                   $("table tr td:first-child").each(
                       function(){
                           if($(this).html() != a){
                               $(this).parent().hide();
                           }
                           else{
                               $(this).parent().show();
                           }
                       });
               });

$("#gender").on("change",

I made a simple script with jQuery (you have to include the jquery library).

HTML:

<select name="username" class="form-control selectpicker">
    <option value="">Username</option>
    <option value="">user1</option>
    <option value="">user2</option>
    <option value="">user3</option>
</select>

<select name="gender" class="form-control selectpicker">
    <option value="">Gender</option>
    <option value="">M</option>
    <option value="">F</option>

</select>
</div>

<table id="tbl" class="dynamicTable tableTools table table-striped table-primary">
    <!-- Table heading -->
        <thead>
            <tr>
                <th>Username</th>
                <th>Name</th>
                <th>Gender</th>
            </tr>
        </thead>

    <tbody>
        <tr>
            <td>user1</td>
            <td>Jane</td>
            <td>F</td>
        </tr>
        <tr>
            <td>user2</td>
            <td>John</td>
            <td>M</td>
        </tr>
        <tr>
            <td>user3</td>
            <td>Jack</td>
            <td>M</td>
        </tr>

    </tbody>
    <!-- // Table body END -->
</table>
<!-- // Table END -->

Javascript (jQuery):

$(document).ready(function() {
    function calculate() {
        $('#tbl tbody tr').show();
        var sel_username = $('select[name="username"] option:selected').text();
        var sel_gender = $('select[name="gender"] option:selected').text();

        if(sel_username == 'Username' && sel_gender == 'Gender') {
            return;
        }

        $('#tbl tbody tr').each(function() {
            var col_username = $(this).find('td').first();
            var col_gender = $(this).find('td').last();

            if(col_username.text() !== sel_username && sel_username !== 'Username') {
                $(this).hide();
            }

            if(col_gender.text() !== sel_gender && sel_gender !== 'Gender') {
                if($(this).is(':visible')) {
                    $(this).hide();
                }
            }
        });
    }

    $('select[name="username"]').change(function() {
        calculate();
    });

    $('select[name="gender"]').change(function() {
        calculate();
    });
});
