Thanks for your contribution, I'll add the Chinese translation after the merge, or I can add it directly to your PR if that's ok with you, we plan to release this feature with v17 :)

It is worth noting that not only the component functions, but also the css class we need to be consistent with ant-design.

It is worth noting that not only the component functions, but also the css class we need to be consistent with ant-design.

Thank you for the reminder. I will ensure that both the component functions and the css class are consistent with ant-design in this component and the future components I contribute to.

Hello, guys!
Is this component already available in the release? I see it in the 'ng-zorro-antd/flex' package, but I don't find it in the documentation on the website.
