Table column resize without table properties

Paste into the console:

editor.setData('<h3>Center aligned table</h3><figure class="table" style="width:87.27%;"><table><colgroup><col style="width:57.18%;"><col style="width:42.82%;"></colgroup><tbody><tr><td>foo</td><td>bar</td></tr><tr><td>&nbsp;</td><td>&nbsp;</td></tr></tbody></table></figure>')
