customize of autoref

Question

in this example, how can I customize \autoref. ie instead of printing table 1, it puts Tab.1 same question with Figure = Fig. and equation = Eq.

\documentclass{article}
\usepackage[T1]{fontenc}
%\usepackage[francais]{babel} 
\usepackage{graphicx}
\usepackage[font=footnotesize,labelfont={bf,sc,small},figurename=Fig.,tablename=Tab.]{caption}
\usepackage[colorlinks=true,linkcolor=blue]{hyperref} 

\begin{document}

change the writing of \autoref{tab} to Tab.1

\begin{table}[htbp]
\begin{center}
\begin{tabular}{|l|l|}
\hline
table & Tab. \\
\hline
figure & Fig. \\
\hline
equation & Eq. \\
\hline
\end{tabular}
\end{center}
\caption{Exemple d'environnement table}
\label{tab}
\end{table}

\end{document}

Answer 1

Voila:

\documentclass{article}
\usepackage[T1]{fontenc}
%\usepackage[francais]{babel} 
\usepackage{graphicx}
\usepackage[font=footnotesize,labelfont={bf,sc,small},figurename=Fig.,tablename=Tab.]{caption}
\usepackage[colorlinks=true,linkcolor=blue]{hyperref} 

\begin{document}

\renewcommand{\tableautorefname}{Tab.} % PS

change the writing of \autoref{tab} to Tab.1

\begin{table}[htbp]
\begin{center}
\begin{tabular}{|l|l|}
\hline
table & Tab. \\
\hline
figure & Fig. \\
\hline
equation & Eq. \\
\hline
\end{tabular}
\end{center}
\caption{Exemple d'environnement table}
\label{tab}
\end{table}

\end{document}

One should change not the meaning of \somethingname but \somethingautorefname. In this case it is \tableautorefname.
