Is it possible to make fields required on material-table

Question

I am working on a project, where I basically do crud using material-table interface. I am wondering is there a way if I can make fields required if I want too?

I tried researching but not much results. Please see the code below which is straight forward from https://material-ui.com/components/tables/ last example. Of course I have modified on my codebase for my personal use and everything works fine, but I am not sure how is it possible to make fields required if I want too? If yes, how would I do it? Would I pass something as a prop option on MaterialTable ?

Thank you for any suggestions.

import React from 'react';
import MaterialTable from 'material-table';

export default function MaterialTableDemo() {
  const [state, setState] = React.useState({
    columns: [
      { title: 'Name', field: 'name' },
      { title: 'Surname', field: 'surname' },
      { title: 'Birth Year', field: 'birthYear', type: 'numeric' },
      {
        title: 'Birth Place',
        field: 'birthCity',
        lookup: { 34: 'İstanbul', 63: 'Şanlıurfa' },
      },
    ],
    data: [
      { name: 'Mehmet', surname: 'Baran', birthYear: 1987, birthCity: 63 },
      {
        name: 'Zerya Betül',
        surname: 'Baran',
        birthYear: 2017,
        birthCity: 34,
      },
    ],
  });

  return (
    <MaterialTable
      title="Editable Example"
      columns={state.columns}
      data={state.data}
      editable={{
        onRowAdd: newData =>
          new Promise(resolve => {
            setTimeout(() => {
              resolve();
              const data = [...state.data];
              data.push(newData);
              setState({ ...state, data });
            }, 600);
          }),
        onRowUpdate: (newData, oldData) =>
          new Promise(resolve => {
            setTimeout(() => {
              resolve();
              const data = [...state.data];
              data[data.indexOf(oldData)] = newData;
              setState({ ...state, data });
            }, 600);
          }),
        onRowDelete: oldData =>
          new Promise(resolve => {
            setTimeout(() => {
              resolve();
              const data = [...state.data];
              data.splice(data.indexOf(oldData), 1);
              setState({ ...state, data });
            }, 600);
          }),
      }}
    />
  );
}

Material-table has native support for validation which can trivially be used to make a field required. All you have to do is specify the validation field in the columns specification as per docs here: https://material-table.com/#/docs/features/validation.

Here's what that would look like for your code, say if you wanted to make the "Surname" required:

...
  const [state, setState] = React.useState({
    columns: [
      { title: 'Name', field: 'name' },
      {
          title: 'Surname',
          field: 'surname',
          validate: rowData => Boolean(rowData.surname),
      },
      { title: 'Birth Year', field: 'birthYear', type: 'numeric' },
      {
        title: 'Birth Place',
        field: 'birthCity',
        lookup: { 34: 'İstanbul', 63: 'Şanlıurfa' },
      },
    ],
    data: [
      { name: 'Mehmet', surname: 'Baran', birthYear: 1987, birthCity: 63 },
      {
        name: 'Zerya Betül',
        surname: 'Baran',
        birthYear: 2017,
        birthCity: 34,
      },
    ],
  });
...

p.s. there's no need to put your columns data in the state here unless it's going to change, which seems unlikely in this case.
