I found a few examples of adding an ID to a table row, however they do not seem to fit my needs based on my table script.

I tried row.add() but just could not figure out how to do this when using columns:[ ]

            childTable = $('#customerRows').DataTable({
                         
                dom: 't',
                ajax: { 
                           type: 'POST',
                           url: 'getSalepersonByCustomerBillTo_CustomerData.php',
                        data: {salespersonNumber: salespersonNumber},
                },
                pageLength:100,

                columns: [
                    {
                        className: 'detail-level-control_2',
                        orderable: false,
                        data: null,
                        defaultContent: '',
                    },
                    { 
                        data: 'customer'
                    },

                    {
                        data: null,
                        searchable: false,
                        orderable: false,
                        render: function ( data, type, row ) {
                            if (row.openBudget != 0) {

                                 return '<td><button id="openBudgetButton">Open '+ row.openBudget + '</button></td>';
                                  
                                   }else{
                                       
                                     return '<td><strong><p style="color:green;">Completed</p></strong></td>';
                                      
                                  }
                          }
                     },  

                     {
                         data: null,
                         searchable: false,
                         orderable: false,
                         render: function ( data, type, row ) {
                              
                              if (row.openBudget != 0) {

                                  return '<td><button id="completedBudgetButton">Completed '+ row.completedBudget + '</button></td>';
                                  
                                     }else{

                                  return '<td><button id="totalBudgetButton">Total '+ row.totalBudget + '</button></td>';
                                  
                                     }else{
                                         
                                         return '<td></td>';
