横向表格：我可以在 \afterpage{} 内使用 \toprule 吗？

我正在尝试使用景观桌。我偶然发现了这问题，我正在尝试修改它以获得更漂亮的表格。我想使用诸如 之类的命令\toprule来绘制水平线。

以下是我的看法：

\documentclass{article}

\usepackage{pdflscape}
\usepackage{afterpage}
\usepackage{capt-of}% or use the larger `caption` package

\usepackage{lipsum}% dummy text
\begin{document}
\lipsum % Text before
\afterpage{%
    \clearpage% Flush earlier floats (otherwise order might not be correct)
    \thispagestyle{empty}% empty page style (?)
    \begin{landscape}% Landscape page
        \centering % Center table
        \begin{tabular}{llll}
            \toprule
            A & B & C & D \\
            \bottomrule
        \end{tabular}
        \captionof{table}{Table caption}% Add 'table' caption
    \end{landscape}
    \clearpage% Flush page
}
\lipsum % Text after
\end{document}

不幸的是它不能编译。

我收到以下错误：

and I'll forget about whatever was undefined.

有什么办法可以解决这个问题吗？我也想以类似的方式使用 tabularx 包。

安德里亚，祝你好运
