Not sure what you mean. Here, it looks fine on both Firefox and Chrome, except that the second colum size could be smaller. If this is what you're meaning this can be fixed by changing the second line from: [width="100%",cols="2,1,10a",options="header",frame="none", grid="none"] to: [width="100%",cols="3,1,30a",options="header",frame="none", grid="none"] With regards to ReStructured Text, I've no idea how to control the format of a table in order to do things like hiding the borders and changing the column spacing. So, at least on a first glance, asciidoc seems to fit better.
