react 表格扩展与编辑

// 引入 Component 组件
import React, { Component } from ‘react‘;

//定义子表显示
const EditableContext = React.createContext();
const EditableRow = ({ form, index, ...props }) => (
  <EditableContext.Provider value={form}>
    <tr {...props} />
  </EditableContext.Provider>
);

const EditableFormRow = Form.create()(EditableRow);
class EditableCell extends React.Component {
  getInput = () => {
    // 这里也可以通过其他值判断显示下拉框（比如dataIndex）
    if (this.props.inputType === ‘number‘) {
      return <InputNumber />;
    }
    return <Input />;
  };

  render() {
    const {
      editing,
      dataIndex,
      title,
      inputType,
      record,
      index,
      ...restProps
    } = this.props;
    return (
      <EditableContext.Consumer>
        {(form) => {
          const { getFieldDecorator } = form;
          return (
            <td {...restProps}>
              {editing ? (
                <FormItem style={{ margin: 0 }}>
                  {getFieldDecorator(dataIndex, {
                    rules: [{
                      required: true,

                  })(this.getInput())}
                </FormItem>
