How to add tables to a list?

Question

I would like to have these two tables as items of this list. Currently they are appearing outside the list, on the top of the page.

\documentclass[12pt, oneside]{article}

\usepackage[brazil]{babel}
\usepackage[latin1,utf8]{inputenc}
\usepackage{enumerate}

\begin{document}

%%%%%%%%% problem

  \begin{itemize}
    \item item1
    \item item2
    \begin{table}
    \parbox{.45\linewidth}{
    \centering
        \begin{tabular}{l|ll}
        + & 0 & 1 \\ \hline
        0 & 0 & 1 \\
        1 & 1 & 0 \\
        \end{tabular}
    \caption{adicao}
    }
    \hfill
    \parbox{.45\linewidth}{
    \centering
        \begin{tabular}{l|ll}
        . & 0 & 1 \\ \hline
        0 & 0 & 1 \\
        1 & 0 & 1 \\
        \end{tabular}
    \caption{mult}
    }
    \end{table}

  \end{itemize}
\end{document}

I have been searching about how to do it, however, until now I've only found how to do the opposite (how to insert lists in tables).

Answer 1

The problem is that the table environment is a float, and float placement is handled in a very particular way by LaTeX. You can use the package float, which gives a float placement option, H, that essentially causes the float to no longer be treated as a float.

^{(Shameless self promotion: see my answer to Is there any way to shift two \includegraphics images? Having trouble with \begin{figure} for a discussion about the different possible parameters for float placement in LaTeX.)}

\documentclass{article}

\usepackage[brazil]{babel}
\usepackage[latin1,utf8]{inputenc}
\usepackage{enumerate}

\usepackage{float}

\begin{document}

\begin{itemize}

    \item item 1

    \item item 2

        \begin{table}[H]
        \parbox{.45\linewidth}{
        \centering
        \begin{tabular}{l|ll}
        + & 0 & 1 \\ \hline
        0 & 0 & 1 \\
        1 & 1 & 0 \\
        \end{tabular}
        \caption{Adição}
        }
        \hfill
        \parbox{.45\linewidth}{
        \centering
        \begin{tabular}{l|ll}
        . & 0 & 1 \\ \hline
        0 & 0 & 1 \\
        1 & 0 & 1 \\
        \end{tabular}
        \caption{Multiplicação}
        }

        \end{table}

    \item item 3

\end{itemize}

\end{document}
