[Tex/LaTex] Left align caption of table

captionstables

I try to left align the caption to my table. When I use the according code it is indeed left-aligned but is more left than the table. How could I fix this?

Thanks a lot,

Julia

this is my code:

\documentclass{article}
\usepackage[utf8]{inputenc,caption}
\usepackage{booktabs}
\usepackage{siunitx}
  \captionsetup{labelfont=bf,
              justification=raggedright,
              singlelinecheck=false}
\begin{document}

\begin{table}[htbp]

  \centering

  \caption{Percentage of Missing Values in the Analysis Variables}
\begin{tabular}{lS}
\textbf{Variable} & {Percent missing}\\
\toprule
\textbf{x} & 9.37 \\
\textbf{Lxon} & 0.94 \\
\textbf{x} & 0 \\
\textbf{x} & 0.04 \\
\textbf{x} & 0.34 \\
\textbf{Exl} & 7.93 \\
\textbf{Rxe} & 15.32 \\
\textbf{Sxm} & 8.69 \\
\textbf{Txal} & 4.43 \\
\textbf{x} & 1.33 \\
\textbf{Nxnces} & 0.9 \\
\textbf{xs} & 1.12 \\
\textbf{Fxans} & 0 \\
\textbf{xxation} & 2.4 \\
\textbf{Cxon} & 0.58 \\
\textbf{xg} & 0 \\
\textbf{x x} & 0.22 \\
\textbf{x to x from x o. x} & 1.03 \\
\textbf{x to x} & 0.76 \\
\textbf{x} & 0.99 \\
\textbf{x} & 0.09 \\
\textbf{x} & 0.83 \\
\bottomrule
\end{tabular}%
  \label{tab:addlabel}%
\end{table}%

Citing from the threeparttable package:

This package facilitates tables with titles (captions) and notes. The title and notes are given a width equal to the body of the table (a tabular environment). By itself, a threeparttable does not float, but you can put it in a table or a table* or some other floating environment. (This causes extra typing, but gives more flexibility.)

So, threeparttable package directly addresses your problem. There are other options like \parbox or setting \captionsetup{width=..}, but are less flexible.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{booktabs,caption,threeparttable}
\usepackage{siunitx}
\captionsetup{labelfont=bf,
              justification=raggedright,
              singlelinecheck=false}
\begin{document}

\begin{table}[!htbp]

\begin{tabular}{>{\bfseries}lS}

[Tex/LaTex] Align table caption with left border of longtable

I don't know why the table doesn't stretch. But here's an alternative, replacing ltablex with the more recent longtabu environment. Another longtabu example directly compared to an ltablex one can be found in the answer to Ltablex customize caption.

\documentclass[12pt,a4paper,oneside]{article}
\usepackage[left=35mm,right=15mm,top=2cm,bottom=2cm,bindingoffset=0cm]{geometry}
\usepackage[utf8x]{inputenc} % указать кодировку русского текста
\usepackage[russian]{babel} % указать, что язык текста - русский

\usepackage{cmap}

\usepackage{makeidx}
\makeindex

\usepackage{indentfirst} 
\setlength{\parindent}{1.25cm}

\usepackage{caption}
\captionsetup[table]{labelsep=endash}

\usepackage{longtable}
\usepackage{tabu}
\usepackage{lipsum}
\begin{document}
%    \keepXColumns
        \begin{longtabu} to \textwidth {| l | X |} 

        \caption{A long description of this awesomest table ever. No, seriously. Worth repeating: A long description of this awesomest table ever. No, seriously. }\\
        \hline 
        First & Second\\ \hline \hline
        \endfirsthead
        \captionsetup{singlelinecheck=off}
        \caption{A short one}\\
        \hline 
        First & Second\\ \hline
        \endhead
        Lols & \lipsum[150] \\ \hline

[Tex/LaTex] How to left align caption inside subtable

To your question:

subcaption package supports the caption package and use its \captionsetup interface.

    \usepackage{caption}
      \captionsetup[table]{justification=raggedright}
      \captionsetup[subtable]{justification=raggedright}

where raggedright is left aligned.

In the problem subfigure-and-subfig-packages-deprecated, subcaption is recommended.

\usepackage{subcaption}

instead of subfigure.

And I change your subtable environment style:

\begin{table}[H]
  \begin{subtable}[b]{0.48\textwidth}
    % -----------------------------------------------------%
    \caption{Half-life for $^{108}$Ag} \label{lefttable}
    \begin{tabular}{c@{\hskip 1cm} c}
      \hline\noalign{\smallskip}
      Accepted $T_{1/2}$ & Experimental $T_{1/2}$\\
      (s) & (s)\\
      \hline\noalign{\smallskip}
      142.92 & 158 $\pm$ 7\\
      \hline\noalign{\smallskip}
    \end{tabular}
    % -----------------------------------------------------%  
  \end{subtable}
  \begin{subtable}[b]{0.48\textwidth}
    % -----------------------------------------------------%
    \caption{Half-life for $^{110}$Ag}     \label{righttable}
    \begin{tabular}{c@{\hskip 1cm} c}
      \hline\noalign{\smallskip}
      Accepted $T_{1/2}$ & Experimental $T_{1/2}$\\
      (s) & (s)\\
      \hline\noalign{\smallskip}
      24.6 & 21 $\pm$ 2\\
      \hline\noalign{\smallskip}
    \end{tabular}
    % -----------------------------------------------------%
  \end{subtable}
  \caption{2 Column tables side by side}
  \label{sidebysidetable}
\end{table}

And output is enter image description here

Noting that the overall width (lefttable + righttable) should be less than \textwidth. And the option in [b] is vertical position for that sub-table. In your case, same height tables would make b and t no difference.
