Float right is not working with my Wordpress Mantra theme

I need to place a table in the right corner of a page and text wrap around the table. I used the following codes.

.floater {
margin: 5px;
float: right;
}
.floater td {
padding: 2px;
border: 1px solid black;
}

---

<table class="floater">
*--- table---*
</table>
<p>text</p>

Here is the jsfiddle: http://ift.tt/1AfJJ8l It is working well with the all the editor and not working while updating in my website. I am using Wordpress Mantra Theme.
