Title: Eliminating extra td elements in thead with 'left' or 'right' options

Suppose that I have a table with two rows in thead. As far as I know, one suggested practice in this case is to use td elements in one row, like:

```

1
2
3

Name1
Name2
Name3

Fixing the left or right two columns, for example, would be accomplished with:
new FixedHeader(table, {"left": 2});
new FixedHeader(table, {"right": 2});

Unfortunately, FixedHeader fails to remove the extra td elements in this case. The fix seems to be straightforward.
