I am trying to make a table where cells have colored backgrounds.
I am using \colorcell{}, and it works fine with one line of numbers.
However, I would need two lines in each cell. To make two lines, I have tested the makecell package, but the cells are not completely color-filled.
The table is the following:
\documentclass{IEEEtran}
\ifCLASSOPTIONcompsoc
\usepackage{subfig}
\else
\usepackage{subfig}
\fi
\usepackage{graphicx}
%
\usepackage{makecell}
\makeatletter
% \newcommand\nst{\@setfontsize\nst\@vipt\@viipt}
% \newcommand\nst{\@setfontsize\nst{6}{7}}
\newcommand\nst{\@setfontsize\nst{6.31415}{7.1828}}
\makeatother
\usepackage{array}
\usepackage{tabularx}
\usepackage[symbol]{footmisc}
\renewcommand{\thefootnote}{\fnsymbol{footnote}}
\usepackage{threeparttable}
\usepackage[dvipsnames]{xcolor}
\newcommand{\celdat}[1]{ \footnotesize \bf #1 }
\newcommand{\celdah}[1]{ \footnotesize \bf #1 }
\newcommand{\celda}[1]{\scriptsize #1}
\newcommand{\celdas}[1]{\nst #1}
\usepackage{colortbl}
\usepackage{enumerate}
\colorlet{l1}{Peach!100}
\colorlet{l2}{Green!80}
\colorlet{l3}{Cerulean!100}
\colorlet{l4}{Yellow!100}
\colorlet{lD1}{Peach!40}
\colorlet{lD2}{Green!40}
\colorlet{lD3}{Cerulean!40}
\colorlet{lD4}{Yellow!40}
\begin{document}

\begin{table}[t]

I am also reducing the size font to fit the two lines into each cell.
