I am using Bootstrap 3.1.1 for my project. Each cell in my table contains data like 000 or 111. On hover, I want to display this data as a tooltip. So          
        
You can set the "data-container" at this way:
// initalize boostrap tooltip
    $(function () {
        $('[data-toggle="tooltip"]').tooltip({
            container: 'body'
        })
    })
                                                                        You have to add the data-container="body" as per documentation.
<td data-original-title="999" data-container="body"
 data-toggle="tooltip" data-placement="bottom" title="">
  
</td>
