Как вариант:

<style type="text/css">
td {border: 1px black solid;}
</style>

<script type="text/javascript">
window.onload = function () {
    var container = document.getElementById('container');
    //Create TABLE
    var tagTable = document.createElement('TABLE');
    var attributetagTable = tagTable.setAttribute('class', 'table');
    var table = container.appendChild(tagTable);

    for (i = 0; i < 7; i++) {
        //Create TR
        var tagTr = document.createElement('TR');
        tagTr.setAttribute('class', 'tr');
        tagTable.appendChild(tagTr);

        //Create TD
        for (j = 0; j < 7; j++) {
            var tagTd = document.createElement('TD');
            tagTd.setAttribute('class', 'td');
            tagTd.innerHTML = j;
            tagTr.appendChild(tagTd);
        }
    }
}
</script>


<div id="container"></div>
