Graphics, Figures & Tables ⇒ Aligning mathematical equations vertically in a table - Overleaf

[joeTex]

Hi

I would like to align equations - which are separately inserted into table cells - vertically along the red line - as shown in the figure below:

The above is a small excerpt of a large table with multiple rows and columns (text columns to the left and right of the image too) - I have tried a multitude of methods, but have not been successful. I am using Overleaf.

Has anybody had success in implementing this? If so, I would really appreciate the assistance of the community by means of a small minimal working code example?

Thanks a lot

[Bartman]

Why don't you show us one of your attempts using a minimal working example so that we don't have to enter the content of the table shown?

Code: Select all

@Bartman; Thanks for the reply - see the MWE above. I have made it work partially; however there is an error (which I do not understand) and an offset in the table column which I cant seem to remove (most probably due to my limited experience). Is there any other method which would work better, or did I just miss the boat completely on this one?

[Bartman]

The first required argument of the \parbox command expects a length.

My proposition:

Code: Select all

\documentclass[
%    a4paper, fontsize=11pt,% default setting
    oneside
]{scrbook}

\usepackage{amsmath}
\usepackage{siunitx}% provides S column type

% Read the manual of the array package to find out, 
% how you can use >{} and <{} to set declarations.
% siunitx loads array.
\newcolumntype{C}{>{$}c<{$}}

\begin{document}
\begin{table}[htbp]
    \centering
    \begin{tabular}{
        *2C
        S[table-format=3.2]
        C@{\;$\Delta x\leq$\;} 
        C
        S[table-format=2]
    }
    x & b_2        &  20.25 & 0.91 \leq & 3.30 & 12 \\
    x & r_n        &  55    & 1.50 \leq & 1.83 & 10 \\
    x & \Delta r_n &   0    &           & 0.34 & 4  \\
    x & r_1        & 105.45 & 2.17 \leq & 2.17 & 8  
    \end{tabular}
\end{table}
\end{document}

@Bartman: Thanks a lot, I was also thinking of physically splitting the column into two separate columns then to right and left align the adjacent cells to simulate a merged & aligned column. Unless somebody else has another method to achieve the same result - I suppose this will do just fine.

I played with this a little bit. I modified the code from @Bartman a little bit, just to make it a little more simple to use (well, according to my limited experience using this platform). See below:

Code: Select all

\documentclass[
%    a4paper, fontsize=11pt,% default setting
    oneside
]{scrbook}
 
\usepackage{amsmath}
\usepackage{siunitx}% provides S column type
 
% Read the manual of the array package to find out, 
% how you can use >{} and <{} to set declarations.
% siunitx loads array.
\newcolumntype{C}{>{$}c<{$}}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%% Bartman's method, changed a bit - below %%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\begin{document}
\begin{table}[htbp]
    \centering
    \begin{tabular}{
        c
        c %*2C
        c %S[table-format=3.5]
        C@{\;$\Delta x\leq$\;} 
        c %C
        c %S[table-format=3]
    }
    x & $b_2$        &  20.25 & 0.91 \leq & 3.30 & 12 \\
    x & $r_n$        &  55    & 1.50 \leq & 1.83 & 10 \\
    x & $\Delta r_n$ &   0    &           & 0.34 & 4  \\
    x & $r_1$        & 105.45 & 2.17 \leq & 2.17 & 8  
    \end{tabular}
\end{table}

\end{document}

I also tried to just shift the adjacent columns to "brute force" the alignment - I think I was successful (or at least partially), this will also allow for alignment between different kinds of markers, see below:

Code: Select all

\documentclass[
%    a4paper, fontsize=11pt,% default setting
    oneside
]{scrbook}
 
\usepackage{amsmath}
\usepackage{siunitx}% provides S column type
 
% Read the manual of the array package to find out, 
% how you can use >{} and <{} to set declarations.
% siunitx loads array.

\newcolumntype{R}{>{\raggedright\arraybackslash}r@{\hspace{3pt}}} %New column type, change right spacing and left align
\newcolumntype{L}{>{\raggedleft\arraybackslash}l} %New column type, right align, no change in left spacing


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%% My method - below %%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
\begin{document}
\begin{table}[htbp]
    \centering
    \begin{tabular}{
        c
        c %*2C
        c %S[table-format=3.5]
        R %C@{\;$\Delta x\leq$\;} 
        L %c %C
        c %S[table-format=3]
    }
    x & $b_2$        &  20.25 & $0.91 \leq$ & $\Delta x\leq 3.30$ & 12 \\
    x & $r_n$        &  55    & $1.50 \leq$ & $\Delta x\leq 1.83$ & 10 \\
    x & $\Delta r_n$ &   0    &             & $\Delta x\leq 0.34$ & 4  \\
    x & $r_1$        & 105.45 & $2.17 \leq$ & $\Delta x\leq 2.17$ & 8  
    \end{tabular}
\end{table}

\end{document}

But yes, several methods to achieve the same goal - some more elegant than others, but still - thanks for the input @Bartman, it is really highly appreciated.

[Bartman]

In the second example the beginning of the document environment is missing.

Much obliged, I was additionally considering truly parting the section into two separate segments at that point to both ways adjust the nearby cells to reenact a blended and adjusted segment. Except if another person has another strategy to accomplish a similar outcome - I guess this will do fine and dandy.
