在表格上方添加 3 个多列

Question

我之前发布过此代码。现在我想将两个多列倒置添加到同一个表中，就像我在表格图片前后标记的那样，以明确我的观点

这是我发布的第 1 张图片的代码

\documentclass[期刊]{IEEEtran}

combine reduced feature vectors whose individual classifier accuracy was low}

Answer 1

由于您不提供可编译的 mwe，我使用我的答案对于您之前的类似问题，展示了如何制作“多段落”多行单元格的原理。在其中，“段落”可以用\newline命令（仅）在其自身之间分开。对于它们之间的小垂直空间似乎是 \smallskip在`\newline 之前的广告适当的措施：

\multirow{5}{=}{Correlation as Dimension Estimator,
                PCA as Dimension Reduction\smallskip\newline                                        
                Add Multicol here\smallskip\newline  
                Add Multicol here
                }

这应该很容易使用/添加到您的表中，对于我来说，完整的 mwe 是：

\documentclass[journal]{IEEEtran}
%\usepackage{array} % loaded twice
\usepackage{multicol}
\usepackage{graphicx}
\usepackage{rotating}% added, for rothead
\usepackage{array, makecell, multirow, tabu}{\centering\let\newline\\\arraybackslash\hspace{0pt}}m{#1}}
\newcolumntype{C}[1]{>{\centering\arraybackslash}m{#1}}% in this table is better use this definition
