Vertically center textwidth table

Question

Sorry for this question but I'm new using LaTeX. I have a table which width is set to be \textwidth using tabularx{\textwidth} and one of its rows will have 3 or 4 lines. This is my current code:

\renewcommand{\arraystretch}{1.2}
    \arrayrulecolor{gray}
    \begin{table}[b!] % hbtp
        \centering
        \begin{tabularx}{\textwidth}{ c | c | X }
            \arrayrulecolor{black} 
            \hline
            \textbf{$e_\#$} & \textbf{Time interval} & \textbf{Topic} \\ 
            \hline
            \arrayrulecolor{gray}
            1 & \makecell{From: 2019-04-15 20:30:05 \\ To: 2019-04-15 21:30:05} & \textbf{díamundialdelarte, 15deabril:} enfocat(0.94), meningitis(0.94), construyendolarepública(0.94), 14deabril(0.68), ley(0.66), españa(0.62)  \\
            \hline
            2 & \makecell{From: 2019-04-15 09:00:05 \\ To: 2019-04-15 17:00:05} & \textbf{gracias:} semana(0.61), muchísimas(0.64) \\
            \hline
            3 & \makecell{From: 2019-04-15 19:30:05 \\ To: 2019-04-16 01:00:05} & \textbf{notre:} dame(0.98), catedral(0.92), incendio(0.76), parís(0.91), historia(0.73), humanidad(0.77), llamas(0.74), paris(0.64), tristeza(0.65)  \\
            \hline
        \end{tabularx}
        \caption{April 15th 2019 top 3 events}
        \label{tab:mabed-impact}
    \end{table}
    \arrayrulecolor{black}
    \renewcommand{\arraystretch}{1.5}

and this is its visualization:

I would like that:

• All the cells were vertically centered
• Columns 1 and 2 were horizontally centered
• Column 3 were horizontally left aligned, but its header (row 1) were horizontally centered

How can achieve this?

UPDATE:

\begin{table}[hbtp]
        \centering
        \renewcommand{\tabularxcolumn}[1]{m{#1}}
        \begin{tabularx}{\textwidth}{ c c >{\RaggedRight}X }
            \toprule
            \textbf{$e_\#$} & \textbf{Time interval} & \makecell[cc]{\textbf{Topic}} \\ 
            \midrule
            1 & \begin{tabular}[t]{r@{:~}l} From & 2019-04-15 20:30:05 \\ To & 2019-04-15 21:30:05\end{tabular} & \textbf{díamundialdelarte, 15deabril:} enfocat(0.94), meningitis(0.94), construyendolarepública(0.94), 14deabril(0.68), ley(0.66), españa(0.62)  \\\addlinespace

            2 & \begin{tabular}[t]{r@{:~}l}From& 2019-04-15 09:00:05 \\ To & 2019-04-15 17:00:05\end{tabular} & \textbf{gracias:} semana(0.61), muchísimas(0.64) \\ \addlinespace
            3 & \begin{tabular}[t]{r@{:~}l}From & 2019-04-15 19:30:05 \\ To & 2019-04-16 01:00:05 \end{tabular} & \textbf{notre:} dame(0.98), catedral(0.92), incendio(0.76), parís(0.91), historia(0.73), humanidad(0.77), llamas(0.74), paris(0.64), tristeza(0.65)  \\
            \bottomrule
        \end{tabularx}
        \caption{April 15th 2019 top 3 events}
        \label{tab:mabed-impact}
    \end{table}

Answer 1

You can redefine the tabularx X type column to be vertically centered using \renewcommand{\tabularxcolumn}[1]{m{#1}}. With the makecelll package that you already use, you can also change the horizontal (and vertical) alignment of a single cell. Combining these, you can achieve the following result:

\documentclass{article}
\usepackage{geometry}
\usepackage{tabularx}
\usepackage{makecell}
\usepackage[table]{xcolor}
\usepackage{array}
\renewcommand{\tabularxcolumn}[1]{m{#1}}
\begin{document}


    \begin{table}
    \renewcommand{\arraystretch}{1.2}
    \arrayrulecolor{gray}
        \centering
        \begin{tabularx}{\textwidth}{ c | c | X }
            \arrayrulecolor{black} 
            \hline
            \textbf{$e_\#$} & \textbf{Time interval} & \makecell[cc]{\textbf{Topic}} \\ 
            \hline
            \arrayrulecolor{gray}
            1 & \makecell{From: 2019-04-15 20:30:05 \\ To: 2019-04-15 21:30:05} & \textbf{díamundialdelarte, 15deabril:} enfocat(0.94), meningitis(0.94), construyendolarepública(0.94), 14deabril(0.68), ley(0.66), españa(0.62)  \\
            \hline
            2 & \makecell{From: 2019-04-15 09:00:05 \\ To: 2019-04-15 17:00:05} & \textbf{gracias:} semana(0.61), muchísimas(0.64) \\
            \hline
            3 & \makecell{From: 2019-04-15 19:30:05 \\ To: 2019-04-16 01:00:05} & \textbf{notre:} dame(0.98), catedral(0.92), incendio(0.76), parís(0.91), historia(0.73), humanidad(0.77), llamas(0.74), paris(0.64), tristeza(0.65)  \\
            \hline
        \end{tabularx}
        \caption{April 15th 2019 top 3 events}
        \label{tab:mabed-impact}
    \end{table}


    \end{document}

Personally, I would suggest a slightly different design (less horizontal and no vertical lines, aligning th : in the second column):

\documentclass{article}
\usepackage{geometry}
\usepackage{tabularx}
\usepackage{makecell}
\usepackage{array}


\usepackage{booktabs}
\begin{document}

    \begin{table}
        \centering
        \begin{tabularx}{\textwidth}{ c  c  X }
            \toprule
            \textbf{$e_\#$} & \textbf{Time interval} & \makecell[cc]{\textbf{Topic}} \\ 
            \midrule
            1 & \begin{tabular}[t]{r@{:~}l} From & 2019-04-15 20:30:05 \\ To & 2019-04-15 21:30:05\end{tabular} & \textbf{díamundialdelarte, 15deabril:} enfocat(0.94), meningitis(0.94), construyendolarepública(0.94), 14deabril(0.68), ley(0.66), españa(0.62)  \\\addlinespace

            2 & \begin{tabular}[t]{r@{:~}l}From& 2019-04-15 09:00:05 \\ To & 2019-04-15 17:00:05\end{tabular} & \textbf{gracias:} semana(0.61), muchísimas(0.64) \\ \addlinespace
            3 & \begin{tabular}[t]{r@{:~}l}From & 2019-04-15 19:30:05 \\ To & 2019-04-16 01:00:05 \end{tabular} & \textbf{notre:} dame(0.98), catedral(0.92), incendio(0.76), parís(0.91), historia(0.73), humanidad(0.77), llamas(0.74), paris(0.64), tristeza(0.65)  \\
            \bottomrule
        \end{tabularx}
        \caption{April 15th 2019 top 3 events}
        \label{tab:mabed-impact}
    \end{table}


\end{document}

Lastly, some spaces seem to be missing in the text. Are díamundialdelarte and construyendolarepública really only one word?
