在多行环境中使文本居中

我将非常感谢在多行环境中将文本居中的建议。在下面的表格中，多行文本“blah blah blah blah blah blah blah blah”并未在其跨越的九行上居中。

\begin{table}[]

\caption{}
\label{tab:my-table}
\resizebox{\textwidth}{!}{%
\begin{tabular}{@{}ccccccll@{}}

对于多行单元格内容的垂直居中，您需要估计其高度上应该有多少行文本：

相邻列 9 行 + 表格水平线周围 10 行 ~ 12 行

笔记： 我擅自在上述 MWE 中提出以下建议：

  • 对于列标题，请使用包thead中定义的指令makcell，
  • tabular删除多行单元格中的使用，并将其定义为\multirow{12}[5]{=}{...}其中[5]是多行单元格中的文本行数
  • 由于表格比较宽，最好tabular使用tabularx宽度规定为与文本宽度相等的表格（通过\linewidth}
