Eu postei esse código antes. agora quero adicionar duas colunas múltiplas de cabeça para baixo à mesma tabela, assim como marquei a imagem antes e depois da tabela para deixar meu ponto claro
Aqui está o meu código da imagem nº 1 que postei
\documentclass[diário]{IEEEtran}
\usepackage{multicol}
\usepackage{multilinha}

combine reduced feature vectors whose individual classifier accuracy was low}

já que você não fornece mwe compilável, eu usominha respostapara sua pergunta semelhante anterior para mostrar o princípio de como criar uma célula de várias linhas "multiparágrafo". nele "parágrafos" podem ser separados entre si (apenas) com \newlinecomando. pois o pequeno espaço vertical entre eles parece ser um anúncio \smallskipantes de `\newline medida apropriada:
\multirow{5}{=}{Correlation as Dimension Estimator,
PCA as Dimension Reduction\smallskip\newline
Add Multicol here\smallskip\newline
Add Multicol here
}
isso deve ser simples de usar/adicionar em sua tabela, para o meu o mwe completo é:
\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
\begin{document}
\begin{table*}
\settowidth\rotheadsize{DIMENSIONS}
\renewcommand\multirowsetup{\centering}
\renewcommand{\arraystretch}{1.5}
\centering
\caption{Extreme Learning Machine(ELM) with kernel classifier having reduced dimension of feature vectors individual accuracy}
\begin{tabular}{|l|l|c|C{2.5cm}|c|C{2.5cm}|C{2cm}|C{2.5cm}|}
\hline

}
& \multirow{5}{=}{26 dimensions reduced to 4 dimensions}
& \multirow{5}{=}{Combine accuracy of 4 dimensional
reduced Feature Vector is 68\%\smallskip\newline
Add Multicol here\smallskip\newline
Add Multicol here
} \\
\cline{1-2} \cline{5-5}
GO & 4D & & & ELM & & & \\
\cline{1-2} \cline{5-5}

que dá:
