I need to display a table with first row underlined. For that, I am setting border-collapse and setting border only for the first row. Its working fine in IE 7 and FF. But in IE 8(compatibility mode), the bottom border is broken. See this [fiddle][1]

Text1	Text2	Text3

Doctypes are never optional for new web pages. Transitional doctypes are for old, deprecated markup. Always use strict.
