Of course they display "narrow" rows, as they simply will not render the CSS style, because you omitted to add a Doctype to your document, thus the document will be displayed in so called "quirks mode" (that means each browser will takes his own arbitrary course).
Doctype is a must:
Use, say, a HTML 4.01 strict Doctype. Now all the browsers will see the same thing. If you don't like how it looks like, change your CSS properties/values accordingly.
As a tip: you should set the height
and the line-height
CSS properties of the cells.
