我有一个包含三个表格的文档。这三个表格目前对于页面来说太长了，所以我想让两个表格并排显示，然后让第三个表格显示在它们下面。这样，所有表格都可以放在同一页中。
这是我的 MWE：
\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{microtype}
\usepackage[margin=2.54cm]{geometry}
\usepackage{graphicx,booktabs,tabularx}
\usepackage[table]{xcolor}
\usepackage{array}
%define some nice colors
\definecolor{middleware_green}{RGB}{82, 119, 17}
\definecolor{middleware_white}{RGB}{255, 255, 255}
\definecolor{middleware_light_gray}{RGB}{239, 239, 239}
\definecolor{middleware_dark_gray}{RGB}{153, 153, 153}
\renewcommand{\tabularxcolumn}[1]{>{\small}m{#1}}
\newcolumntype{L}{>{\leavevmode\ignorespaces\raggedleft\arraybackslash\sffamily}X}%
\newcolumntype{C}{>{\leavevmode\ignorespaces\centering\arraybackslash\sffamily}X}%
\rowcolors{2}{middleware_white}{middleware_light_gray}

我该如何实现这一点？如何才能让这三个表格适合一页？
答案1
表格环境使用与字母相同的规则来定位，例如X它们仅在垂直方向上间隔开，因为每个段落之间都有一个段落分隔符（空行）。
