我试图将值从子组件表中的复选框传递到父组件

如此处建议： React: How to add an array of Ids to the state object from nested objects

我的代码是这样的：

内部组件：

import React, { Component } from 'react';
import {  Table, Radio} from 'antd';
import { adalApiFetch } from '../../adalConfig';
import Notification from '../../components/notification';

class ListPageTemplatesWithSelection extends Component {

    constructor(props) {
        super(props);
        this.state = {
            data: []
        };
    }

    fetchData = () => {
        adalApiFetch(fetch, "/PageTemplates", {})
          .then(response => response.json())
          .then(responseJson => {
            if (!this.isCancelled) {
                const results= responseJson.map(row => ({
                    key: row.Id,
                    Name: row.Name
                  }))
              this.setState({ data: results });
            }
          })
          .catch(error => {
            console.error(error);
          });
      };


    componentDidMount(){
        this.fetchData();
    }

    render(){
        const columns = [
                {
                    title: 'Id',
                    dataIndex: 'key',
                    key: 'key',
                }, 
                {
                    title: 'Name',
                    dataIndex: 'Name',
                    key: 'Name',
                }
        ];


        return (
            <Table rowSelection={() => this.props.onRowSelect(this.columns.Id)}  columns={columns} dataSource={this.state.data} />
        );
    }
}

export default ListPageTemplatesWithSelection;

父组件

const FormItem = Form.Item;

        this.handleChangeAlias = this.handleChangeAlias.bind(this);
        this.handleChangeDisplayName = this.handleChangeDisplayName.bind(this);

                  .then(response =>{
                    if(response.status === 201){
                        Notification(

                            'Site collection created',
                            ''

                        {

                            message: 'Please input your alias',
                        }
                    ]

                            required: true,
                            message: 'Please input your display name',
                        }
                    ]
                })(<Input name="displayname" id="displayname" onChange={this.handleChangeDisplayName} />)}
                </FormItem>
                <FormItem {...formItemLayout} label="Description" hasFeedback>

                        }
                    ],
                })(<Input name="description" id="description"  onChange={this.handleChangeDescription} />)}
                </FormItem>

                <ListPageTemplatesWithSelection onRowSelect={this.handleRowSelect} />

                <FormItem {...tailFormItemLayout}>
                    <Button type="primary" htmlType="submit">
                        Create modern site
                    </Button>
                </FormItem>
            </Form>
        );
    }
}

const WrappedCreateModernSiteCollectionForm = Form.create()(CreateModernSiteCollectionForm);
export default WrappedCreateModernSiteCollectionForm;

但是我在控制台中收到此错误

index.js:2177 Warning: Failed prop type: Invalid prop `rowSelection` of type `function` supplied to `Table`, expected `object`.
    in Table (at ListPageTemplatesWithSelection.js:53)

根据ANTD docs，rowSelection是一个对象，用作表的行选择行为的配置。在您的示例中，您似乎试图将选择处理程序传递给组件。因此，根据该对象的签名，您应该尝试做

    const rowSelection = {
        onSelect: () => this.props.onRowSelect(this.columns.Id)
    };

    <Table rowSelection={rowSelection} />

失败的道具类型：向“表”提供了“功能”类型的道具“ rowSelection”无效，预期是“对象”
