You will need to do a combination of steps.  You will need to build a jquery statement that upon selection of the checkbox, makes the read only field editable.  You will not select readonly in Laserfiche.  It would need to be a combo statement where upon document load, all fields are read only, unless the box is checked. 

You will need to name all your fields in the table with a css name.

$(document).ready(function () {
  $('.column1 input').prop("readonly",true);
  $('.column2 input').prop("readonly",true);
$('.cf-table-block tbody').on('click','.revise input:checked', undo);
      function undo() {
      $(this).each(function () {
        var column1 = $(this).closest('tr').find('.column1 input');
        var column2 = $(this).closest('tr').find('.column2 input');
        column1.prop("readonly",false);
        column2.prop("readonly",false);

 })
     }
});

If you are tracking changes, you will need an additional multi value SQL table (audit table) that would store all the previous changes, including the user updating and datetime of update, linking back to the unique id of that other table storing the info, that stores the old or incorrect changes and update the previous note column and current table with the corrections via workflow.
