Reproduction link

Steps to reproduce

The reproduction demo was based on the official demo
https://ant.design/components/table/#components-table-demo-custom-filter-panel
Check on the reproduction link, click on the search button on the right side of the searchable column header, write sth in the input element inside of the dropdown search panel, then click on the other area to close the dropdown search panel.

What is expected?

Expect not to trigger the onChange event of pagination. At least exposed an API for developers to stop this auto-trigger behavior.

What is actually happening?

When you click the search button on the right side of the searchable column header, write sth in the input element inside of the dropdown search panel, then click on the other area to close the dropdown search panel. You'll find the onChange event of pagination was triggered.
