[Tex/LaTex] Wrapping a text in a table’s cell in LateX

Question

I have a problem with wrapping the text in the table's cell when using tabular. The phrase in the cell goes beyond the text width. I tried to apply multirow command but it don't change a thing. Why? Well, I receive an error whenever using multirow that a curly bracket (}) is missing. I've looked it over and over again and can't see it. Maybe someone could just test it and offer a free of error lines.

\documentclass[12pt]{article}
\usepackage[english]{babel}

\usepackage{multirow}

\begin{table}[t]
\centering

 \begin{tabular}{lll}
 \hline

  \textbf{Name \& Author(s)} & \textbf{Label}  & \textbf{Definition}                                                                                      \\ \hline

              Poggi 2001     & Nod             & "a down-up movement of the head"                                                                                       \\

              Allwood 2003   & Nod            & "a forward movement of the head going up and down, which can be multiple"\\

This is the output that I get:

This looks like a good application for the tabularx package.

Please do not use " for quotation marks.

\documentclass[12pt]{article}
\usepackage[english]{babel}

\usepackage{tabularx}
\usepackage{booktabs}

\begin{document}

\begin{table}[t]
    \centering
    \begin{tabularx}{\textwidth}{@{}llX@{}}
        \toprule
        \textbf{Name \& Author(s)} & \textbf{Label}  & \textbf{Definition}\\
        \midrule
        Poggi 2001 & Nod & ``a down-up movement of the head''\\
        Allwood 2003 & Nod & ``a forward movement of the head going up and down, which can be multiple''\\
        \bottomrule
    \end{tabularx}
\end{table}

\end{document}
