Table: Grouping table head not respecting nzWidthConfig

[Endran]

Reproduction link

https://2nl1sk.run.stackblitz.io

Steps to reproduce

Open stackblitz, or just go to the official docs https://ng.ant.design/components/table/en#components-table-demo-grouping-columns.
As you can see the Grouped table head is misaligned with the content, and there is some whitespace to the right and bottom of the component.

What is expected?

A perfectly aligned table head

What is actually happening?

Not aligned table head, instead some whitespace is present right and bottom

Environment	Info
ng-zorro-antd	8.0.3
Browser	Chrome 75, Safari 12.1.1

It works fine in Firefox 68

Let me also add a screenshot, straight from the docs.

this bug will happen when set automatically based on input device in macos

[Endran]

I do not understand what you mean with automatically based on input device. Is there something we need to do? I guess it needs fixing, since it is an regression compared to the Angular7 version.
