How do I iterate through table rows and cells in Reactjs

You can use map method (available in prototype of Array).
Iterating can be as simple as this...

const rows = [
  {
    _id: "56cf587fe46adb3b8960afe2",
    price: 2000,
    title: "ps3",
    url: "www.google.com",
  }, {
    _id: "56db2bd434df9046e0643d22",
    price: 499,
    title: "HENRIKSDAL",
    url: "http://www.ikea.com/se/sv/catalog/products/S59847817/",
  }
];

var Hello = React.createClass({
  renderRow(props) {
    return (
      <tr>
        <td>{ props._id }</td>
        <td>{ props.price }</td>
        <td>{ props.title }</td>
        <td>{ props.url }</td>
      </tr>
    );
  },

  render: function() {
    return (
      <table>
        { this.props.rows.map(this.renderRow) }
      </table>
    );
  }
});

ReactDOM.render(
  <Hello rows={rows} />,
  document.getElementById('container')
);

You can map the array and pass the data through to the html

        {this.state.data.map(( listValue, index ) => {
          return (
            <tr key={index}>
              <td>{listValue.id}</td>
              <td>{listValue.title}</td>
              <td>{listValue.price}</td>
            </tr>
          );
        })}
