表格标题中有多个标题，有些标题跨越多个单元格？

Question

我如何创建看起来像这样的表格？

My Title
-------------------------------------------
    Type 1                   Type 2
  ----------               ----------
colA colB colC  x    y   colF colG colH  z
-------------------------------------------
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
-------------------------------------------

如果我有格式的基表.csv？即：

colA,colB,colC,x,y,colF,colG,colH,z
aaa,bbb,ccc,ddd,eee,fff,ggg,hhh,iii
aaa,bbb,ccc,ddd,eee,fff,ggg,hhh,iii
aaa,bbb,ccc,ddd,eee,fff,ggg,hhh,iii
aaa,bbb,ccc,ddd,eee,fff,ggg,hhh,iii
aaa,bbb,ccc,ddd,eee,fff,ggg,hhh,iii
aaa,bbb,ccc,ddd,eee,fff,ggg,hhh,iii
aaa,bbb,ccc,ddd,eee,fff,ggg,hhh,iii

目标示例：

我知道csvsimple和autobooktabular，在那里可以做

\usepackage{adjustbox}
\usepackage{booktabs,csvsimple}

[...]

\begin{table}[ht]
\begin{adjustbox}{max width=0.9\textwidth}
\csvautobooktabular[table head={\toprule  alp & bet & gam & xx & yy & F & G & H & zz \\\midrule}]{csvs/test.csv}
\end{adjustbox}
\caption{blah blah blah etc.}
\label{tab:test}
\end{table}

它用指定的内容覆盖“head”列table head并创建

-------------------------------------------
alp  bet  gam   xx   yy   F    G    H    zz
-------------------------------------------
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
aaa  bbb  ccc  ddd  eee  fff  ggg  hhh  iii
-------------------------------------------

我不禁觉得应该可以使用它来保留文件的标题但插入额外的标题，尽管我似乎不知道如何做。

Answer 1

诀窍是使用\csvlinetotablerow包含第一行。

\documentclass{article}
\usepackage{adjustbox}
\usepackage{tabularx}
\usepackage{booktabs,csvsimple}
\begin{document}

\begin{table}[ht]
\begin{adjustbox}{max width=0.9\textwidth}
\csvautobooktabular[table head={\toprule  
   \multicolumn{3}{c}{Type 1} & & &  \multicolumn{3}{c}{Type 2} & \\
\cmidrule{1-3} \cmidrule{6-8} \csvlinetotablerow\\\midrule}]{test2.csv}
\end{adjustbox}
\caption{blah blah blah etc.}
\label{tab:test}
\end{table}

\end{document}
