我正在构建一个大表格（30x37，尽管我只会在 mwe 中包含几行），并努力使列间距适当。
到目前为止，虽然如果间距适当，文本足够小，可以适合页面，但列本身的尺寸小于文本和水平空间（如图所示）。出于某种原因，当宽度设置较低（尝试 5in）时，水平线不会填满页面，但列间距更合适。无论我调整第 3 列的大小（如图所示）还是仅使用 Y 列（定义为 X 列，文本居中），这种情况都会持续存在，如果我将所有 Y 列更改为 X 列，这种情况也会持续存在。无论我将宽度定义为 \textwidth、\hsize、\linewidth 还是 10.5in，似乎都不会改变它。
我做错了什么？
\documentclass[landscape]{article}
\usepackage[letterpaper,margin=.25in]{geometry}
\usepackage{amsmath,amssymb,amsthm,multicol,tabularx}
%center columns = Y
\newcolumntype{Y}{>{\centering\arraybackslash}X}
%multi-columns that are left-aligned
\newcommand{\mc}[2]{\multicolumn{#1}{l}{#2}} %e.g., \mc{4}{VAP}
%multi-rows that are centered
\newcommand{\mr}[2]{\multicolumn{#1}{*}{#2}} %e.g., \mr{5}{BPI}
\setlength{\parindent}{0em}
\begin{document}
\begin{tiny}
\begin{tabularx}{\linewidth}{*{2}{|Y}|p{5em}|*{34}{Y|}} %{|*{37}{Y|}}

答案1
我不认为你想要tabularx这里，因为这里没有换行符
\documentclass[landscape]{article}
\usepackage[letterpaper,margin=.25in]{geometry}
\usepackage{amsmath,amssymb,amsthm,multicol,tabularx}
%center columns = Y
\newcolumntype{Y}{>{\centering\arraybackslash}X}
%multi-columns that are left-aligned
\newcommand{\mc}[2]{\multicolumn{#1}{l}{#2}} %e.g., \mc{4}{VAP}
%multi-rows that are centered??? you used \multicolumn not row ???
\newcommand{\mr}[2]{\multicolumn{#1}{c}{#2}} %e.g., \mr{5}{BPI}
\setlength{\parindent}{0em}
\begin{document}
X\dotfill X
\setlength\tabcolsep{3pt}
\begin{tiny}
\begin{tabular*}{\linewidth}{@{\extracolsep{\fill}}*{2}{|c}|l|*{34}{c|}@{}} %{|*{37}{Y|}}
& & & \mc{4}{Era 1} & \mc{12}{Era 2} & \mc{14}{Era 3} & \mc{4}{Era 4} \\
& & & F06 & S07 & F07 & S08 & F08 & S09 & F09 & S10 & F10 & S11 & F11 & S12 & F12 & S13 & F13 & S14 & F14 & S15 & F15 & S16 & F16 & S17 & F17 & S18 & F18 & S19 & F19 & S20 & F20 & S21 & F21 & S22 & F22 & S23 \\ \hline
Loc & A123 & Long name & & & & & & & & & & & & & & & & & & & & & & & & & & & x & & & & & & & \\ \hline
\end{tabular*}

使用该包的替代方法tabularray：
\documentclass[landscape]{article}
\usepackage[letterpaper,margin=.25in]{geometry}
\usepackage{tabularray}
\begin{document}
\noindent\begin{tblr}{
cells={font=\tiny},
colspec={XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX},
columns={c},
column{3}={l},
colsep={1pt},
vlines
}
& & & \SetCell[c=4]{c} Era 1 &&& & \SetCell[c=12]{c} Era 2 &&&&&&&&&&& & \SetCell[c=14]{c} Era 3 &&&&&&&&&&&&& & \SetCell[c=4]{c} Era 4 &&& \\
& & & F06 & S07 & F07 & S08 & F08 & S09 & F09 & S10 & F10 & S11 & F11 & S12 & F12 & S13 & F13 & S14 & F14 & S15 & F15 & S16 & F16 & S17 & F17 & S18 & F18 & S19 & F19 & S20 & F20 & S21 & F21 & S22 & F22 & S23 \\ \hline
Loc & A123 & Long name & & & & & & & & & & & & & & & & & & & & & & & & & & & x & & & & & & & \\ \hline
\end{tblr}
