TypeError in Table._adjustBodyCells() due to array index out of bounds

See original GitHub issue

Expected Behavior

State transitions caused by click on anchors/buttons defined in table body work as expected and no errors are logged.

Actual Behavior

Browser console logs: TypeError: Cannot read property ‘innerText’ of undefined and clicking on any anchor defined in table body does not cause state transition anymore.

Sample code

class HelloWorldApp extends React.Component {

  constructor(props) {
    super(props);   
    this.state = { showLayer: false, item: undefined};
  }
  
  _onClickEditItem(item) {
    this.setState({showLayer: true, item: item})
  }

  _onSort(idx, asc) {
    console.log('onSort');
  }

  render() {
    const items = [{
      name: 'My Test Item1',
      shortName: 'test1',
      description: 'bla fasel bum'
    }, {
      name: 'My Test Item2',
      shortName: 'test2',
      description: 'Lorem isum ...'
    }, {
      name: 'My Test Item3',
      shortName: 'test3',
      description: 'foo bar baz'
    }, ];
    const sortIndex = 1,
      sortAscending = true;
    const headerLabels = [
      <FormattedMessage id="name" />,
      <FormattedMessage id="shortName" />,
      <FormattedMessage id="desc" />,
    ];
    
    let child = null;
    if(this.state.showLayer && this.state.item){
      child = <Layer modal={true}><h2>{this.state.item.name}</h2></Layer>
    }
    return (
      <App>
        <Title>Hello World</Title>
        <Table>
            <TableHeader labels={headerLabels} sortIndex={sortIndex} sortAscending={sortAscending} onSort={this._onSort} />
          <tbody>
            { items.map(item => {
              return             <TableRow key={item.shortName}>
        <td><Anchor onClick={() => this._onClickEditItem(item)}>{item.name}</Anchor></td>
        <td>{item.shortName}</td>
        <td>{item.description}</td>
      </TableRow>

            })}
          </tbody>
        </Table>
        {child}
      </App>
    );
  }
};
