By removing lines "width: 100%;" for tables in core.css, tables with width attribute edited by ezoe output the width specified by ezoe. Currently, table width edited graphically on ezoe is neglected, which confuses beginners of eZ Publish using default tables because how tables look on editor may not appear so in resulting sites.

The table classes with width="100%" are
table.list, table.cols, table.renderedtable, table.comparison in /extension/ezwebin/design/ezwebin/stylesheets/core.css
table.list in /design/base/stylesheets/core.css
table.list, table.special in /design/admin/stylesheets/core.css
table.list, table.special in /design/standard/stylesheets/core.css
