👑 [需求] EditableProTable 需要支持单个Cell的编辑功能。

### 🔩 所属模块或组件

EditableProTable

### 🥰 需求描述

editable 需要支持下标控制，用户双击或单击了哪个cell然后再显示哪个可编辑的组件。目前使用：
`onCell: (record) => ({
onDoubleClick: () => {
setEditableRowKeys([record.key]);
},
}), `

这样整个行都会处于编辑状态。

Start with the EditableProTable entry point and its editable configuration, then inspect how the onCell callback and editableRowKeys example currently activate editing. The change is done when a single cell selected by click or double-click shows its editable component without putting the whole row into edit mode.
