdf}
    \caption{Scatter Plot Example \label{fig:scatter}}
\end{figure}
```

\int_{R^q} f(x,y) dy.\emph{of \kern0pt f}
\end{equation}
```

### XeLaTeX font configuration with fontspec and xeCJK

Source: https://github.com/elegantlatex/elegantpaper/wiki/FontSettings

This snippet shows the font setup for XeLaTeX compilation, using fontspec and xeCJK packages. It sets Times New Roman as the main font, Arial as sans, and defines Chinese fonts (SimSun, KaiTi, Microsoft YaHei) with bold and italic variants. It also includes XeTeX linebreak settings and loads newtxmath. Note that the fonts are Windows-specific and may need substitution on Linux or macOS.

```tex
\RequirePackage{fontenc}
\RequirePackage[no-math]{fontspec}
\setmainfont{Times New Roman}[NFSSFamily=ntxtlf]
\setsansfont{Arial}
%\setmonofont[Scale=0.9]{Courier New}
\RequirePackage{xeCJK}
\RequirePackage{xunicode}
\setCJKmainfont[BoldFont={SimHei},ItalicFont={KaiTi}]{SimSun}
\setCJKsansfont[BoldFont={SimHei},ItalicFont={KaiTi}]{KaiTi}
\setCJKmonofont[BoldFont={SimHei},ItalicFont={KaiTi},Scale=0.9]{Microsoft YaHei}
\XeTeXlinebreaklocale "zh"
\XeTeXlinebreakskip = 0pt plus 1pt minus 0.1pt
\RequirePackage{newtxmath}
```

    \item Distributed storage and search.
\end{itemize}
```

\documentclass[bibend=bibtex]{elegantpaper}
```

--------------------------------

### Enable newtx fonts with math option

Source: https://github.com/elegantlatex/elegantpaper/blob/master/elegantpaper-en.tex

```latex
\documentclass[math=newtx]{elegantpaper}
```

--------------------------------

### Loading ctex for Chinese support

Source: https://github.com/elegantlatex/elegantpaper/blob/master/elegantpaper-en.tex

### Language mode options (lang=cn)

Source: https://github.com/elegantlatex/elegantpaper/blob/master/elegantpaper-en.tex

Sets the language to Chinese using the lang option. Both forms are equivalent. Under English mode (default), Chinese characters are not allowed.

```latex
\documentclass[lang=cn]{elegantpaper} % or
\documentclass[cn]{elegantpaper}
```

--------------------------------

### Update and uninstall ElegantPaper via tlmgr

Source: https://github.com/elegantlatex/elegantpaper/wiki/Installation

tlmgr uninstall elegantpaper 
```

--------------------------------

### Set lang option in elegantpaper class

Source: https://github.com/elegantlatex/elegantpaper/wiki/Languages

Use the lang option to set the language of captions, abstract name, and references. lang=en (default) keeps them English, while lang=cn makes them Chinese. The second line shows an alternative syntax that is also accepted.

```tex
\documentclass[lang=en]{elegantpaper}
\documentclass{en}{elegantpaper} % both ok
```

--------------------------------

### Changing bibliography style with citestyle and bibstyle

Source: https://github.com/elegantlatex/elegantpaper/blob/master/elegantpaper-en.tex

Sets the citation style to numeric-comp and the bibliography style to authoryear. These options are passed to biblatex.

```tex
\nocite{EINAV2010, Havrylchyk2018}
```

--------------------------------

### LaTeX error: Too many symbol fonts declared

Source: https://github.com/elegantlatex/elegantpaper/blob/master/elegantpaper-en.tex
