Using yckart's answer, I made it to search for the whole table - all td's.
$("#search").keyup(function() {
var value = this.value;
$("table").find("tr").each(function(index) {
if (index === 0) return;
var if_td_has = false; //boolean value to track if td had the entered key
$(this).find('td').each(function () {
if_td_has = if_td_has || $(this).text().indexOf(value) !== -1; //Check if td's text matches key and then use OR to check it for all td's
});
$(this).toggle(if_td_has);
});
});
