How to make table in the center of whole page

Question

I'm new to Latex. The following is my latex code. The emnlp2017 package in the example can be downloaded from here.

% Author information can be set in various styles:

% if the names do not fit well on one line use
%         Author 1 \\ {\bf Author 2} \\ ... \\ {\bf Author n} \\
% For authors from different institutions:
% \author{Author 1 \\ Address line \\  ... \\ Address line
%         \And  ... \And

%         \AND
%         Author 2 \\ Address line \\ ... \\ Address line \And
%         Author 3 \\ Address line \\ ... \\ Address line}
% If the title and author information does not fit in the area allocated,
% place \setlength\titlebox{<new height>} right after
% at the top, where <new height> can be something larger than 2.25in

the result is

it is out of boundary right side, How to solve it? I want to make this table in the center of the whole page so that avoid overflow, how to make it?

Also, i want to add horizontal line separating mean and var from column "data" to the end, how to do it?

Thank you!

you need to make it fit on the page you have not said how big the page is so can not help much but putting \small before the tabular probably helps. — David Carlisle, Apr 06 '17 at 20:11
Welcome to TeX SX! The table is too wide. There are various solutions, but please post a minimal compilable code (including \documentclass). — Bernard, Apr 06 '17 at 20:11

the screenshot is the half of the whole page size @David Carlisle — Alex, Apr 06 '17 at 20:14
yes, it is a 2-column document but the table has 8 columns in total@Bernard — Alex, Apr 06 '17 at 20:22
emnlp2017 is the name of conference i gonna post to. the emnlp2017 package is forcibly included in the official template — Alex, Apr 06 '17 at 20:28
Where can we get it? With the standard article class, the table fits between the margins. — Bernard, Apr 06 '17 at 20:45

Off-topic: The subfigure package is deprecated and shouldn't be used. Use either the subfig or the subcaption package. — Mico, Apr 06 '17 at 21:22

Use the starred version of table* and add \cline{2-8} to make the separators.

If you want a table not necessarily at the top of the page, you can use the strip environment from cuted.

I simplified your table code for column heads, using the \thead command, from makecell. Also, note times is obsolete, as it does not have support for maths. So I replaced it with the newtx package, based on the Times clone TeX Gyre Termes. The subfigure package is obsolete too, and no more developed. I replaced it with the subcaption package, which defines a subfigure environment.

Last point, I gave a more professional look to your table, using the rules from booktabs and no vertical rules. I differentiated the mean and var rows using colour, instead of a separating rule.
