Reproduction link

Steps to reproduce

1. Create a Table with expandable rows and log each time the expandedRowRender function is called.
2. Hover over the table rows and view the log output.

What is expected?

Only trigger the expandedRowRender function when the row is being expanded.

What is actually happening?

The expandedRowRender function is being triggered on every mouse movement inside the table.

While doing some more investigation about this issue. The problem seems to be introduced in the following commit: 2bb9407

The problem is introduced in rc-table version 7.19.0. When upgrading rc-table to 7.21.0 the problem seems to be fixed.

Still get the error re-render when update rc-table to 7.21.0 version. Any suggest for me pls

@tungphien use resolutions in your package.json file to temporarily upgrade the rc-table package to version 7.21.0 till they release a new ANTD version with the new rc-table version.

In your package.json add the following on root level.

"resolutions": {
    "antd/rc-table": "7.21.0"
}

Make sure to delete the resolution after upgrading to a new ANTD version.

@roelvdboom Any ideal

I down grade Antd version to solve this problem temporarily. In package.json: change to this: "antd": "~4.16.0",
