react 和 antd  之 rowKey 问题

Warning: Each child in a list should have a unique "key" prop.

Check the render method of `Body`. See https://fb.me/react-warning-keys for more information.

解决办法:  [  :rowKey ] 

<!--id为 tableData 中的一个属性 -->
<Table dataSource={this.state.tableData} columns={columns} rowKey={record => record.id} />;
<Table dataSource={this.state.tableData} columns={columns} rowKey={columns => columns.id} />;
<Table dataSource={this.state.tableData} columns={columns} rowKey="id" />;
