How can I support my antd design table to have drag and drop?

I want my users to be able to reorder the rows in a table by dragging and dropping

Hi @BlackBearFTW. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To support drag-and-drop functionality in an Ant Design table using the refine framework, you can utilize the useDrag and useDrop hooks from the react-dnd library. Below are the steps to achieve this: 1. Install react-dnd and react-dnd-html5-backend:

   npm install react-dnd react-dnd-html5-backend

   npm install react-dnd react-dnd-html5-backend

2. Create a Draggable Row Component: Define a component that will represent each row in the table and make it draggable using the useDrag hook.

   import React from "react";
   import { useDrag } from "react-dnd";
   import { Table } from "antd";

   const DraggableRow = ({ index, moveRow, className, style, ...restProps }) => {
       const [{ isDragging }, drag] = useDrag({
           type: 'row',
           item: { index },
           collect: (monitor) => ({
               isDragging: monitor.isDragging(),
           }),
       });

       return (
           <tr
               ref={drag}
               style={{ opacity: isDragging ? 0.5 : 1, cursor: 'move', ...style }}
               {...restProps}
           />
       );
   };

   export default DraggableRow;

   import React from "react";
   import { useDrag } from "react-dnd";
   import { Table } from "antd";

   const DraggableRow = ({ index, moveRow, className, style, ...restProps }) => {
       const [{ isDragging }, drag] = useDrag({
           type: 'row',
           item: { index },
           collect: (monitor) => ({
               isDragging: monitor.isDragging(),
           }),
       });

       return (
           <tr
               ref={drag}
               style={{ opacity: isDragging ? 0.5 : 1, cursor: 'move', ...style }}
               {...restProps}
           />
       );
   };

   export default DraggableRow;

3. Create a Droppable Table Component: Define a component that will represent the table and handle the drop logic using the useDrop hook.

   import React from "react";
   import { useDrop } from "react-dnd";
   import { Table } from "antd";
   import DraggableRow from "./DraggableRow";

   const DraggableTable = ({ dataSource, columns, onRowMove }) => {
       const moveRow = (dragIndex, hoverIndex) => {
           const dragRow = dataSource[dragIndex];
           const newData = [...dataSource];
           newData.splice(dragIndex, 1);
           newData.splice(hoverIndex, 0, dragRow);
           onRowMove(newData);
       };
const [, drop] = useDrop({
           accept: 'row',
           hover: (item, monitor) => {
               const dragIndex = item.index;
               const hoverIndex = monitor.getItem().index;

               if (dragIndex === hoverIndex) {
                   return;
               }

               moveRow(dragIndex, hoverIndex);
               item.index = hoverIndex;
           },
       });

       return (
           <Table
               ref={drop}
               dataSource={dataSource}
               columns={columns}
               components={{
                   body: {
                       row: DraggableRow,
                   },
               }}
           />
       );
   };

   export default DraggableTable;

   import React from "react";
   import { useDrop } from "react-dnd";
   import { Table } from "antd";
   import DraggableRow from "./DraggableRow";

   const DraggableTable = ({ dataSource, columns, onRowMove }) => {
       const moveRow = (dragIndex, hoverIndex) => {
           const dragRow = dataSource[dragIndex];
           const newData = [...dataSource];
           newData.splice(dragIndex, 1);
           newData.splice(hoverIndex, 0, dragRow);
           onRowMove(newData);
       };
const [, drop] = useDrop({
           accept: 'row',
           hover: (item, monitor) => {
               const dragIndex = item.index;
               const hoverIndex = monitor.getItem().index;

               if (dragIndex === hoverIndex) {
                   return;
               }

               moveRow(dragIndex, hoverIndex);
               item.index = hoverIndex;
           },
       });

       return (
           <Table
               ref={drop}
               dataSource={dataSource}
               columns={columns}
               components={{
                   body: {
                       row: DraggableRow,
                   },
               }}
           />
       );
   };

   export default DraggableTable;

4. Use the Draggable Table Component: Finally, use the DraggableTable component in your application. ```jsx import React, { useState } from "react"; import { DndProvider } from "react-dnd"; import { HTML5Backend } from "react-dnd-html5-backend"; import DraggableTable from "./DraggableTable"; const App = () => { const [data, setData] = useState([ { key: '1', name: 'John Brown', age: 32 }, { key: '2', name: 'Jim Green', age: 42 }, { key: '3', name: 'Joe Black', age: 32 }, ]); const columns = [ { title: 'Name', dataIndex: 'name', key: 'name' }, { title: 'Age ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
