带有 S 说明符的列中的“e+08”（不抑制 0）符号

Question

出于对称原因，在大型表格中我希望采用 2 位数字的科学计数法格式（即 e+08）。默认情况下，它会隐藏 0。

这是我的做法：

 \documentclass[]{article}

 \usepackage{siunitx}


 \begin{document}

 \begin{table}[htbp]
 \begin{center}
 \footnotesize
 \def\fix#1{\sisetup{output-exponent-marker=\mathrm{e+}}#1}
 \sisetup{output-exponent-marker = \mathrm{e},exponent-product = {},retain-explicit-plus,retain-zero-exponent,table-format=+1.4e+2}
 \begin{tabular}{lSS}
 Sample & {$\mu_1 [Pa]$} & {$\alpha_1 [-]$} \\ \hline
 {Isotropic $10\%$ MREs} & 1.5030e+09 & \fix{4.2384e+00} \\ 
 & 6.7175e+10 & 8.4376e-01 \\
 & 6.7175e+08 & 8.4376e-01  \\ \hline 
 \end{tabular}
 \end{center}
 \caption[]{Scientific notation $e+9$, but for symmetry reasons I would like $e+09$}
 \label{tab:example}
 \end{table}

 \end{document}

这就是输出：

非常感谢你的帮助！Gerlind

Answer 1

如果您不介意使用，pgfplotstable您可以使用尾数和指数表达式来获得一些乐趣，并且非常接近。作为奖励，表格输入稍微容易一些，并且对齐显然是自动发生的（没有进行广泛检查）。

\documentclass[]{article}
\usepackage{siunitx,pgfplotstable,booktabs}
\pgfplotsset{compat=1.10}% put your installed version no.
\pgfplotstableset{mycol/.style={
        sci,
        sci zerofill,
        sci precision=4,
        sci generic={
            mantissa sep={e\pgfmathparse{####1<0?"-":"+"}{\pgfmathresult}},
            exponent={%
            \pgfmathparse{abs(####1)<10?0:}\pgfmathresult%
            \pgfmathparse{int(abs(####1)}%
            \pgfmathprintnumber[int detect]{\pgfmathresult}%
            }
        }
    }
}
\begin{document}
\pgfplotstabletypeset[
columns/sample/.style={string type,column name=Sample},
columns/mu/.style={mycol,column name={$\mu_1$ [\si{\pascal}]}},

]{

}
\end{document}

Answer 2

回答 1 之后我想补充一下我最后做的事情。最终的表格比问题中建议的表格更复杂，并且使用了更多的功能pgfplotstable。

\documentclass[]{article}
\usepackage{siunitx,pgfplotstable}
\usepackage{rotating}   
\usepackage[bf,footnotesize]{caption}   
\usepackage{multirow}   
% To increase space of some rows in tables, especially needed before and after \hline
\newcommand\T{\rule{0pt}{2.6ex}}         % Top strut
\newcommand\B{\rule[-1.2ex]{0pt}{0pt}} % Bottom strut
% pgfplot setup
\pgfplotsset{compat=1.8}% put your installed version no.
\pgfplotstableset{
mysci/.style={sci,sci zerofill,sci precision=4,sci sep align,sci generic={mantissa sep={e\pgfmathparse{##1<0?"-":"+"}{\pgfmathresult}},exponent={\pgfmathparse{abs(##1)<10?0:}\pgfmathresult\pgfmathparse{int(abs(##1)}\pgfmathprintnumber[int detect]{\pgfmathresult}}}},
myfixed/.style={fixed,precision=4,dec sep align,fixed zerofill}
}
