如何将这个长数组转换为具有四列的长表？

Question

我有一个很长的阵列

 \documentclass[12pt,a4paper]{article}
    \usepackage[utf8]{inputenc}
    \usepackage{amsmath}
    \usepackage{amsfonts}
    \usepackage{amssymb}
    \usepackage{graphicx}
    \usepackage{fourier}
    \usepackage[left=2cm,right=2cm,top=2cm,bottom=2cm]{geometry}
    \usepackage{array,longtable}\begin{document}
    \[
\left(
\begin{array}{cc}  \{18,24,30\} & \left(
\begin{array}{ccc}
 -16 & 8 & 16 \\
 -6 & 12 & -12 \\
 0 & 0 & 0 \\
\end{array}
\right) \\
 \{18,24,30\} & \left(
\begin{array}{ccc}
 -16 & 8 & 16 \\
 -4 & 20 & 22 \\
 0 & 0 & 0 \\
\end{array}
\right) \\
 \{18,24,30\} & \left(
\begin{array}{ccc}
 -16 & 8 & 16 \\
 0 & 0 & 0 \\
 6 & -12 & 12 \\
\end{array}
\right) \\
 \{18,24,30\} & \left(
\begin{array}{ccc}
 -16 & 16 & -8 \\
 -12 & -6 & 12 \\
 0 & 0 & 0 \\
\end{array}
\right) \\
 \{18,24,30\} & \left(
\begin{array}{ccc}
 -12 & -6 & 12 \\
 -4 & 10 & 28 \\
 0 & 0 & 0 \\
\end{array}
\right) \\
 \{18,24,30\} & \left(
\begin{array}{ccc}
 -12 & -6 & 12 \\
 0 & 0 & 0 \\
 4 & -22 & 20 \\
\end{array}
\right) \\
 \{18,24,30\} & \left(
\begin{array}{ccc}
 -12 & -6 & 12 \\
 0 & 0 & 0 \\
 16 & -16 & 8 \\
\end{array}
\right) \\
\end{array}
\right)
 \]   
 \end{document}

现在我想转换成形式（我在这里看到如何对齐长数组？）

\begin{longtable}{| *{4}{>{$}c<{$}} | }
\endfirsthead  % blank header on first page
\multicolumn{4}{@{}l}{(\emph{array continued from previous page})}
\endhead
\multicolumn{4}{r@{}}{(\emph{array continued on next page})}
\endfoot
\endlastfoot 
\{18,24,30\} & (-16, 8, 16) & (-6, 12, -12) & (0,0,0)\\ 
\{18,24,30\} & (-16, 8, 16) & (-4, 20,22) & (0,0,0)\\ 
\{18,24,30\} & (-16, 8, 16) &  (0,0,0)  &  (6,-12,12)\\
\end{longtable}

在longtable：

• 数组的左列是longtable的第一列（从左到右）；

• 在右列中，第一行是 longtable 的第二列（从左到右）；第二行是 longtable 的第三列，第三行是 longtable 的第四列。

我该如何转换它？

我还使用 pmatrix 简化了子数组。为了好玩，我使用 TikZ 在左侧和右侧添加了顶部和底部。

\documentclass[12pt,a4paper]{article}
    \usepackage[utf8]{inputenc}
    \usepackage{amsmath}
    \usepackage{amsfonts}
    \usepackage{amssymb}
    \usepackage{graphicx}
    \usepackage{fourier}
    \usepackage[left=2cm,right=2cm,top=2cm,bottom=2cm]{geometry}
    \usepackage{array,longtable}
    \usepackage{tikz}

\begin{document}
\begin{longtable}{| *{2}{>{$}c<{$}} | }
\endfirsthead  % blank header on first page
\multicolumn{2}{@{}l}{(\emph{array continued from previous page})}
\endhead
\multicolumn{2}{r@{}}{(\emph{array continued on next page})}
\endfoot
\endlastfoot
% start of table
\multicolumn{2}{@{\tikz[overlay,xshift=.2pt,yshift=-4.3pt]{\draw (0,0) to[in=180,out=90] (5pt,5pt);}}c%
  @{\tikz[overlay,xshift=-.2pt,yshift=-4.3pt]{\draw (-5pt,5pt) to[in=90,out=0] (0,0);}}}{ }\\
\{18,24,30\} & \begin{pmatrix}
 -16 & 8 & 16 \\
 -6 & 12 & -12 \\
 0 & 0 & 0
\end{pmatrix}\\
\{18,24,30\} & \begin{pmatrix}
 -16 & 8 & 16 \\
 -4 & 20 & 22 \\
 0 & 0 & 0
\end{pmatrix}\\
\multicolumn{2}{@{\tikz[overlay,xshift=.2pt]{\draw (0,10pt) to[in=180,out=270] (5pt,5pt);}}c%
  @{\tikz[overlay,xshift=-.2pt]{\draw (-5pt,5pt) to[in=-90,out=0] (0,10pt);}}}{ }\\
\end{longtable}
\end{document}
