-|----|-------|-----------------------------------------|
-| 🚀 | 流程模型  | 配置工作流的流程模型，支持 BPMN 和仿钉钉/飞书设计器           |
-| 🚀 | 流程表单  | 拖动表单元素生成相应的工作流表单，覆盖 Element UI 所有的表单组件  |
-| 🚀 | 用户分组  | 自定义用户分组，可用于工作流的审批分组                     |
-| 🚀 | 我的流程  | 查看我发起的工作流程，支持新建、取消流程等操作，高亮流程图、审批时间线     |
-| 🚀 | 待办任务  | 查看自己【未】审批的工作任务，支持通过、不通过、转派、委派、退回、加减签等操作 |
-| 🚀 | 已办任务  | 查看自己【已】审批的工作任务，支持流程预测，展示未来审批人信息         |
-| 🚀 | OA 请假 | 作为业务自定义接入工作流的使用示例，只需创建请求对应的工作流程，即可进行审批  |

+| 会签         | 同一个审批节点设置多个人（如 A、B、C 三人，三人会同时收到待办任务），需全部同意之后，审批才可到下一审批节点                            | ✅    |
+| 或签         | 同一个审批节点设置多个人，任意一个人处理后，就能进入下一个节点                                                     | ✅    |
+| 依次审批       | （顺序会签）同一个审批节点设置多个人（如 A、B、C 三人），三人按顺序依次收到待办，即 A 先审批，A 提交后 B 才能审批，需全部同意之后，审批才可到下一审批节点 | ✅    |
+| 抄送         | 将审批结果通知给抄送人，同一个审批默认排重，不重复抄送给同一人                                                     | ✅    |
+| 驳回         | （退回）将审批重置发送给某节点，重新审批。可驳回至发起人、上一节点、任意节点                                              | ✅    |
