React-table Select All Select Box

Question

https://codesandbox.io/s/8x331yomp0

I'm trying to create a select all checkbox in my table. When I click the header checkbox, I want the other checkboxes to populate, as well.

I'm trying to do this with a selectAlll state value, but for whatever reason, this keeps coming back false the first time, so it is always opposite of what the value should be. Any chance someone knows what is wrong? I put the code sandbox up at the top, but here is my table code:

import React, { Component } from "react";
import $ from "jquery";
import ReactTable from "react-table";
import "react-table/react-table.css";

const style = {
  container: {
    position: "relative"
  },

  refresh: {
    cursor: "pointer",
    width: "75px"
  }
};

class KKTable extends Component {
  constructor() {
    super();
    this.state = {
      loading: true,
      timestamp: "",
      selectAll: false,
      data: [],
      checked: []
    };
    this.handleChange = this.handleChange.bind(this);
  }

  handleChange = () => {
    var selectAll = !this.state.selectAll;
    this.setState({ selectAll: selectAll });
    var checkedCopy = [];
    this.state.data.forEach(function(e, index) {
      checkedCopy.push(selectAll);
    });
  };

  componentDidMount() {
    const data2 = [
      { one: "hi0", two: "two0", three: "three0" },
      { one: "hi1", two: "two1", three: "three1" },
      { one: "hi2", two: "two2", three: "three2" },
      { one: "hi3", two: "two3", three: "three3" },
      { one: "hi4", two: "two4", three: "three4" },
      { one: "hi5", two: "two5", three: "three5" },
      { one: "hi6", two: "two6", three: "three6" },
      { one: "hi7", two: "two7", three: "three7" },
      { one: "hi8", two: "two8", three: "three8" }
    ];

    var checkedCopy = [];
    var selectAll = this.state.selectAll;
    data2.forEach(function(e, index) {
      checkedCopy.push(selectAll);
    });

    this.setState({
      data: data2,
      checked: checkedCopy,
      selectAll: false
    });
  }

  render() {
    return (
      <div>
        <div className="container">
          <ReactTable
            data={this.state.data}
            filterable
            defaultFilterMethod={(filter, row) =>
              row[filter.id] !== undefined
                ? String(row[filter.id])
                    .toLowerCase()
                    .includes(filter.value.toLowerCase())
                : false
            }
            columns={[
              {
                Header: "One",
                accessor: "one"
              },
              {
                Header: <input type="checkbox" onChange={this.handleChange} />,
                Cell: row => (
                  <input
                    type="checkbox"
                    defaultChecked={this.state.checked[row.index]}
                  />
                ),
                sortable: false,
                filterable: false
              },
              {
                Header: "Two",
                accessor: "two"
              },
              {
                Header: "Three",
                accessor: "three"
              }
            ]}
            className="-striped "
          />
        </div>
      </div>
    );
  }
}

Figured it out. In case anyone needs the code:

import React, { Component } from "react";
import $ from "jquery";
import ReactTable from "react-table";
import "react-table/react-table.css";

const style = {
  container: {
    position: "relative"
  },

  refresh: {
    cursor: "pointer",
    width: "75px"
  }
};

class KKTable extends Component {
  constructor() {
    super();
    this.state = {
      loading: true,
      timestamp: "",
      selectAll: false,
      data: [],
      checked: []
    };
    this.handleChange = this.handleChange.bind(this);
    this.handleSingleCheckboxChange = this.handleSingleCheckboxChange.bind(
      this
    );
  }

  handleChange = () => {
    var selectAll = !this.state.selectAll;
    this.setState({ selectAll: selectAll });
    var checkedCopy = [];
    this.state.data.forEach(function(e, index) {
      checkedCopy.push(selectAll);
    });
    this.setState({
      checked: checkedCopy
    });
  };

  handleSingleCheckboxChange = index => {
    console.log(index);

    var checkedCopy = this.state.checked;
    checkedCopy[index] = !this.state.checked[index];
    if (checkedCopy[index] === false) {
      this.setState({ selectAll: false });
    }

    this.setState({
      checked: checkedCopy
    });
  };

  componentDidMount() {
    const data2 = [
      { one: "hi0", two: "two0", three: "three0" },
      { one: "hi1", two: "two1", three: "three1" },
      { one: "hi2", two: "two2", three: "three2" },
      { one: "hi3", two: "two3", three: "three3" },
      { one: "hi4", two: "two4", three: "three4" },
      { one: "hi5", two: "two5", three: "three5" },
      { one: "hi6", two: "two6", three: "three6" },
      { one: "hi7", two: "two7", three: "three7" },
      { one: "hi8", two: "two8", three: "three8" }
    ];

    var checkedCopy = [];
    var selectAll = this.state.selectAll;
    data2.forEach(function(e, index) {
      checkedCopy.push(selectAll);
    });

    this.setState({
      data: data2,
      checked: checkedCopy,
      selectAll: selectAll
    });
  }

  render() {
    console.log(this.state);
    return (
      <div>
        <div className="container">
