一页内可折叠狭长表格

Question

我有一张包含 1000 行（可变，可以是任意）和 3 列（固定）的表格。每个单元格都有一个 10 位数字。

以单行连续流的方式显示它看起来不太好，并且没有最大限度地利用可用的打印空间。

我希望它从当前点显示到当前页面的末尾。其余行必须折叠并显示到页面底部，并且该过程应持续到页面中有足够的宽度。后续行应按照相同逻辑进入后续页面。最后一组行应从页面顶部均匀分布，以便最后一行包含与第一行相同的列数。

此外，列标题需要在每个列实例中重复。如果可能的话，行和列之间要显示线条。

提前致谢。Aravind

有以下可能性：

\documentclass{article}
\usepackage{multicol}
\usepackage{capt-of}
\usepackage{siunitx}

\usepackage{lipsum} % just for the example

\newcommand{\entry}[3]{%
  \makebox[\columnwidth][s]{\num{#1}\hfil\num{#2}\hfil\num{#3}}\par
}
\newenvironment{pseudotabular}[1]% the argument is the caption
 {\setlength\columnsep{1cm}%
  \begin{multicols}{2}[\captionof{table}{#1}]
  \footnotesize
  \setlength\parindent{0pt}}
 {\end{multicols}}

\begin{document}

You can see the result in table~\ref{long}.

\lipsum[2]

\begin{pseudotabular}{A long table\label{long}}
\entry{1010101010}{2121212121}{3232323232}
\entry{1010101010}{2121212121}{3232323232}
\entry{1010101010}{2121212121}{3232323232}
\entry{1010101010}{2121212121}{3232323232}
...
\end{pseudotabular}

\end{document}

另一种可能性是xtab，但欺骗它自动获得平衡的列几乎是不可能的。

看使用新命令将 Supertabular 转换为 Multicols和http://www.guitex.org/home/en/forum/5-tex-e-latex/26889-supertabular-e-twocolumn-riempimento-parziale-altezza-testo

\documentclass{article}
\usepackage{multicol,capt-of}
