LaTeX: vertical alignment in a table containing a list

Question

In LaTeX, I use a package listingsto display a piece of code inside a table. But it seems that when using this package, the vertical alignment of the cells changes.

Here is the code:

\documentclass[a4paper,11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern,textcomp}
\usepackage[frenchb]{babel}
\usepackage{listings}

\begin{document}
\begin{tabular}{ll}
\hline Méthode & Exemple d'utilisation\\
\hline isLetter()&
\begin{lstlisting}
QChar MyChar('x');
bool IsLetter = MyChar.isLetter();
// IsLetter vaut vrai
// bla bla bla
\end{lstlisting}\\
\hline
\end{tabular}
\end{document}

and here is what I get (note the centered vertical alignment of the first column):

If I do not use the package listingsinside the table, the vertical alignment is different (in the center):

\begin{tabular}{lp{5cm}}
\hline Méthode & Exemple d'utilisation\\
\hline isLetter()&
QChar MyChar('x');
bool IsLetter = MyChar.isLetter();
// IsLetter vaut vrai
// bla bla bla
\\
\hline
\end{tabular}

I would like to add code inside the table, but keep the vertical alignment at the top for the cells.

, boxpos.

\begin{lstlisting}[boxpos=t]
QChar MyChar('x');
bool IsLetter = MyChar.isLetter();
// IsLetter vaut vrai
// bla bla bla
\end{lstlisting}

\parbox[t]{3cm}{Hello\\World\\Peace}
\parbox[t]{3cm}{Goodbye}

t, .
