`nz-table` does not show pagination when `nzData` is an empty array

[DarrenDanielDay]

Reproduction link

https://stackblitz.com/edit/ng-zorro-antd-ivy-r8fnmf?file=src%2Fapp%2Fapp.component.ts

Steps to reproduce

Delete todo 4.

What is expected?

The pagination component should not be removed, and the pageIndex should be normalized to 1 automatically by the nz-pagination component. After the pageIndex changed to 1, it should display 3 records in page 1.

What is actually happening?

Then the nz-pagination component in nz-table is removed.

Is the current behavior expected? Relevant code stays unchanged for 3 years.

I think the current behavior is as expected. If you want to achieve the behavior you describe, you should use frontEnd pagination.

I think the current behavior is as expected. If you want to achieve the behavior you describe, you should use frontEnd pagination.

But in this example, we set nzTotal to 3, which implies data on other pages does exist. It's reasonable to show an empty table when nzData is an empty array but removing the nz-pagination component makes the user unable to switch to a different page. If this is expected, do you have any example or best practice for server pagination?

There should be a fallback logic on the server if the requested page is empty.

In your example, after id 4 is deleted and a request for pageIndex: 2 is sent, the server should return something like

{
    total: 3,
    pageIndex: 1,
    pageSize: 3,
    data: [1, 2, 3 ]
}

And you should use pageIndex from the server in the frontend after that.

Explicitly, I need this for server side pagination. When we have total but still nzDate:[] for any one pagination option then do not hide pagination setup.
