Ever tried to copy&paste a table from Wikipedia to your favourite spreadsheet software? You just want the pure data and not all those hyperlinks and embedded images? This script removes unnecessary stuff from the tables. Simply run in firebug console and

// remove all images
$('table img').remove();

// remove all reference links
$('table .reference').remove()

// convert all links to plain text
$('table a').each(function(index, el) { $(el).replaceWith($(el).html()) });
