Adding multiple data to a column in react-table

I have a table using react-table but for one of the columns I want to show two pieces of data - name and description.

getInitialState(){
    return {
      data: [{
        id: 1,
        keyword: 'Example Keyword',
        product: [
          name: 'Red Shoe',
          description: 'This is a red shoe.'
        ]
      },{
        id: 2,
        keyword: 'Second Example Keyword',
        product: [
          name: 'blue shirt',
          description: 'This is a blue shirt.'
        ]
      }]
    }
},
render(){
  const { data } = this.state;

  return (
    <div className="app-body">
      <ReactTable
        data={data}
        columns={[{
          columns: [{
              Header: 'Id',
              accessor: id,
              show: false
            }, {
              Header: 'Keyword',
              accessor: 'keyword'
            }, {
              Header: 'Product',
              accessor: 'product'  // <<< here 
            }]
        }]}
      defaultPageSize={10}
      className="-highlight"
    />
    </div>
  )
}

Where the accessor is Product I want to show both the name and description (I'll style them to stack with different font sizes) in the Product column.

I've tried using the Cell: row => attribute for that column and thought I could also try calling a function that lays it out, but I've gotten errors both times.

Any ideas how to do this?

Indeed you should use Cell for this like this:

getInitialState(){
  return {
    data: [
      {
        id: 1,
        keyword: 'Example Keyword',
        product: [
          name: 'Red Shoe',
    description: 'This is a red shoe.'
]
},{
    id: 2,
      keyword: 'Second Example Keyword',
      product: [
      name: 'blue shirt',
      description: 'This is a blue shirt.'
  ]
  }]
}
},
render(){
  const { data } = this.state;

  return (
    <div className="app-body">
      <ReactTable
        data={data}
        columns={[{
          columns: [{
            Header: 'Id',
            accessor: id,
            show: false
          }, {
            Header: 'Keyword',
            accessor: 'keyword'
          }, {
            Header: 'Product',
            accessor: 'product',
            Cell: ({row}) => { //spread the props
              return (
                <div>
                  <span className="class-for-name">{row.product.name}</span>
                  <span className="class-for-description">{row.product.description}</span>
                </div>
              )
            }
          }]
        }]}
        defaultPageSize={10}
        className="-highlight"
      />
    </div>

  )
}

Another thing I spotted was that product property should be an object not an array, so change this:

product: [
          name: 'blue shirt',
          description: 'This is a blue shirt.'
        ]

to this:

product: {
          name: 'blue shirt',
          description: 'This is a blue shirt.'
        }
