使用横向长桌进行工作

Question

我承认，在处理表格问题时，我处理得很糟糕。

在我的报告中，我想插入跨多页的表格（横向）。所以我使用了\longtable。

格式化是一个挑战：

1. 包含列表的列显示效果不佳
2. 必须\multicolumn反复使用才能调整多行单元格
3. 页码位置不正确。

以下是我所面临的问题的 MWE。

\documentclass{report}
\usepackage[utf8]{inputenc}
\usepackage{booktabs}
\usepackage{pdflscape}
\usepackage{afterpage}
\usepackage{makecell}
\renewcommand{\theadfont}{\normalsize\bfseries}
\usepackage{tabularx}
\usepackage{blindtext}
\usepackage{eso-pic,graphicx}
\usepackage{longtable}
\begin{document}

\section{Introduction}
\blindtext
\newpage
\begin{landscape}
\begin{longtable}{lclll }
\toprule
            \thead{Algorithm}  & \thead{Type of Problem} & \thead{Advantages}  & \thead{Disadvantages}  & \thead{Common Application areas} \\
            \midrule
 Decision Trees &  \multicolumn{1}{c}{supervised/unsupervised} & \multicolumn{1}{l}{
 \begin{itemize}
     \item robust to outliers and missing values
     \item item 2
     \item item 3
 \end{itemize}} &list advantages & some application areas\\
 \midrule
\end{longtable}
\end{landscape}
\end{document}

Answer 1

这是一个使用的解决方案长桌和枚举项。此外，我还定义了一个列，通过注入一个\@minipagetrue 和itemize通过将环境括在 中，将单元格与顶部基线对齐\parbox。作为奖励(?)，我可以删除 -commands\thead和所有\multicolumns：

Answer 2

我提出了这个解决方案，它基于对包的重新定义tabularx，该包带来了tabularx enumitemxltabular的功能。它远非完美，前两个列标题没有垂直对齐，原因我看不出来。longtable to, and
