React-Table column fixed width spoils whole table

Question

Can someone explain this to me why i cant set fixed width on First Name column?It's setting passed width but it spoils whole table.If you tinker with resizing(by mouse) the column other columns will appear.Is this due to flebox?Im not familiar with flexbox.

var ReactTable = ReactTable.default
class App extends React.Component {
  constructor() {
    super();
    this.state = {
      data: []
    };
  }
  render() {
    const { data } = this.state;
    return (
      <div>
        <ReactTable
          data={data}
          columns={[
            {
              Header: "Name",
              columns: [
                {
                  width:'50',
                  Header: "First Name",
                  accessor: "firstName"
                },
                {
                  Header: "Last Name",
                  id: "lastName",
                  accessor: d => d.lastName
                }
              ]
            },
            {
              Header: "Info",
              columns: [
                {
                  Header: "Age",
                  accessor: "age"
                },
                {
                  Header: "Status",
                  accessor: "status"
                }
              ]
            },
            {
              Header: 'Stats',
              columns: [
                {
                  Header: "Visits",
                  accessor: "visits"
                }
              ]
            }
          ]}
          defaultPageSize={10}
          className="-striped -highlight"
        />
        <br />

      </div>
    );
  }
}

ReactDOM.render(<App />, document.getElementById("app"));

I don't know much about react-table, but try to not use quotes

var ReactTable = ReactTable.default
class App extends React.Component {
  constructor() {
    super();
    this.state = {
      data: []
    };
  }
  render() {
    const { data } = this.state;
    return (
      <div>
        <ReactTable
          data={data}
          columns={[
            {
              Header: "Name",
              columns: [
                {
                  Header: "First Name",
                  accessor: "firstName",
                  width: 50
                },
                {
                  Header: "Last Name",
                  id: "lastName",
                  accessor: d => d.lastName
                }
              ]
            },
            {
              Header: "Info",
              columns: [
                {
                  Header: "Age",
                  accessor: "age"
                },
                {

I don't know much about react-table, but you can solve this by setting width to all the columns.

var ReactTable = ReactTable.default
class App extends React.Component {
  constructor() {
    super();
    this.state = {
      data: []
    };
  }
  render() {
    const { data } = this.state;
    return (
      <div>
        <ReactTable
          data={data}
          columns={[
            {
              Header: "Name",
              columns: [
                {
                  width:'50',
                  Header: "First Name",
                  accessor: "firstName"
                },
                {
                  width:'100',
                  Header: "Last Name",
                  id: "lastName",
                  accessor: d => d.lastName
                }
              ]
            },
            {
              Header: "Info",
              columns: [
                {
                  width:'100',
                  Header: "Age",
                  accessor: "age"
                },
                {
                  width:'100',
                  Header: "Status",
                  accessor: "status"
                }
              ]
            },
            {
              Header: 'Stats',
              columns: [
                {
                  width:'100',
                  Header: "Visits",
                  accessor: "visits"
                }
              ]
            }
          ]}
          defaultPageSize={10}
          className="-striped -highlight"
        />
        <br />

      </div>
