[Tex/LaTex] How to i insert a big table in IEEE template

ieee-styletables

I am using IEEE template for my paper writing. Now i want to insert a table which is 11×12. So it needs to stretch to the two columns format in the IEEE format. I did like this:

\documentclass[conference]{IEEEtran}
\setlength{\extrarowheight}{1pt}
\begin{table}
 \caption{CIFAR-10 Confusion Matrix}
\label{my-label}
\begin{tabular}{|*{12}{p{1.11cm}|}}
\hline
labels     & airplane & automobile & bird & cat & deer & dog & frog & horse & ship & truck & accuracy \\ \hline
airplane   & 915      & 4          & 17   & 19  & 3    & 1   & 0    & 2     & 27   & 12    & 91.50\%  \\ \hline
automobile & 8        & 934        & 3    & 4   & 0    & 0   & 3    & 0     & 10   & 38    & 93.40\%  \\ \hline
bird       & 60       & 1          & 813  & 37  & 19   & 23  & 30   & 10    & 7    & 0     & 81.30\%  \\ \hline
cat        & 18       & 1          & 34   & 746 & 25   & 113 & 37   & 18    & 8    & 0     & 74.60\%  \\ \hline
deer       & 24       & 1          & 38   & 33  & 809  & 19  & 44   & 29    & 2    & 1     & 80.90\%  \\ \hline
dog        & 4        & 0          & 37   & 106 & 23   & 792 & 9    & 26    & 2    & 1     & 79.20\%  \\ \hline
frog       & 2        & 5          & 19   & 35  & 1    & 20  & 912  & 2     & 3    & 1     & 91.20\%  \\ \hline
horse      & 14       & 0          & 26   & 20  & 18   & 28  & 4    & 886   & 3    & 1     & 88.60\%  \\ \hline
ship       & 35       & 10         & 3    & 2   & 0    & 2   & 1    & 0     & 936  & 11    & 93.60\%  \\ \hline
truck      & 23       & 37         & 4    & 10  & 1    & 2   & 2    & 0     & 15   & 906   & 90.60\%  \\ \hline
\end{tabular}
\end{table}

and the output is:

The problem is that the caption is not centering between the two columns. How to do that??

How to center the table automatically between the two columns of IEEE format??

You need to use a table* environment instead of a table environment, to allow the float to take up the space of both columns.

In addition, you need to do something to reduce the width of the table. I suggest you use a tabularx environment instead of the tabular environment and that you use a centered version of the X column type for columns 2 thru 11. Use an l column type for the first column and a c column type for the final column. (If you really want to left-align all cell contents, use the X column type for columns 2 thru 11.)

Oh, and to try to give your table a more "open" look, say, by getting rid of all vertical lines and most horizontal lines and by generating well-spaced horizontal rules with the help of the booktabs package.

\documentclass[conference]{IEEEtran}
\usepackage{tabularx,booktabs}
\newcolumntype{C}{>{\centering\arraybackslash}X} % centered version of "X" type
\setlength{\extrarowheight}{1pt}

What I eventually did was using the IEEE tran template with the following code. Looks clean and saves space.

\author{
\IEEEauthorblockN{{\bf John Doe}\IEEEauthorrefmark{1}\IEEEauthorrefmark{2}\IEEEauthorrefmark{3}\\ \tt\footnotesize john@domain.com} \and
\IEEEauthorblockN{{\bf Jane Doe}\IEEEauthorrefmark{1}\\ \tt\footnotesize jane@domain.com}
\and
\IEEEauthorblockA{\IEEEauthorrefmark{1}Affiliate 1, Adress ...}
\IEEEauthorblockA{\IEEEauthorrefmark{2}Affiliate 2, Adress ...}
\IEEEauthorblockA{\IEEEauthorrefmark{3}Affiliate 3, Adress ...}
}

[Tex/LaTex] Avoid vertical white space between paragraphs in IEEE template (IEEEtran.cls)

All of this is in the comments, but possibly hard to follow if you are not familiar already with the language.

Basically, TeX places some stretchy space, between paragraphs. It's stretchy because it's not a fixed amount: it can expand (a bit) or contract (a bit). This is the \parskip of which you will read in the comments.

When TeX breaks up a page, it tries to some extent to arrive at a break which will "work well". The ideal break would be one which left every page naturally the same length (nice and neat). But other things can intervene (like leaving odd lines on the next page, or one line on the previous page, and so forth). So it doesn't always work out.

When TeX can't break a page perfectly, it will do one of two things (no other choice is possible really): it will either end the page early, so that one page is shorter than the other, or expand the stretch space between paragraphs to make up the slack. The usual default (\flushbottom) is to try to line up the bottom parts of the page by putting space between paragraphs. Some would say this was a bad design decision, but that bird has flown, though the LaTeX 3 project has page breaking as a major topic.

What's happening here is that for some reason (and those in the know suspect it's because there's a big block, probably a float, that needs to go at the top of the next page), TeX isn't finding a good line break, so it is ending up with a short page, and it is then expanding that stretchy space (quite considerably stretchy, which is why people are talking about the values of \parskip in this class) to make the bottom lines align (to arrive at the fabled flush bottom).

The best ways to deal with this are either to track down the source of the problem (i.e. why it's having a hard time breaking the page nicely: probably a float or a heading) and rewrite the manuscript to eliminate it) or to tell TeX not to bother getting the bottom of pages to line up, using the apparently scatalogical but quite harmless command \raggedbottom. Unless you are aiming for double-sided printing and really care about the typographical niceties, that's probably the best thing to try. (Sometimes you can enlarge a page a bit too, using \enlargethispage, to solve such problems).

TL;DR TeX is putting this space in in order to get the bottom lines of the pages to line up exactly because it's not able to find a clean page break. Either adjust your text to help it break cleanly, or tell it not to bother lining up the bottom of the page. Practical tip: solve this kind of problem last, when the whole manuscript is otherwise complete, because it's a waste of time making adjustments which may have to change later.
