ant design中如何使用拖放?
How to use drag and drop in ant design?
我想要的是关于如何使我的 Table 的拖放操作正常工作的示例,但我不知道如何使其在(功能组件)
我的代码:
function Preview() {
const { name } = useParams();
const [fieldsOfForm, setFieldsOfForm] = useState([]);
const [selectedForm, setSelectedForm] = useState([]);
const columns = [
{
title: 'Posição',
dataIndex: 'pos',
width: 30,
className: 'drag-visible',
render: () =>
<MenuOutlined style={{ cursor: 'grab', color: '#999' }}/>
},
{
title: "Form Name",
dataIndex: "field",
key: "field",
render: (text) => <a>{text}</a>,
},
{
title: "Tipo",
dataIndex: "fieldtype",
key: "fieldtype",
},
];
useEffect(() => {
let mounted = true;
let loadingStates = loading;
if (mounted) {
setFieldsOfForm(location.state);
loadingStates.allFields = false;
setLoading(false);
}
return () => (mounted = false);
}, [selectedForm]);
return (
//Some jsx....
<Row gutter={1}>
<Col span={1}></Col>
<Table dataSource={fieldsOfForm}
columns= {columns}/>
</Row>
// More jsx...
);
}
export default Preview;
我在互联网上找到的关于从 antd 库拖放的所有内容都在 class component 中,但我想让它在我的功能中工作。
我找到的例子:
multi row drag-able table (antd)
如果有人已经尝试过并且可以帮助我,我想要功能组件中的一些示例?
这是一个实用的工作示例:

tempDataSource = merge(tempDataSource, filteredItems, newIndex);
}
setDataSource(tempDataSource);
setSelectedItems([]);
}
};
const DraggableContainer = (props) => (
<SortableContainer
useDragHandle
disableAutoscroll

);
const DraggableBodyRow = ({ className, style, ...restProps }) => {

const index = dataSource.findIndex(

? selectedItems.splice(selectedItems.indexOf(index), 1)
: selectedItems.push(index);
setSelectedItems(selectedItems);
} else {
setSelectedItems([]);
}
}}
/>
);
};
return (
<>
<h3>"CNTRL + Click" to select multiple items</h3>
<Table

}
