rc-table with resize and scroll props lags between the header and the body

[ivanmontiel-lw]

• [X] I have searched the issues of this repository and believe that this is not a duplicate.
  • Note: I have seen a few similar issues with many rows and performance, but none specifically for resizing.

Reproduction link

Steps to reproduce

1. Use Ant Table (or the rc-table directly), with code to implement the column resize behavior and scroll y.
2. Try to resize the column
3. The more rows rendered, the more the problem is noticeable.

What is expected?

No performance issues. Header cell widths and row columns widths stay the same.

What is actually happening?

There is noticeable lag of the header cells and desync between header widths and row widths.

Environment	Info
antd	4.6.1
React	16.12.0
System	Mac OS X
Browser	Chrome 84.0.4147.125

---

From investigating, when the scroll y prop and column widths are updated, every row in the table is re-rendered when the column is resized.
