如何垂直对齐表格列

Question

我正在努力垂直对齐下表列内的文本。我希望获得这种垂直对齐以提高表格的可读性...我尝试在交替行上添加颜色，但它取消了行的左右板。如果您知道如何解决这个问题，请也添加它。

谢谢

Answer 1

正如您所说的“垂直对齐”，如果您指的是示例中的列名和行名（例如“聚合物，聚合物共混物”），则另一种方法是：

\newcommand\minitab[2][c]{\begin{tabular}{@{}#1@{}}#2\end{tabular}}
\begin{tabular}{|c|l|c|r|}
  \hline
  & \minitab[l]{Column\\ 1} & \minitab{Column\\ 2} & \minitab[r]{Column\\ 3}\\
  \hline
  \minitab{Multiple\\ line} & 2 & 2 & 2\\
  \hline
  Single & 1 & 1 & 1\\
  \hline
\end{tabular}
