將相鄰兩列中的文字對齊

Question

我怎樣才能添加第2行。 3號線。在第二行第一列中，以便它們與第二列中的對應項對齊？

只需在相關之前添加 then 即可&：

\documentclass{article}

\usepackage{amsmath}
\usepackage{amssymb}

\begin{document}

\begin{table}[ht!]

\begin{tabular}{|c|l|}

  $ A_{\theta}'|_{\theta = 0.5} = \begin{bmatrix} -2.000 & 0.8776\\ 2.0000 & 1.0000\\ 0.8415 & 0.2500\\ 1.0000 & 2.0000\\ -0.8415 & 1.7500\\ 0.7500 & 1.0000 \end{bmatrix}$\\

請注意，它a4wide已被棄用（並且有錯誤）；也不newlfont應該在新文件中使用。我刪除了範例中不需要的套件。

也是^{'}錯的，應該是公正的'。

我還建議對錶採用不同的方法，使用booktabs.垂直規則被抑制，\addlinespace可用於提供更多空間並更好地分隔行。
