我收到一个警告Overfull \hbox (... too wide)...为什么会发生这种情况？我该如何解决？

答案1

有问题的是你的第二个表格。它比列宽还宽。可以使它变窄，但是表格的内容是未知的，因此在实际文档中获得的结果可能不起作用。

在此处输入图片描述

如您所见，我改变了表格布局。现在看起来更好了。为此，我添加了两个新包：booktabs用于规则和siunitx用于S列类型。我还假设列标题的内容是最宽的单元格内容。

\documentclass[10pt,twocolumn,letterpaper]{article}
\usepackage{siunitx}
\usepackage{array, booktabs}
\newcommand\mc[1]{\multicolumn{1}{>{\bfseries}c}{#1}}

\usepackage{lipsum}

    \label{Sec:results}
\lipsum[22]

    \begin{table}[htb]

多于姆韦没有错误，没有警告，没有坏框。
