這是一個後續問題我的上一個。
在這篇中,我想解決兩種情況:
第一的,按原樣加載表格,同時僅施加我自己的列標題和行標題。
第二,載入表格並旋轉它,然後施加我自己的列標題和行標題。
對於上述兩種情況,需要處理兩種不同類型的資料庫,如下所示
\documentclass{article}
\usepackage{datatool,filecontents,booktabs}
% 1st dataset
\begin{filecontents*}{data1.csv}
, col1 , col2 , col3
row1 , 11 , 12 , 13
row2 , 21 , 22 , 23
\end{filecontents*}
% 2nd dataset
\begin{filecontents*}{data2.csv}
11 , 12 , 13
21 , 22 , 23
\end{filecontents*}
\begin{document}
\section{First case: without rotation}
The desired output for both datasets should be
\begin{table}[h]
\centering
\caption{without rotation}
\begin{tabular}{@{}lccc@{}}
\toprule
& First Column & Second Column & Third Column\\
\midrule
First Row & 11 & 12 & 13 \\
\midrule
Second Row & 21 & 22 & 23 \\
\bottomrule
\end{tabular}
\end{table}
\section{Second case: with rotation}
The desired output for both datasets should be
\begin{table}[h]
\centering
\caption{with rotation}
\begin{tabular}{@{}lcc@{}}
\toprule
& First Column & Second Column\\
\midrule
First Row & 21 & 11 \\
\midrule
Second Row & 22 & 12 \\
\midrule
Third Row & 23 & 13 \\
\bottomrule
\end{tabular}
\end{table}
\end{document}
答案1
最好確保為兩個資料庫分配相同的鍵(透過keys
中的選項\DTLloaddb
)。這意味著鍵可以用於引用兩個資料庫中的同一列,即使它們具有不同的列索引:
\DTLloaddb[keys={rowheader,col1,col2,col3}]{database1}{database1.csv}
\DTLloaddb[noheader,keys={col1,col2,col3}]{database2}{database2.csv}
可使用以下鍵為兩個資料庫設定列標題:
\newcommand{\setdatabaseheaders}[1]{%
\DTLsetheader{#1}{col1}{First Column}%
\DTLsetheader{#1}{col2}{Second Column}%
\DTLsetheader{#1}{col3}{Third Column}%
}
\setdatabaseheaders{database1}
\setdatabaseheaders{database2}
但是,如果列標題在所有表之間共享,那麼借助etoolbox
的\csdef
命令以易於存取的方式儲存它們會更簡單:
\csdef{columnheader1}{First Column}
\csdef{columnheader2}{Second Column}
\csdef{columnheader3}{Third Column}
沒有行標題的概念,datatool
但很容易以類似的方式提供一些基於行索引的行標題:
\csdef{rowheader1}{First Row}
\csdef{rowheader2}{Second Row}
rowheader
顯示資料時需要忽略標識的列。可以使用 檢查此列是否存在\DTLifhaskey
。用於顯示資料的自訂命令可以透過引用以下給出的命令插入行標題\csname rowheader
idx\endcsname
(或者\csuse{rowheader
idx}
)在每行的開頭。對於列標題也是如此。

筆記:
\DTLloaddb
不會修剪尾隨空格,因此如果我沒有使用keys={rowheader,col1,col2,col3}
,第二、第三和第四列的鍵將包含尾隨空格。以下 MWE 無法運作:\documentclass{article} \usepackage{datatool} \begin{filecontents*}{database1.csv} ,col1 , col2 , col3 row1 , 11 , 12 , 13 row2 , 21 , 22 , 23 \end{filecontents*} \DTLloaddb{database1}{database1.csv} \DTLsetheader{database1}{col1}{First Column} \begin{document} \end{document}
這會產生錯誤
! Package datatool Error: Database `database1' doesn't contain key `col1'.
列標籤包含尾隨空格,因此分配需要為:
\DTLsetheader{database1}{col1 }{First Column}
前導空格被忽略,所以
\DTLsetheader{database1}{ col2 }{Second Column}
即使 CSV 檔案中有前導空格,也會產生錯誤。它需要是:
\DTLsetheader{database1}{col2 }{Second Column}
對於每個條目也是如此。例如:
\documentclass{article}
\usepackage{datatool}
\begin{filecontents*}{database1.csv}
,col1 , col2 , col3
row1 , 11 , 12 , 13
row2 , 21 , 22 , 23
\end{filecontents*}
\DTLloaddb{database1}{database1.csv}
\begin{document}
\DTLgetvalue{\thisvalue}{database1}{1}{2}`\thisvalue'.
\end{document}
這會產生:
前導空格將被忽略,但尾隨空格將被保留。
在此範例中,它沒有太大區別,因為使用keys
不包含任何空格來分配鍵。這些條目所在的tabular
環境中雜散空間不易察覺,但需要小心。
