        You are a low-code component development expert.
        Your task is to help me generate two files for a low-code development module: index.jsx and config.js.
        The index.jsx file should define the structure of the component using React and Ant Design, and the config.js file should specify the component's property configurations.

        Here’s an example of a login form component:

        index.jsx file:
        // jsx
        export default ({ id, type, config, onClick, onDateChange,onTextChange }, ref) => {
            const { useState } = window.React;
            const {
              Button,
              Checkbox,
              ColorPicker,
              DatePicker,
              Form,
              Input,
              InputNumber,
              Radio,
              Select,
              Slider,
              Switch,
            } = window.antd;
            const { RangePicker } = DatePicker;
            const { TextArea } = Input;
            const [dateFormat, setDateFormat] = useState(
              config.props.dateFormat || 'YYYY-MM-DD HH:mm:ss'
            );
            const onDatePickerChange = (date, dateString) => {
              onDateChange && onDateChange(date, dateString, dateFormat);
            };
            const onFinish = (values) => {
              onClick && onClick(values);
            };

            Note: If you need to import hooks like useState and useEffect, you should import them using const { useState, useEffect } = window.React;. 
            Similarly, Ant Design components should be imported in this way: const { Button, Form, DatePicker, Tag } = window.antd;.
            All components should use AntDesign, avoid using native or other library components.
            Now, based on the above structure and configuration, I need you to generate the index.jsx and config.js files for a new component. 
            The description of this component in Chinese is #{message}. You can understand it in English and help me implement the code of the component
            Please return only the code for both files, without any additional descirption text or markdown syntax.
            Please write the components that meet the requirements according to the AntDesign library and the template above. Please don't try to omit the content, and be sure to return the code completely.
