根据两列中的位置设置不同的环境设置（也考虑图形环境）

Question

我询问了使用列表环境根据位置将行号放在左侧或右侧。

根据两列中的位置设置不同的环境设置

代码运行正常，但是当我将环境放在图形环境中时，行号的方向就错了。

考虑到浮动环境中的情况，是否有可能找到文档的正确一侧？我需要浮动环境来为源代码制作标题。

这是代码：

为了制作标题，我可以使用 caption 包。提示来自无浮动的标签和标题。

\documentclass[conference]{IEEEtran}
\usepackage{listings}
\usepackage{lipsum}
\usepackage{caption}
\usepackage{color}

\DeclareCaptionType{mytype}[Code][List of mytype]
\newenvironment{code}{}{}
\definecolor{delim}{RGB}{20,105,176}

\lstdefinelanguage{rruby}{
        escapechar=\,
        basicstyle=\scriptsize\ttfamily,
        numberstyle=\scriptsize\ttfamily,
        stepnumber=1,
        numbersep=3pt,
        showstringspaces=false,
        breaklines=true,
        frame=lines,
        %backgroundcolor=\color{background},
        literate=
         *{0}{{{\color{numb}0}}}{1}
            {1}{{{\color{numb}1}}}{1}
            {2}{{{\color{numb}2}}}{1}
            {3}{{{\color{numb}3}}}{1}
            {4}{{{\color{numb}4}}}{1}
            {5}{{{\color{numb}5}}}{1}
            {6}{{{\color{numb}6}}}{1}
            {7}{{{\color{numb}7}}}{1}
            {8}{{{\color{numb}8}}}{1}

            {\}}{{{\color{delim}{\}}}}}{1}
            {[}{{{\color{delim}{[}}}}{1}
            {]}{{{\color{delim}{]}}}}{1},
            }
