  var row = footer.insertRow(0);
  var cell = row.insertCell(0);
  cell.innerHTML = "<b>This is a table footer</b>";
}
</script>

</body>
</html>

The createTFoot() method creates an empty <tfoot> element and adds it to the table.

If a <tfoot> element exists on the table, the createTFoot() method returns the existing one, and does not create a new one.

The <tfoot> element must have one or more <tr> tags inside.

The createTFoot() method returns the newly created or an existing <tfoot> element.
