Change font size in Table

Question

How do I change the font size in my table?

I have tried the \normalsize and \small commands, but it doesnt make any difference. I needed to specify column length to get the design I wanted, does this have something to do with it?

Here is a part of my code:

\documentclass[a4paper,11pt,twoside]{report}
\begin{document}
    \begin{table}[h] 
    \caption[text} 
    \label{Tsomething} 
    \centering

    \renewcommand\arraystretch{2} 
    \resizebox{\textwidth}{!}
    {% \begin{tabular}{@{}|c|p{15cm}|p{15cm}|c|@{}} 
    \toprule 
    \textbf{Resource} & \textbf{Type} & \textbf{Application} & \textbf{Comment} \\
    \midrule 
    bla. & bla & bla &  \\ 
    \midrule 
    bla. & bla & bla & \\ 
    \midrule 
    bla. & bla & bla & \\ 
    \midrule 
    bla. & bla & bla & \\ 
    \midrule 
    bla. & bla & bla &  \\ 
    \midrule 
    bla. & bla & bla & \\ 
    \midrule bla. & bla & bla & \\ 
    \midrule bla. & bla & bla & \\ 
    \bottomrule \end{tabular}% } 
    \end{table}
 \end{document}  

I have some long sentences in the table, and i want latex to put these in several lines, instead of minimizing the font size to put it all in the same line. This is why i dont use the following code (then i can barely see the text).

\documentclass[a4paper,11pt,twoside]{report}
\begin{document}
    \begin{table}[h] 
    \caption[text} 
    \label{Tsomething} 
    \centering

    \renewcommand\arraystretch{2} 
    \resizebox{\textwidth}{!}
    {% \begin{tabular}{@{}|c|c|c|c|@{}} 
    \toprule 
    \textbf{Resource} & \textbf{Type} & \textbf{Application} & \textbf{Comment} \\
    \midrule 
    bla. & bla & bla &  \\ 
    \midrule 
    bla. & bla & bla & \\ 
    \midrule 
    bla. & bla & bla & \\ 
    \midrule 
    bla. & bla & bla & \\ 
    \midrule 
    bla. & bla & bla &  \\ 
    \midrule 
    bla. & bla & bla & \\ 
    \midrule bla. & bla & bla & \\ 
    \midrule bla. & bla & bla & \\ 
    \bottomrule \end{tabular}% } 
    \end{table}
 \end{document}   

Thank you for any help.

Answer 1

you might looking for the following result:

table width is equal to text width, font size is \small, widths of the second and third columns are equal and determined automatically by package `tabular

\documentclass[a4paper,11pt,twoside]{report}
\usepackage{ragged2e}
\usepackage{booktabs, tabularx}
\newcolumntype{L}{>{\RaggedRight}X}
\usepackage[skip=1ex]{caption}

\usepackage{lipsum}% for dummy text

\begin{document}
    \begin{table}[htb]
\caption{text}
\label{Tsomething}
    \centering
    \small
    \renewcommand\arraystretch{1.2}
\begin{tabularx}{\linewidth}{@{}c L L c@{}}
    \toprule
\textbf{Resource}
    & \textbf{Type}
        & \textbf{Application}
            & \textbf{Comment}  \\ 
    \midrule
bla.    & \lipsum[1][1-3] & \lipsum[1][1-3] &       \\ 
bla.    & bla           & bla   &       \\ 
bla.    & bla           & bla   &       \\ 
bla.    & bla           & bla   &       \\ 
bla.    & bla           & bla   &       \\ 
bla.    & bla           & bla   &       \\ 
bla.    & bla           & bla   &       \\ 
bla.    & bla           & bla   &       \\
    \bottomrule
\end{tabularx}
    \end{table}
\end{document}
