How to add space between table and page edge?

[Wibda]

I made the page and table in it in Wordpress.
The page style is "full width page".
The table i made has no spaces between left side and right side of page.
How can i add spaces?

<div style="align: center;">[spacer height="20px"]
<table id="center-table" style="height: 90%; width: 100%; border-collapse: collapse">

Why did you make the table's width 100%.You can also use css to adjust position and width adjustment.If you have no idea on css, go to tutorials point and download the pdf format of cds tutorial.
