Example page: http://musicbrainz.org/release-group/1b022e01-4da6-387b-8658-8678046e4cef musicbrainz.org/release-group/{mbid} template is including an extra th (only for logged in users). This causes the second, correct, th to have a +1 problem in the colspan count. There are only 9 columns, with the checkbox column included; the extra th gives a total defined th colspan of 10, which causes the table to be narrower than it needs to be in Chrome. (Chrome handles it per the W3C standard; Opera and Firefox both treat the "9" as if it were "8".) <tr class="subh"> <th></th> THIS SHOULDN'T BE HERE <th colspan="9">Official</th> </tr>
