问 题

错误：

代码如下：

import { Table, Input, Icon, Button, Popconfirm } from 'antd';

class EditableCell extends React.Component {
  state = {
    value: this.props.value,
    editable: false,
  }
  handleChange = (e) => {
    const value = e.target.value;
    this.setState({ value });
  }
  check = () => {
    this.setState({ editable: false });
    if (this.props.onChange) {
      this.props.onChange(this.state.value);
    }
  }
  edit = () => {
    this.setState({ editable: true });
  }
  render() {
    const { value, editable } = this.state;
    return (<div className="editable-cell">
      {
        editable ?
        <div className="editable-cell-input-wrapper">
          <Input
            value={value}
            onChange={this.handleChange}
            onPressEnter={this.check}
          />
          <Icon
            type="check"
            className="editable-cell-icon-check"
            onClick={this.check}
          />
        </div>
        :
        <div className="editable-cell-text-wrapper">
          {value || ' '}
          <Icon
            type="edit"
            className="editable-cell-icon"
            onClick={this.edit}
          />
        </div>
      }
    </div>);
  }
}

class EditableTable extends React.Component {
  constructor(props) {
    super(props);
    this.columns = [{
      title: 'name',
      dataIndex: 'name',
      width: '30%',
      render: (text, record, index) => (
        <EditableCell
          value={text}
          onChange={this.onCellChange(index, 'name')}
        />
      ),
    }, {
      title: 'age',
      dataIndex: 'age',
    }, {
      title: 'address',
      dataIndex: 'address',
    }, {
      title: 'operation',
      dataIndex: 'operation',
      render: (text, record, index) => {
        return (
          this.state.dataSource.length > 1 ?
          (
            <Popconfirm title="Sure to delete?" onConfirm={this.onDelete(index)}>
              <a href="#">Delete</a>
            </Popconfirm>
          ) : null
        );
      },
    }];

    this.state = {
      dataSource: [{
        key: '0',
        name: 'Edward King 0',
        age: '32',
        address: 'London, Park Lane no. 0',
      }, {
        key: '1',
        name: 'Edward King 1',
        age: '32',
        address: 'London, Park Lane no. 1',
      }],
      count: 2,
    };
  }
  onCellChange = (index, key) => {
    return (value) => {
      const dataSource = [...this.state.dataSource];
      dataSource[index][key] = value;
      this.setState({ dataSource });
    };
  }
  onDelete = (index) => {
    return () => {
      const dataSource = [...this.state.dataSource];
      dataSource.splice(index, 1);
      this.setState({ dataSource });
    };
  }
  handleAdd = () => {
    const { count, dataSource } = this.state;
    const newData = {
      key: count,
      name: `Edward King ${count}`,
      age: 32,
      address: `London, Park Lane no. ${count}`,
    };
    this.setState({
      dataSource: [...dataSource, newData],
      count: count + 1,
    });
  }
  render() {
    const { dataSource } = this.state;
    const columns = this.columns;
    return (<div>
      <Button className="editable-add-btn" type="ghost" onClick={this.handleAdd}>Add</Button>
      <Table bordered dataSource={dataSource} columns={columns} />
    </div>);
  }
}

ReactDOM.render(<EditableTable />, mountNode);
.editable-cell {
  position: relative;
}

.editable-cell-input-wrapper,
.editable-cell-text-wrapper {
  padding-right: 24px;
}

.editable-cell-text-wrapper {
  padding: 5px 24px 5px 5px;
}

.editable-cell-icon,
.editable-cell-icon-check {
  position: absolute;
  right: 0;
  width: 20px;
  cursor: pointer;
}

.editable-cell-icon {
  line-height: 18px;
  display: none;
}

.editable-cell-icon-check {
  line-height: 28px;
}

.editable-cell:hover .editable-cell-icon {
  display: inline-block;
}

.editable-cell-icon:hover,
.editable-cell-icon-check:hover {
  color:#2db7f5;
}

.editable-add-btn {
  margin-bottom: 8px;
}

解决方案

import { Table, Input, Icon, Button, Popconfirm } from 'antd';

class EditableCell extends React.Component {
    constructor(props) {
        spuer(props);
        
        this.state = {
            value: props.value,
            editable: false,
        }
  }
  handleChange = (e) => {
// ...

state部分在构造函数声明。
