[Tex/LaTex] adding notes below the table

tables

I want to add a note below the table. I referred the following link: Add notes under the table. But the code given :

\documentclass{article}
\usepackage{booktabs,caption,fixltx2e}
\usepackage[flushleft]{threeparttable}
\begin{document}

\begin{table}
  \begin{threeparttable}
    \caption{Sample ANOVA table}
     \begin{tabular}{lllll}
      \toprule
        Stubhead & \( df \) & \( f \) & \( \eta \) & \( p \) \          \midrule
        & \multicolumn{4}{c}{Spanning text} \            Row 1 & 1 & 0.67 & 0.55 & 0.41 \            Row 2 & 2 & 0.02 & 0.01 & 0.39 \            Row 3 & 3 & 0.15 & 0.33 & 0.34 \            Row 4 & 4 & 1.00 & 0.76 & 0.54 \          \bottomrule
    \end{tabular}
    \begin{tablenotes}
      \small
      \item This is where authors provide additional information about
      the data, including whatever notes are needed.
    \end{tablenotes}
  \end{threeparttable}
\end{table}
\end{document}

doesn't work(it doesn't compile and gives me 42 errors). I want to achieve a table something like this:
