# Adding 3 multi-columns upside in a table

I have posted this code before. i now want to add two multi columns upside down to the same table jus like i have marked before and after table picture to make my point clear

Here is my code of picture no 1 i posted

\documentclass[journal]{IEEEtran}

\usepackage{multicol}

\usepackage{multirow}

\begin{table*}

\settowidth\rotheadsize{DIMENSIONS}

\renewcommand\multirowsetup{\centering}

\renewcommand{\arraystretch}{1.5}

\centering

\caption{Extreme Learning Machine(ELM) with kernel classifier accuracy of

combine reduced feature vectors whose individual classifier accuracy was low}

\begin{tabular}{|l|l| c |C{2.5cm}| c |C{2.5cm}|C{2cm}|C{2.5cm}|}

\hline

PCA as Dimension Reduction}
& \multirow{5}{=}{21 dimensions reduced to

• Missing many things to be a compilable code... please provide everything (but not more) needed to be able compile your code... – koleygr Feb 23 '18 at 2:52
• you mean packages? – user2102092 Feb 23 '18 at 9:25

since you not provide compilable mwe, i use my answer for your previous similar question to show principle how to make "multi paragraph" multi row cell. in it "paragraphs" can be separated between itself (only) with \newline command. for small vertical space between them seems to be ad \smallskip before \newline appropriate measure:

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


this should be simple to use/add in your table, for mine the complete mwe is:

\documentclass[journal]{IEEEtran}
\usepackage{multicol}
\usepackage{graphicx}
\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
