react+antdesign实现嵌套table,并且，点击父table的每一行，使得expandedRowRender只被渲染一次

好的，关于你的问题，我可以给出以下思路：
1. 在父table中，将每一行的onClick事件与expandedRowRender方法绑定，确保每次点击时只渲染一次。
2. 在expandedRowRender中，实现嵌套table的渲染，使用Ant Design中的Table组件。
3. 在子table中，按需渲染父table中每一行对应的数据。
希望这些思路能够帮助你解决问题。

帮我用react+antdesign实现一个表格嵌套两层表格的效果，以class MonitorList extends React.Component命名

好的，以下是一个简单的实现示例：

import React from 'react';
import { Table } from 'antd';

class MonitorList extends React.Component {
  state = {
    dataSource: [
      {
        key: '1',
        name: 'John Brown',
        age: 32,
        address: 'New York No. 1 Lake Park',
        children: [
          {
            key: '11',
            name: 'John Brown Jr.',
            age: 18,
            address: 'New York No. 2 Lake Park',
          },
          {
            key: '12',
            name: 'John Brown Sr.',
            age: 45,
            address: 'New York No. 3 Lake Park',
            children: [
              {
                key: '121',
                name: 'John Brown',
                age: 18,
                address: 'New York No. 3 Lake Park',
              },
              {
                key: '122',
                name: 'Mike Brown',
                age: 25,
                address: 'New York No. 4 Lake Park',
              },
            ],
          },
        ],
      },
      {
        key: '2',
        name: 'Jim Green',
        age: 42,
        address: 'London No. 1 Lake Park',
        children: [
          {
            key: '21',
            name: 'Jim Green Jr.',
            age: 18,
            address: 'London No. 2 Lake Park',
          },
          {
            key: '22',
            name: 'Jimmy Green Sr.',
            age: 45,
            address: 'London No. 3 Lake Park',
            children: [
              {
                key: '221',
                name: 'Jim Green',
                age: 18,
                address: 'London No. 3 Lake Park',
              },
              {
                key: '222',
                name: 'Jenny Green',
                age: 25,
                address: 'London No. 4 Lake Park',
              },
            ],
          },
        ],
      },
    ],
    columns: [
      {
        title: 'Name',
        dataIndex: 'name',
        key: 'name',
      },
      {
        title: 'Age',
        dataIndex: 'age',
        key: 'age',
      },
      {
        title: 'Address',
        dataIndex: 'address',
        key: 'address',
      },
    ],
  };

  render() {
    const { dataSource, columns } = this.state;

    const renderNestedTable = (record) => {
      const nestedColumns = [
        {
          title: 'Name',
          dataIndex: 'name',
          key: 'name',
        },
        {
          title: 'Age',
          dataIndex: 'age',
          key: 'age',
        },
        {
          title: 'Address',
          dataIndex: 'address',
          key: 'address',
        },
      ];

      return (
        <Table
          columns={nestedColumns}
          dataSource={record.children}
          pagination={false}
          size="small"
        />
      );
    };

    return (
      <Table
        columns={columns}
        dataSource={dataSource}
        expandedRowRender={renderNestedTable}
      />
    );
  }
}

export default MonitorList;

这个示例使用了Ant Design的Table组件实现了一个表格嵌套两层表格的效果。其中，外层表格的数据源为一个包含嵌套子数据的数组，内层表格的数据源则为嵌套子数据的`children`字段，通过在外层表格中设置`expandedRowRender`属性为一个函数，可以在每一行展开时自动渲染内层表格。

帮我用antdesign+react实现三个表格嵌套效果

好的，下面是一个简单的实现示例：

import React from "react";
import { Table } from "antd";

const columns1 = [
  {
    title: "姓名",
    dataIndex: "name",
    key: "name"
  },
  {
    title: "年龄",
    dataIndex: "age",
    key: "age"
  },
  {
    title: "住址",
    dataIndex: "address",
    key: "address"
  }
];

const columns2 = [
  {
    title: "学科",
    dataIndex: "subject",
    key: "subject"
  },
  {
    title: "分数",
    dataIndex: "score",
    key: "score"
  }
];

const columns3 = [
  {
    title: "项目",
    dataIndex: "project",
    key: "project"
  },
  {
    title: "进度",
    dataIndex: "progress",
    key: "progress"
  }
];

const data1 = [
  {
    key: "1",
    name: "张三",
    age: 18,
    address: "北京市朝阳区"
  },
  {
    key: "2",
    name: "李四",
    age: 20,
    address: "上海市浦东新区"
  }
];

const data2 = [
  {
    key: "1",
    subject: "数学",
    score: 90
  },
  {
    key: "2",
    subject: "语文",
    score: 95
  }
];

const data3 = [
  {
    key: "1",
    project: "设计",
    progress: "80%"
  },
  {
    key: "2",
    project: "开发",
    progress: "60%"
  }
];

class NestedTable extends React.Component {
  constructor(props) {
    super(props);

    this.state = {
      expandedRowKeys: []
    };
  }

  onExpand = (expanded, record) => {
    const { expandedRowKeys } = this.state;

    if (expanded) {
      this.setState({
        expandedRowKeys: [...expandedRowKeys, record.key]
      });
    } else {
      this.setState({
        expandedRowKeys: expandedRowKeys.filter(key => key !== record.key)
      });
    }
  };

  render() {
    const { expandedRowKeys } = this.state;

    const expandedRowRender1 = record => (
      <Table
        columns={columns2}
        dataSource={data2}
        pagination={false}
        size="small"
        showHeader={false}
      />
    );

    const expandedRowRender2 = record => (
      <Table
        columns={columns3}
        dataSource={data3}
        pagination={false}
        size="small"
        showHeader={false}
      />
    );

    return (
      <Table
        columns={columns1}
        dataSource={data1}
        pagination={false}
        size="small"
        expandedRowRender={expandedRowRender1}
        expandedRowKeys={expandedRowKeys}
        onExpand={this.onExpand}
        rowKey="key"
      >
        <Table
          columns={columns2}
          dataSource={data2}
          pagination={false}
          size="small"
          showHeader={false}
        />
        <Table
          columns={columns3}
          dataSource={data3}
          pagination={false}
          size="small"
          showHeader={false}
        />
      </Table>
    );
  }
}

export default NestedTable;

这个示例中，我们使用了三个表格分别表示三个不同的数据源，然后将它们嵌套在了一个表格中，通过 `expandedRowRender` 属性指定了第一个表格展开时应该渲染的内容，同时也提供了可以展开和收起的功能。
