[Tex/LaTex] Align along dot in tables

horizontal alignmenttables

Does anyone know how to align the figure along dot within the tabular environment? I would like the figures to be under each other sharing the decimal dot as a common point of alignment.

  \begin{table}[H]
    \caption{My table}
    \centering 
    \begin{tabular}{lccc}
    \toprule
            &  A            & B         & C         \\ \midrule
    D       & 0.00      & +171.00   &  +135.00   \\ 
    E               & +233.00   & +123.00   &  0.00   \\    
    F       & $-240.00$     & $-20.00$      & $-1590.00$ \\
    G               & $-56.00$      & +68.00        & $-95.00$   \\ \bottomrule
    \end{tabular}
    \end{table}

Thank you very much for your help!

Use »siunitx« and its S column type.

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{caption}
\usepackage{booktabs}
\usepackage{siunitx}

\begin{document}
  \begin{table}[!ht]
    \caption{My table}
    \centering
    \begin{tabular}{
      l
      S[table-format=-3.2]
      S[table-format=-3.2]
      S[table-format=-4.2]
    }\toprule
        & {A}     & {B}    & {C}      \\ \midrule
      D &    0.00 & 171.00 &   135.00 \\
      E &  233.00 & 123.00 &     0.00 \\
      F & -240.00 & -20.00 & -1590.00 \\
      G &  -56.00 &  68.00 &   -95.00 \\ \bottomrule
    \end{tabular}
  \end{table}
\end{document}

More formatting options are shown in the package manual.

[Tex/LaTex] Two tables in one line, problem with text between tables

@Hadson, Code in your link is far from a MWE ... Anyway, you have two problems:

you request from tables (with empty line between them) to be each in new line
second tables are to wide to both fits in one line in text width.

For show what I do, I made from your code the following MWE:

For first two table it was enough to erase empy line between the. For quick test I made distance between them with quad. Instead it you can use hfill associated with \centeringcommand after \begin{table}.

For second two table was my suspect in comment right. They are to wide. So, you see how to make columns with heads Liczba okresów k and Czas t[s] dla k okresów narrower. One way to do this is typeset them in more lines as I do in above MWE: in preamble add package makecell and then use its macro thead.

As you can see, I add to tables option [t] for aligning on top (since the first two are of different heights). Pictures of both tables after aforementioned suggestions:

The reason you're getting a "missing $ inserted" error message is that siunitx doesn't manage to parse the terms $\dot{W}^{M1}$ and $\dot{W}^{M2}$ correctly. As they're written, these terms satisfy LaTeX's own syntax rules for math formulas. See the following paragraph for a modification that helps out the siunitx parser.

One solution is to enclose the terms in curly braces, effectively hiding them from siunitx's parser. A second solution is to enclose the two \dot{W} terms in curly braces, i.e., to write ${\dot{W}}^{M1}$ and ${\dot{W}}^{M2}$ , respectively. With this method, there's no need to encase the full terms in curly braces -- siunitx parses them correctly and they will be centered automatically.

Incidentally, the column specification *7S[table-format=-3.2] isn't really optimal, as (for instance) none of the numbers feature minus (or plus) symbols. If you want well-spaced (and well-centered) columns, it's worth specifying differing formats for column 1, columns 2-5, and columns 6 and 7, along the lines used in the code below.

\documentclass{article}
\usepackage{booktabs}
\usepackage{siunitx}
\begin{document}
\begin{table}
\centering
\begin{tabular}{@{}S[table-format=1.2]
              *{4}{S[table-format=2.2]}
              *{2}{S[table-format=3.2]}@{}}
\toprule
$\varphi$ & a & $\xi$ & $\alpha$ & $\beta$ & ${\dot{W}}^{M1}$ & ${\dot{W}}^{M2}$ \\
\midrule
0.00 & 45.00 & 22.48 &  0.02 &  0.17 & 250.00 & 250.00 \\
1.00 & 45.50 & 52.21 & 44.82 & 38.39 & 236.86 & 236.72 \\
\bottomrule
\end{tabular}
\end{table}
\end{document}
