如何使长的 \twocolumn 超表格适合页面宽度？

Question

我的表格很长，占据了报告中太多的空间。没有那么多信息，所以我想我可以将表格打印在一页上的两列上，从而将页面需求减少一半。我发现supertabular这很容易实现。然而，事实证明我的表格有点太宽了，无法实现这一点。我现在想将表格放在左侧，这样它就不会像这样重叠，但\hspace我放进去的任何内容似乎都没有太大影响。我怎样才能将它移到左边，以便它能正确放置？

\documentclass{article}
\usepackage{supertabular}

\begin{document}

\twocolumn
\tablehead{\textbf{Code} &  \textbf{Branch} &   \textbf{Date and time} & \textbf{Duration} \\}

\begin{supertabular}{llll}
