如何才能使各列的宽度相等？

我试图使面板 B 中“预测变量”下的两列宽度相等。

我查看了其他在线问题。我尝试使用，tabularx但没有用。

有人可以帮帮我吗？

以下是我的代码。

答案1

  1. 我添加了一些快捷方式，因此代码更容易阅读。

    • \mc为了\multicolumn
    • \dc为了\multicolumn{2}{l|}{#1}

  2. 取而代之\usepackage{tabu}​\usepackage{tabularx}

答案2

在此处输入图片描述

  • 首先我清理前言：不是\usepackage{graphics, graphicx, ...}足够了 \usepackage{graphicx, ...}，而是\usepackage{xcolor, color, colortbl}足够了\usepackage[table]{xcolor}，amsmath被加载了两次
  • 使用tabu很脆弱；软件包有缺陷，而且不幸的是不再维护
  • 为了更好地对齐最后两列中的数字，使用S包中的列类型很方便siunitx；用它写数字乘以也更简单10^{...}（参见下面的 MWE）
  • 而不是（例如）$\hat \epsilon_{r^e,t-1} \hat \epsilon_{\Delta c_{i},t-1}$是正确的$\hat{\epsilon}_{r^e,t-1} \hat{\epsilon}_{\Delta c_{i},t-1}$
  • 我不清楚SVAR，，NIPA... 是一个变量还是四个变量的集合；我假设前者并将它们写为\mathit{SVAR}等
  • tabularx对于等宽列，您需要规定它们的宽度。您可以按照建议使用马苏皮兰在他的回答中，我将

\begin{tabularx}{\linewidth}{p{2.7cm}|
                >{\centering}p{\myLength}|
                >{\centering}p{\myLength}|
                >{\centering}Xc}`

到

\begin{tabularx}{\linewidth}{l}|
           *{2}{>{\centering}X|}
           *{2}{S[table-format=2.3]}}

用于下面的 MWE（tabularx当然也在序言中添加包）或使用p{...}列类型，如下面的 MWE 中所示：
