I'm using the "nomobile" class which works fine in a surrounding <div class="nombile"> .. <.div>, but did not work in a table element, eg. <table align=center cellpadding=10 style="border-radius: 10px" class="nomobile">
Topic on Extension talk:MobileFrontend
Feel free to add a table.nomobile class in your MediaWiki:Mobile.css We are hoping to deprecate use of .nomobile in the far far future and provide better ways to style content differently on mobile/desktop.
