import { EditableProTable } from '@ant-design/pro-table'; import React, { useState } from 'react'; const defaultData: any = new Array(3).fill(1).map((_, index) => { return { id: (Date.now() + index).toString(), title: `活动名称${index}`, decs: '这个活动真好玩', state: 'open', created_at: '2020-05-26T09:42:56Z', }; }); export default () => { const [editableKeys, setEditableRowKeys] = useState<React.Key[]>(() => defaultData.map((item) => item.id), ); const [dataSource, setDataSource] = useState<any[]>(() => defaultData); const columns: any = [ { title: '活动名称', dataIndex: 'title', width: '30%', formItemProps: { rules: [ { required: true, whitespace: true, message: '此项是必填项', }, { message: '必须包含数字', pattern: /[0-9]/, }, { max: 16, whitespace: true, message: '最长为 16 位', }, { min: 6, whitespace: true, message: '最小为 6 位', }, ], }, }, { title: '状态', key: 'state', dataIndex: 'state', valueType: 'select', valueEnum: { all: { text: '全部', status: 'Default' }, open: { text: '未解决', status: 'Error', }, closed: { text: '已解决', status: 'Success', }, }, }, { title: '描述', dataIndex: 'decs', }, { title: '操作', valueType: 'option', width: 250, render: () => { return null; }, }, ]; return ( <> <EditableProTable<any> headerTitle="可编辑表格" columns={columns} rowKey="id" scroll={{ x: 960, }} value={dataSource} onChange={setDataSource} recordCreatorProps={{ newRecordType: 'dataSource', position: 'bottom', record: () => ({ id: Date.now(), }), }} editable={{ type: 'multiple', editableKeys, actionRender: (row, config, defaultDoms) => { return [defaultDoms.delete, <EditableProTable.RecordCreator parentKey={row.id} newRecordType='dataSource' position='bottom' record={{ id: Date.now(), }} > <a>增加子行</a> </EditableProTable.RecordCreator>]; }, onValuesChange: (record, recordList) => { setDataSource(recordList); }, onChange: setEditableRowKeys, }} /> </> ); };
三、解决方案
自己写一个递归的方法将子行追加到选中行下即可,下面展示的是我项目中的代码,不能复制直接用,但思路是一样的。
首先在actionRender
中自定义“增加子行”的操作按钮,其中addChildToSource
为增加逻辑方法:
actionRender: (row, _, dom) => [ <a key="addChild" onClick={() => addChildToSource(row.id, type)} > 增加子行 </a> ],
addChildToSource代码如下:
//增加子行 const addChildToSource = (rowKey: any, type: string) => { let childRowKey = Date.now(); //rowkey的id不能重复,不然会回填异常 editableKeys[type].push(childRowKey); let source = formRef.current.getFieldValue(`${type}_source`); //type_source为表格定义的formItem的name source = addChildToSourceFunc(source, rowKey, childRowKey, type); const _dict = {}; _dict[`${type}_source`] = source; formRef.current.setFieldsValue(_dict); setEditableKeys({ ...editableKeys }); };
上述方法调用的addChildToSourceFunc代码如下:
//删除参数edit及子级edit const addChildToSourceFunc = ( source: any, rowKey: any, childRowKey: any, type: string, childName: any = null, ) => { for (var i = 0; i < source.length; i++) { const sourceItem = source[i]; if (sourceItem.id === rowKey) { if (!sourceItem.children) { sourceItem.children = []; } sourceItem.children.push({ id: childRowKey, required: true, param_type: 'string', name: childName }); break; } else if (sourceItem.children) { addChildToSourceFunc(sourceItem.children, rowKey, childRowKey, type, childName,); } } return source; };
成功解决了该问题,解决后的效果:
