// [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];

		table_html = table_html.replace(/<tr>(.*?)<t([hd])/gis, "<tr>$1<t$2 flag=1");
		table_html = table_html.replace(/flag=1 colspan/gis, "colspan");

		find = "(<t[hd] flag=" + (i-1) + ")(.*?)<t([hd])";
		p = new RegExp(find, "gis");
		table_html = table_html.replace(p, "$1$2<t$3 flag=" + i);
	}
