In this fiddle http://jsfiddle.net/jnddfyeq/ I have two tables with border-collapse: collapse
. In the first one everything works as expected. In the second one I position the caption
with position: absolute
and now the borders between the thead
and tbody
do not collapse.
This happens in Firefox 38 and IE8 (not in a fiddle.) I have not tested other browsers. Is this behavior standard? If so why?
UPDATE: Same thing happens in Safari.
