[Tex/LaTex] \captionsetup{option} does not work for table

Question

I have a problem with the \captionsetup{}

First of all, singlelinecheck=off does not work for my table, nor does any other option I define for my table, e.g. labelfont=bf.

Interestingly it works for figures in the same document.

Does anybody have a suggestion?

Here is my code:

\documentclass[journal=jacsat,manuscript=article]{achemso}

\usepackage[version=3]{mhchem} % Formula subscripts using \ce{}
\usepackage{caption}
\usepackage[colorlinks, linkcolor = black, citecolor = black, filecolor = black, urlcolor = blue]{hyperref}
%\usepackage{cleveref}
\usepackage{upgreek}

\newcommand*\mycommand[1]{\texttt{\emph{#1}}}

 \end{figure}

\end{document}

I tried to pre-define the singlelinecheck=off at the beginning of the document when loading the caption package. Unfortunately, I get an error message stating that I already loaded the package when I do this.

Thanks in advance!

Hope it works now; this is the achemso Latex template

Answer 1

This provides hanging indents (and I've removed the \begin{center}...\end{center} pair in the floating table.

The error is most likely due to a missing \title{...} statement!

singlelinecheck=off as an option to the caption package works too!
