Note:
Depending on you Bootstrap version (prior to 3.3 or not), you may need a different answer.
Pay attention to the notes.

When I activate tooltips (hover over the cell) or popovers in this code, size of table is increasing. How can I avoid this?

Here emptyRow - function to generate tr with 100

<html>
<head>
    <title></title>
    <script type="text/javascript" language="javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
    <link type="text/css" rel="stylesheet" href="http://twitter.github.com/bootstrap/assets/css/bootstrap.css">
    <script type="text/javascript" language="javascript" src="http://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/2.2.1/bootstrap.min.js"></script>
    <style>    
    #matrix td {
        width: 10px;
        height: 10px;
        border: 1px solid gray; 
        padding: 0px; 
    }
    </style>
<script>
function emptyRow() {
        str = '<tr>'
        for (j = 0; j < 100; j++) {
            str += '<td rel="tooltip" data-original-title="text"></td>'
        }
        str += '</tr>'
        return str
    }
    $(document).ready(function () {
        $("#matrix tr:last").after(emptyRow())
        $("[rel=tooltip]").tooltip();
    });
    </script>
</head>
<body style="margin-top: 40px;">
<table id="matrix">
    <tr>
    </tr>
</table>
</body>
</html>

thank in advice!

Note: Solution for Bootstrap 3.0 ~ 3.2

You need to create an element inside a td and apply a tooltip to it, like this, because a tooltip itself is a div, and when it is placed after a td element it brakes table layout.

This problem was introduced with the latest release of Bootstrap. There are ongoing discussions about fixes on GitHub here. Hopefully the next version includes the fixed files.
