Please read the HTML specifications for an explaination. By my reading
border="2" is in fact invalid in html5:

The border attribute may be specified on a table element to
explicitly indicate that the table element is not being used for
layout purposes. If specified, the attribute's value must either
be the empty string or the value "1". The attribute is used by
certain user agents as an indication that borders should be drawn
around cells of the table.

In html4 it does seem to do the same thing:

border = pixels [CN]
This attributes specifies the width (in pixels only) of the frame
around a table (see the Note below for more information about this
attribute).

Use css selectors. If you want to set the style attribute directly on
the table element in a post-processor you may, but is is not
considered best practice.
