Wrap the non-header rows in <tbody></tbody>. Then use Array#prototype.reduce() to scan the rows in reverse, treating the first (ie last) row as a special case : $(“table tbody tr”).get().reverse().reduce(function(prevVal, tr, i) { var $tds = $(tr).find(‘td’), val = Number($tds.eq(1).text().replace(‘,’,”)) diff = val – prevVal; // console.log(val); $tds.eq(2).text((i > 0) ? diff : ‘-‘); $tds.eq(3).text((i > … Read more
