Bootstrap's tooltip moves table cells to right a bit on hover

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="">
 &nbsp;
</td>

You can set the "data-container" at this way:

// initalize boostrap tooltip
    $(function () {
        $('[data-toggle="tooltip"]').tooltip({
            container: 'body'
        })
    })
