Answer 1

This is exactly as it should be (compare in your browser).

Reason: You place span elements in the tbody. Only tr elements (and text nodes containing whitespace characters) are expected in there.

This is what I get in Firefox when I paste your HTML code:

So everything is as it should be - these spans are not "inserted" they are rather moved to an appropriate position.
