我试图用宽表挤出水平页面的每一点空间，所以我想让表从靠近页面底部的位置开始，但仍然均匀地覆盖整个页面\linewidth。解决这个问题最优雅的方法是什么？
到目前为止的代码如下：
\documentclass[a4paper, oneside, 11pt]{report}
\usepackage[doublespacing]{setspace}
\usepackage{array,booktabs}
\usepackage[left=4cm, right=2cm, top=1.5cm, bottom=2.5cm]{geometry}

\usepackage{ltablex}
\newcolumntype{C}{>{\centering\arraybackslash}X}
\usepackage{subcaption}
\usepackage[table]{xcolor}

\usepackage{multirow}
\usepackage{lipsum}

所以它目前看起来是这样的。我对表格的宽度以及它在文档顶部的结束位置或多或少感到满意，但想在底部（页脚侧）使用更多的空间。
我尝试过许多解决方案（newgeometry、adjustwidth、v/hspace、textheight），但收效甚微。更改 textheight 似乎是最合适的，这样就可以tabularx跨越宽度，为其余单元格留出更多空间，但我似乎无法在事后将文档完全恢复到其原始状态，我想保持页脚间距等与文档的其余部分保持一致，但只是稍微回收该空间。
答案1
我所做的只是修改了调用tabularx以将否定包含\hspace在第三个参数中，如下所示
\begin{tabularx}{1.02\linewidth}{ @{\hspace{-12pt}}p{0.04\linewidth} CCCCCCCCCCCCCCCC }
这是 MWE。
