dataIndex

antd 4x

antd 4x， dataIndex，从对象格式，修改为 数组格式

const colIndex = 1;
const rowIndex = 2;
const columns = [
  {
    title: '姓名',
    dataIndex: 'name',
    key: 'name',
  },
  {
    title: '年龄',
    dataIndex: 'age',
    key: 'age',
  },
  {
    title: '住址',
    dataIndex: ['address', colIndex, rowIndex],
    key: 'address',
  },
  {
    title: '标签',
    dataIndex: ['tags',1],
    key: 'tags',
  },
];

巧用 dataIndex处理表格，二维数据

const dataSource = [
  {
    key: '1',
    name: '胡彦斌',
    age: 32,
    address: '西湖区湖底公园1号',
    tags: ['nice', 'developer'],
  },
  {
    key: '2',
    name: '胡彦祖',
    age: 42,
    address: '西湖区湖底公园1号',
    tags: ['cool', 'teacher'],
  },
];
const columns = [
  {
    title: '姓名',
    dataIndex: 'name',
    key: 'name',
  },
  {
    title: '年龄',
    dataIndex: 'age',
    key: 'age',
  },
  {
    title: '住址',
    dataIndex: 'address',
    key: 'address',
  },
  {
    title: '标签',
    dataIndex: 'tags[1]',
    key: 'tags',
  },
];

如果name是个对象， name: {firstname: ‘Eagle’, lastname: ‘Luo’}
将dataIndex 改为 name.firstname 或 name.lastname来获取下一层级的数据
如果使用了唯一的 dataIndex，那么我们就不再需要给每个 column加上 key了
