从破折号开始水平对齐两行，第一行前一行没有下标，第二行前一行有下标

从破折号开始水平对齐两行，第一行前一行没有下标，第二行前一行有下标

我尝试在 2 个单词后水平对齐 2 行，第一行在文本中不包含下标（参见下面的“WL”），第二行包含下标（参见 GC_{sp}）。

我为此尝试了多次，例如\hphantom或“ \,”，但都不起作用。如您所见，前两个左破折号“-”符号之间有一点偏移。

想要从“-”符号对齐

我希望第一行上的第一个左破折号“ -”符号从水平对齐的角度与第二行位于相同的位置，即稍微向右移动。

这里是代码片段：

fisher_1.name = '\\parbox{9in}{ $ \\mathrm{WL\\hphantom{ } - Opt. Flat. No \gamma -} \\mathrm{FoM=47.05} $ }'
fisher_2.name = '\\parbox{9in}{ $ \\mathrm{GC_{sp} - Opt. Flat. No \gamma -} \\mathrm{FoM=60.49} $ }

如果有人能有办法解决这个问题......

编辑1：

和从库中注入到以下结构fisher_1.name中：fisher_2.namecosmicfish

fisher_list = fpa.CosmicFish_FisherAnalysis(
    fisher_list=[
        fisher_1,
        fisher_2,
    ],
)

我记得我希望第一个“-”符号从水平对齐的角度来看位于相同的水平位置，这意味着从第一个破折号“-”符号到字符串末尾的完美对齐（47.05和60.49。

最后的解决方案：

fisher_1.name = '\\parbox{9in}{$\\mathrm{WL}$\\hphantom{$\\mathrm{_{sp}}$} - FoM=47.05}'
fisher_2.name = '\\parbox{9in}{$\\mathrm{GC_{sp}}$ - FoM=60.49}'

不起作用。我无法弥补下标引起的差距_{sp}

编辑2：唯一可行的解​​决方案基本上是：

fisher_1.name = 'WL   - Opt. Flat. No gamma - FoM=47.05'
fisher_2.name = 'GCsp - Opt. Flat. No gamma - FoM=60.49'

这使 ：基本解，无下标

使用建议的其他解决方案时，由于我在带有库的代码中定义fisher_1.name并出现了编译错误。fisher_2.namePython[cosmicfish][3]

如果我想要希腊符号 \gamma，这个基本解决方案不再起作用：

fisher_1.name = 'WL   - Opt. Flat. No $\gamma$ - FoM=47.05'
fisher_2.name = 'GCsp - Opt. Flat. No $\gamma$ - FoM=60.49'

相同：

fisher_1.name = 'WL   - Opt. Flat. No $\\gamma$ - FoM=47.05'
fisher_2.name = 'GCsp - Opt. Flat. No $\\gamma$ - FoM=60.49'

我很失望，它不适用于您的所有解决方案。我不知道该怎么办……

编辑3：我尝试使用我的 Python 代码中实现的这个示例从头开始重新开始：

fisher_1.name = '\\parbox{\\widthof{$\\mathrm{GC_{sp}}$}}{$\\mathrm{WL}$}  $\\mathrm{-\\ Opt.\\ Flat.\\ No\\ \\gamma - FoM=47.05} $'
fisher_2.name = '\\parbox{\\widthof{$\\mathrm{GC_{sp}}$}}{$\\mathrm{GC_{sp}}$}  $\\mathrm{-\\ Opt.\\ Flat.\\ No\\ \\gamma - FoM=60.49} $'

在执行 Python 代码时，出现以下错误：

编辑4：部分解决方案已完成：

    fisher_1.name = '\\parbox{9in}{\\rlap{$\\mathrm{WL}$}\\hphantom{$\\mathrm{GC_{sp}}$} - FoM=47.05}'
    fisher_2.name = '\\parbox{9in}{$\\mathrm{GC_{sp}}$ - FoM=60.49}'

