删除左边距和右边距以获得更大的表格

Question

正如评论中已经解释的那样，您可以设置\LTleft并将\LTright扩展-1in到您使用包longtable设置的左边距和右边距：margin=1ingeometry

\documentclass{article} % or some other suitable document class

\usepackage[T1]{fontenc}
\usepackage[margin=1in]{geometry} % set page parameters appropriately
\usepackage{longtable}
\usepackage{booktabs} % for well-spaced horizontal rules
\usepackage{dcolumn}  % align numbers in columns on decimal markers
\newcolumntype{d}[1]{D..{#1}}

\newcommand{\mc}[1]{\multicolumn{1}{c}{#1}} % handy shortcut macro

\begin{document}

\begingroup % localize scope of next four instructions
\small      % 10% linear reduction in font size
\setlength\tabcolsep{0pt} % let LaTeX figure out inter-column space
\setlength\LTleft{-1in}% extend by left margin (see geometry option margin=1in) see p. 7 of package's user guide
\setlength\LTright{-1in}% extend by rightmargin (see geometry option margin=1in)

但在我看来，这个利润太少了：

因此你至少应该将longtable声明改为：

\begin{longtable}{@{\hspace{.25em}\extracolsep{\fill}} l *{7}{d{2.5}} d{2.6} @{\hspace{.25em}}}

（我将在下一个例子中展示结果。）

或者，如果整个文档不应该有左边距和右边距，则可以将left和设置right为 0in geometry：

您还可以删除顶部和底部边距。请参阅手册geometry以获取更多信息。

只是我的看法：我总是发现很难阅读那些列被人为加宽的表格。这在行中缺乏更多的方向，而且值的凝聚力也不足。因此，我一般不推荐这样做。

顺便说一句：设置\tabcolsep为 0pt 通常不是最好的主意。这会导致列相互紧挨而没有任何间距。
