I want to center the text in each entry of my table:

usepackage{array}

documentclass[11pt, a4paper]{article}

begin{document}

begin{table}[h]

centering

begin{tabular*}{0.80textwidth}{| @{extracolsep{fill} } c||c|c|}

    hline

     & textbf{Monday} & textbf{Wednesday}\

    hline

    Week 1 & August 27 & August 29\

    & 1.1, 1.2 & 1.3, 1.4\

    hline

    Week 2 & September 3 & September 5\

    & color{darkred}NO CLASScolor{black}& 2.1, 2.2\

    & & Chapter 1 Quiz\

    hline

    Week 3 & September 10 & September 12\

    & 2.3, 2.4 & 2.5\

    hline

    Week 4 & September 17 & September 19\

    & 3.1, 3.2 & 3.3, 3.4\

    & & Chapter 2 Quiz\

    hline

    Week 5 & September 24 & September 26\

    & 4.1, 4.2 & 4.3, 4.4, 4.5\

    & & Chapter 3 Quiz\

    hline

    Week 6 & October 1 & October 3\

    & 5.1, 5.2 & 5.3, 5.4\

    & & Chapter 4 Quiz\

    hline

    Week 7 & October 8 & October 10\

    & 5.5 & 5.6\

    hline

    Week 8 & October 15 & October 17\

    & 6.1 & 6.2\

    & & Chapter 5 Quiz\

    hline

    Week 9 & October 22 & October 24\

    & Midterm Review & Midterm\

    hline

end{tabular*}

end{table}

end{document}

Maybe this is what you want? I replaced tabular* with tabularx and added an improvement with package hhline:

documentclass[11pt, a4paper]{article}

usepackage[svgnames]{xcolor}

usepackage{tabularx, multirow}

usepackage{hhline}



begin{document}



begin{table}[h]

centeringsetlength{extrarowheight}{2pt}

begin{tabularx}{0.80textwidth}{|l||*{2}{>{centeringarraybackslash}X|}}

    hhline{~--}

  multicolumn{1}{c}{} & multicolumn{1}{|c}{textbf{Monday}} & textbf{Wednesday}\

    hhline{~--}

noalign{vspace{doublerulesep}}

    hhline{-||--|}

    Week 1 & August 27 & August 29\

    & 1.1, 1.2 & 1.3, 1.4\

    hhline{-||--|}

    Week 2 & September 3 & September 5\

    &multirow{2}{=}{centeringtextcolor{DarkRed}{NO CLASS}}& 2.1, 2.2\

    & & Chapter 1 Quiz\

    hhline{-||--|}

    Week 3 & September 10 & September 12\
