latex, floating tables side by side?

hedpe · 10-29-2006, 09:54 AM

Hey guys,

I am trying to float two tables to the top of the page to span across both columns of an IEEE journal style paper, so I did doing this:

Code:

\begin{figure*}
\centering
\label{fig:sdevalarms}
  \begin{tabular}{|l|c|c|c|c|c|}
    \hline    
              & D\_IN   & D\_OUT  & R\_ADDR & PORT    & FSD     \\
    \hline
    D\_IN     &   -     & 83.67\% & 73.47\% & 75.51\% & 18.37\% \\
    \hline
    D\_OUT    & 56.16\% &   -     & 67.12\% & 65.75\% & 17.80\% \\
    \hline
    R\_ADDR   & 52.17\% & 71.01\% &   -     & 91.30\% & 18.84\% \\
    \hline
    PORT      & 55.22\% & 71.64\% & 94.03\% &   -     & 16.42\% \\
    \hline
    FSD       & 20.00\% & 28.89\% & 28.89\% & 24.44\% &   -     \\
    \hline
  \end{tabular}

  \begin{tabular}{|l|c|c|c|c|c|}
    \hline    
              & D\_IN   & D\_OUT  & R\_ADDR & PORT    & FSD     \\
    \hline
    D\_IN     &   -     & 78.95\% & 62.11\% & 65.26\% & 29.47\% \\
    \hline
    D\_OUT    & 39.47\% &   -     & 37.89\% & 38.95\% & 17.89\% \\
    \hline
    R\_ADDR   & 52.68\% & 64.29\% &   -     & 86.61\% & 46.43\% \\
    \hline
    PORT      & 55.86\% & 66.67\% & 87.39\% &   -     & 40.54\% \\
    \hline
    FSD       & 33.73\% & 40.96\% & 62.65\% & 54.22\% &   -     \\
    \hline
  \end{tabular}
\caption{Wavelet based anomaly detection}
\end{figure*}

Except, doing that floats them, but they are directly on top of each other. I'd like them to be side by side with about an inches worth of space between them.

Any ideas?

Thanks!
George

You should probably use a longtable environment to achieve fancy effects with tables instead of using a floating environment.

One idea is instead of having two separate tables, try and achieve the same visual effect by using a single table with columns to hold both the tables.

got it, thanks for the suggestion:

Code:

\begin{table*}[htbp]
\label{table:alarms}
\centering
  \begin{minipage}{8.5cm}
  \begin{tabular}{|l|c|c|c|c|c|}
    \hline    
              & D\_IN   & D\_OUT  & R\_ADDR & PORT    & FSD     \\
    \hline
    D\_IN     &   -     & 83.67\% & 73.47\% & 75.51\% & 18.37\% \\
    \hline
    D\_OUT    & 56.16\% &   -     & 67.12\% & 65.75\% & 17.80\% \\
    \hline
    R\_ADDR   & 52.17\% & 71.01\% &   -     & 91.30\% & 18.84\% \\
    \hline
    PORT      & 55.22\% & 71.64\% & 94.03\% &   -     & 16.42\% \\
    \hline
    FSD       & 20.00\% & 28.89\% & 28.89\% & 24.44\% &   -     \\
    \hline
  \end{tabular}

  \end{minipage}
  \begin{minipage}{8.5cm}

    \hline
    D\_OUT    & 39.47\% &   -     & 37.89\% & 38.95\% & 17.89\% \\
    \hline
    R\_ADDR   & 52.68\% & 64.29\% &   -     & 86.61\% & 46.43\% \\

\end{table*}

Glad you got it.

I would still prefer the longtable solution over using floats. To me using the longtable environment is cleaner for more complex tabular presentation.
