How to Get the List of Filtered data from nzTable

[Devharajan-Rangarajan]

What problem does this feature solve?

I am able to get the List of current page data from using the nzCurrentPageDataChange event. This is working fine after applying all the filters.

But I want to get all the filtered data not just the one's on the current page. Is there a way to do this?

Need this for exporting data to excel.

I tried printing the table itself and found that the nzTotal correctly shows the number of filtered items.

What does the proposed API look like?

This is clarification which is not available in the DOCS

Due to the limited information you provided, from your description I think you might be using front-end pagination based on the nz-table built-in logic, then you should be getting the full amount of data on the front-end, and nzTotal is calculated based on the length of the full amount of data.

Since you can get the full amount of data on the front end and can observe the filter changes, you can calculate the filtered data yourself.

Of course, you can get the filtered data via total$ in NzTableDataService, but this is an internal implementation of ng-zorro that may change in some version, so it's not recommended to rely on it directly for your scenario, and we won't be describing it in the docs.
