Alternating Background Color react-bootstrap-table

Question

I am using react-bootstrap-table and I am trying to alternate the background color. The documentation leaves it a bit unclear what type of data in particular goes into it's implementation of the conditional rendering function so I cannot receive the correct result. What am I doing wrong?

// Customization Function 
function rowClassNameFormat(row, rowIdx) {
  // row is whole row object
  // rowIdx is index of row
  return rowIdx % 2 === 0 ? 'backgroundColor: red' : 'backgroundColor: blue';
}

// Data
var products = [
  {
    id: '1',
    name: 'P1',
    price: '42'
  },
  {
    id: '2',
    name: 'P2',
    price: '42'
  },
  {
    id: '3',
    name: 'P3',
    price: '42'
  },
];

// Component
class TrClassStringTable extends React.Component {
  render() {
    return (
      <BootstrapTable data={ products } trClassName={this.rowClassNameFormat}>
          <TableHeaderColumn dataField='id' isKey={ true }>Product ID</TableHeaderColumn>
          <TableHeaderColumn dataField='name'>Product Name</TableHeaderColumn>
          <TableHeaderColumn dataField='price'>Product Price</TableHeaderColumn>
      </BootstrapTable>
    );
  }
}

You can customize the inline styles with trStyle instead of trClassName. The inlined styles should also be returned in object form, not as a string.

Example

function rowStyleFormat(row, rowIdx) {
  return { backgroundColor: rowIdx % 2 === 0 ? 'red' : 'blue' };
}

class TrClassStringTable extends React.Component {
  render() {
    return (
      <BootstrapTable data={ products } trStyle={rowStyleFormat}>
          <TableHeaderColumn dataField='id' isKey={ true }>Product ID</TableHeaderColumn>
          <TableHeaderColumn dataField='name'>Product Name</TableHeaderColumn>
          <TableHeaderColumn dataField='price'>Product Price</TableHeaderColumn>
      </BootstrapTable>
    );
  }
}
