// [http://hyperpolyglot.org] is a wonderfull website which provides contrast of programming languages. Sometimes the table contains languages that you don't care about, you can use this script to delete them, just modify the $columnscnt and $delcolumns vars, and run it from the console.
// how many columns does the table have;
var columnscnt = 5;
// which columns do you what to delete;
var delcolumns = [2, 5];
var find, p, seq, i;
var table_ele = document.getElementsByClassName("wiki-content-table")[0];
var table_html = table_ele.innerHTML;
table_html = table_html.replace('/colspan="5"/g', 'colspan="3"');
for (i = 1; i < columnscnt+1; i++) {
if (i === 1) {
table_html = table_html.replace(/<tr>(.*?)<t([hd])/gis, "<tr>$1<t$2 flag=1");
