How can I pass Array to React Table Component?

import React, { useMemo, useState, useEffect } from 'react';
import Table from './Table';
import './App.css';
import sampleJson from './sample.json';

function App() {
  const columns = React.useMemo(
    () => [
      {
        Header: 'Left Rail',
        columns: [
          {
            Header: 'Name',
            accessor: 'name',
          },
          {
            Header: 'Address',
            accessor: 'address',
          },
        ],
      },
      {
        Header: 'Right Rail',
        columns: [
          {
            Header: 'Date',
            accessor: 'date',
          },
          {
            Header: 'Order #',
            accessor: 'order',
          },
        ],
      },
    ],
    []
  );

  const [data, setData] = useState([]);

  const getData = () => {
    fetch(
      './data/json-data.json',
      //sampleJson
      {
        headers: {
          'Content-Type': 'application/json',
          Accept: 'application/json',
        },
      }
    )
      .then(function (response) {
        console.log(response);
        return response.json();
      })
      .then(function (myJson) {
        console.log(myJson);

        setData(myJson);
      });
  };

  useEffect(() => {
    getData();
  }, []);

  // return  !data.length ? (<div>Loading..</div>) : (
  return (
    <div className='App'>
      <Table columns={columns} data={data} />
    </div>
  );
}

export default App;
