Nope, that wasn't the problem. When I remove the quotes the text changes but the table get's shifted as well, it makes the TD twice the size when the h5 works.
And that is an HTML problem ... it's what happens when you
stick a heading inside of a table cell. Besides, it is not
wise to try and control cell heights ... the height
attribute for <td> tags is deprecated
(reference).
You really should start using
Cascading Style Sheets if you
need that kind of control (and most of the time ... you
really don't).
