不使用表格来交替标记项目的背景颜色？

我想采用以下代码，并使行交替使用背景颜色，没有使用表格，因为这样会破坏两列，而不使用多列，因为这样会破坏浮动。这可能吗？

\documentclass[10pt,twocolumn]{article}
\usepackage[english]{babel}
\usepackage{scrextend}

\newcounter{foonum}
\newcommand{\roll}{
  \stepcounter{foonum}
  \arabic{foonum}
}

\begin{document}

\begin{labeling}{\textbf{roll}}
\item [\textbf{roll}] \textbf{item}
\item [\roll] Item
\item [\roll] Item

编辑：使用@Pouya 的答案，这就是我的想法。但我需要找到一种方法来减少或消除项目之间的巨大差距。

答案1

以下解决方案并不优雅，还有很大的改进空间。它使用计数器，foonum并检查值是否为奇数，然后根据奇数设置背景颜色。

有两点需要注意：1. 就目前情况而言，你应该更新item 命令和 2. 突出显示本身需要调整。对于后者，请参阅这全面的答案，自己尝试一下。我的答案只是一个起点...
