Description
- I have searched the issues of this repository and believe that this is not a duplicate.
Reproduction link
Steps to reproduce
- open the codesandbox demo in a new window
- open the react dev tools profiler tab, check Record why each component rendered while profiling.
- start the react dev tools profiling
- check one record in the demo table
- stop the react dev tools profiling
- in the flamegraph, one can see every single checkbox is re-rendered with reasons saying: "Props changed: (onClick, onChange)"

What is expected?
Only the relative checkbox should be re-rendered.
What is actually happening?
All checkboxes are re-rendered.
| Environment | Info |
|---|---|
| antd | 4.12.3 |
| React | 17.0.1 |
| System | Windows 10 Pro 20H2 19042.804 |
| Browser | Microsoft Edge 88.0.705.74 |
There will be a noticeable UI lagging when there are hundreds of records in a table. onClick and onChange shouldn't be updated in each render.
