Place table footnotes and legend

footnotestables

I'm trying to reproduce the following table in latex:

enter image description here

But I can't put the table footnotes under the table. I would also like to add who is the author of the table below, as is done in the figures.

enter image description here

\begin{table}[htb!]
\setlength\tabcolsep{0pt}
%\small % <-- optional
\caption{Correntes de \textit{inrush} para diferentes conexões do transformador}
\begin{tabular*}{\textwidth}{@{\extracolsep{\fill}} cccccc }

\multicolumn{2}{c}{Banco de} &

\end{table}

I'm using the following compiler: pt.overleaf.com/latex/templates/pcall-tcc/dywydszxydqd. And the document class is abntex2

I'd like to suggest you employ machinery of the threeparttable package. Use \tnote{...} directives -- where ... could be \textasteriskcentered, \textdagger, or \textdagggerdbl -- inside the tabular environment to plant footnote markers. Then, use a tablenotes environment with \item[...] directives to typeset the corresponding footnote texts.

No special machinery seems to be needed for the Source attribution; see the code below for an implementation of this claim.
