Update database table from a table of form data

I'm trying to update a database table from a table with a list of names with an additional column with a checkbox. The user is checking the box to indicate that someone in the list attended the event.

I'm loading the view in a table format with names and a column for the checkbox.

The problem I'm having is how to identify the row of each column without displaying the id for each name in the database. If I use a hidden column for the id... it doesn't get transfered.

I am able to pass the id by adding the id to the value on the checkbox but then it comes of as an array.

Here's the form:

<form id="eventpracnames" action="/events/updateeventnames" method="POST">
                                        {{ Method_field ('Patch')}}
                                        {{csrf_field()}}

                                        <div class="row justify-content-left">
                                                        <header id="EventsEditnameheader">
                                                                <table class="table table-striped " >
                                                                <thead>
                                                                        <tr>
                                                                                <th style="width: 25%;">First Name</th>
                                                                                <th style="width: 25%;">LastName</th>
                                                                                <th style="width: 29%;">Attended</th>
                                                                                
                                                                        </tr>
                                                                </thead>
                                                                </table>

                                        </div>

                                        <div class="form-row" style="width: 60%; margin-top:25px;">
                                              <input type="submit" class="btn btn-primary btn-lg" value="Save Changes">
                                        </div>
                                </form>

Any ideas would be appreciated. Thanks
