If you won't to access updated values you should listen to edit event.

I am using the example provided in the Inputs example section of https://mdbootstrap.com/docs/standard/plugins/table-editor:

const advancedColumns = [ { width: 250, label: "Company", field: "company", }, { width: 250, sort: false, defaultValue: "Warsaw", options: ["London", "Warsaw", "New York"], inputType: "select", label: "Office", field: "office", }, { width: 250, inputType: "number", defaultValue: 1, label: "Employees", field: "employees", }, { width: 100, defaultValue: false, inputType: "checkbox", label: "International", field: "international", }, ];

const advancedRows = [
  {
    company: "Smith & Johnson",
    office: "London",
    employees: 30,
    international: true,
  },
  {
    company: "P.J. Company",
    office: "London",
    employees: 80,
    international: false,
  },
  {
    company: "Food & Wine",
    office: "London",
    employees: 12,
    international: false,
  },
  {
    company: "IT Service",
    office: "London",
    employees: 17,
    international: false,
  },
  {
    company: "A. Jonson Gallery",
    office: "London",
    employees: 4,
    international: false,
  },
  {
    company: "F.A. Architects",
    office: "London",
    employees: 4,
    international: false,
  },
];

const tableDisableEdit = new TableEditor(
  document.getElementById("table_inputs"),
  { columns: advancedColumns, rows: advancedRows },
  { entries: 5, entriesOptions: [5, 10, 15] }
);
const tableEditor = document.getElementById("table_inputs");
tableEditor.addEventListener("add.mdb.tableEditor", (e) => {
  console.log(e.row);
});   </script>

The message sent in console.log always has the option defined by 'defaultValue' in the 'Office' option.
