i have problem with my live search the filtering is working but i want is only the <td> tags can filter and the <th> is not belong.

this is my html

and the javascript

function filter(element) {
    var $trs = $('.AvailableGroupLab tr').hide();
    var regexp = new RegExp($(element).val(), 'i');

    var $valid = $trs.filter(function () {
        return regexp.test($(this).find('td:first-child').text())
    }).show();

    $trs.not($valid).hide()
}

$('input').on('keyup change', function () {
    filter(this);
})

Try this:

function filter(element) {
var $trs = $('.AvailableGroupLab tr').not(":first").hide(); //don't hide first tr 
var regexp = new RegExp($(element).val(), 'i');

var $valid = $trs.filter(function () {
    return regexp.test($(this).find('td:first-child').text())
}).show();

$trs.not($valid).hide()
}

$('input').on('keyup change', function () {
    filter(this);
})