快完成了

如您所见，出于我忽略的原因，“WL”字符串被推到了顶部，我不知道为什么。字符串“FoM=47.05”和“FoM=60.49”的字体也很奇怪。

-因此，由于尊重了第一个破折号“ ”的对齐，我们已经接近解决方案。

解决方案 ：已被以下人员发现Heiko Theiße：

这两行代码起了作用：

   fisher_1.name = '\\rlap{$\\mathrm{WL}$\\hphantom{\\mathrm{GC_{sp}}} - FoM=47.05'
   fisher_2.name = 'GC_{sp} - FoM=60.49'

生成：解决方案

问候

答案1

\hphantom{\mathrm{GC_{sp}}}\llap{$\mathrm{WL}$}在第一行和GC_{sp}第二行中使用。\hphantom产生与一样宽的空间GC_{sp}，并将\llap排版$\mathrm{WL}$到该空间中，右对齐。

在第一行使用\rlap{$\mathrm{WL}$}\hphantom{\mathrm{GC_{sp}}}会使其左对齐。

附录：以下工作：

fisher_1.name = '\\rlap{$\\mathrm{WL}$}\\hphantom{\\mathrm{GC_{sp}}} - FoM=47.05'
fisher_2.name = 'GC_{sp} - FoM=60.49'

挑战在于cosmicfish单独编译行（每行运行一次 LaTeX），因此\halign无法使用表格包。

答案2

你可以通过以下方式将宽度的计算留给 LaTeXeqparbox's \eqmakebox[<tag>][<align>]{<stuff>}。它将<stuff>所有 s 的最大宽度放入一个框内，<tag>并提供单独的 ment 选项<align>（left、right 或center）。它需要对最宽元素的宽度进行两次编译，以进行任何更改。

在此处输入图片描述

\documentclass{article}

\usepackage{eqparbox}

\setlength{\parindent}{0pt}% Just for this example

\begin{document}

\eqmakebox[LHS][l]{WL} -- Opt.\ Flat.\ No $\gamma$ - FoM = 47.05

\eqmakebox[LHS][l]{GC\textsubscript{sp}} -- Opt.\ Flat.\ No $\gamma$ - FoM = 60.49 

\end{document}

答案3

繁體

Aparbox仅用于第一个“单词”。其宽度设置为固定长度或使用calc包根据最长值计算。

第一种选择更好。你不需要额外的包，而且很容易定义一个 \newlength{<width to fit the longest first word used>}{\mywidth}

然后始终适用\parbox{\mywidth}{<first word>}。

不需要额外的编译。

\documentclass{article}

\usepackage{calc} % \widthof{..}

\begin{document}
    
    \textbf{Original}\medskip
        
    \parbox{9in}{ $ \mathrm{WL\hphantom{ } - Opt. Flat. No \gamma -} \mathrm{FoM=47.05} $ }
    
    \parbox{9in}{ $ \mathrm{GC_{sp} - Opt. Flat. No \gamma -} \mathrm{FoM=60.49} $ }    
        
    \bigskip
    \textbf{A fixed length}\medskip
        
    \parbox{5ex}{$\mathrm{WL}$}  $\mathrm{-\ Opt.\ Flat.\ No\ \gamma - FoM=47.05} $
    
    \parbox{5ex}{$\mathrm{GC_{sp}}$}   $\mathrm{-\ Opt.\ Flat.\ No\ \gamma - FoM=60.49} $ 
    
    \bigskip
    \textbf{Using calc}\medskip 
    
    \parbox{\widthof{$\mathrm{GC_{sp}}$}}{$\mathrm{WL}$}  $\mathrm{-\ Opt.\ Flat.\ No\ \gamma - FoM=47.05} $
    
    \parbox{\widthof{$\mathrm{GC_{sp}}$}}{$\mathrm{GC_{sp}}$}  $\mathrm{-\ Opt.\ Flat.\ No\ \gamma - FoM=60.49} $
