first line indent of List of tables

Question

I need to add the word Figure and Table to list of tables and figures. I have the code below to obtain this but my code applies extra space to the first line of the text in the list of tables. All the lines should have no indent.

There are some answers about this topic but they are based on tocloft. I have a thesis format, so I need a solution without tocloft.

\documentclass{article}
\usepackage{lipsum}
\begin{document}
    \let\oldnumberline\numberline%
    \renewcommand{\numberline}{\hspace{-1.5em}Table~\oldnumberline}%
    \listoftables%

    \section{A section}

    \begin{table}[h]
        \begin{centering}
            \begin{tabular}{ccc}
                $T_1$ & $T_2$\\
                \hline 
                $75^\circ$ & $25^\circ$\\
            \end{tabular}
            \par\end{centering}
        \caption{\lipsum[4]\label{tab_ref}}       
    \end{table}
\end{document}

Answer 1

Maybe the following helps:

\documentclass{article}
\usepackage{lipsum}

\let\oldnumberline\numberline
\makeatletter
\renewcommand\l@table{\@dottedtocline{1}{0em}{4em}}
\makeatother

\begin{document}

\renewcommand{\numberline}[1]{\oldnumberline{Table #1}}
\listoftables

\section{A section}
\begin{table}[h]
  \centering
  \begin{tabular}{ccc}
    $T_1$ & $T_2$\\
    \hline 
    $75^\circ$ & $25^\circ$
  \end{tabular}
  \caption{\lipsum[4]\label{tab_ref}}
\end{table}
\end{document}
