Checkbox checked per row only using JQuery in blade template

is it possible to checked only the checkbox which belongs to a row in a table inside blade template using jquery? i have this table view

i want to checked only the students belongs to 7-A without including the student in 7-B how do i make it work? i'm using for-each loop to display the data in my table. With my current jquery code it will check all the item inside the table.

View Table:

 <table class="table  table-hover table-bordered" > 

                <tr>
                <th>Section</th>
                <th>Student</th>

                </tr>


                @foreach($sections as $section)
                <tr>
                <td>  
                <input type="checkbox" id="chckHead" />
                <label>  <label>
                </td>
                <td>  
                @foreach($section->lead as $bt)
                <input type="checkbox" class="chcktbl"  name="lead_id[]" value="">
                      <label ></label>
                @endforeach
                </td>

                </tr>
                @endforeach

                </table>

Script

<script type="text/javascript">
$('#chckHead').click(function () {
    if (this.checked == false) {
        $('.chcktbl:checked').attr('checked', false);
    }
    else {
        $('.chcktbl:not(:checked)').attr('checked', true);
    }
});
$('#chckHead').click(function () {
});
