Describe the bug and the steps to reproduce it

Bug description:
When using the table with data fetching, the “Select All” checkbox behaves inconsistently across pages. You can see this behavior also in the docs examples.

In a table with all data loaded:

1. Select a few rows.
2. Change the page.
3. The “Select All” checkbox correctly shows the indeterminate state.

In a table with data fetched per page (table was given count of all rows):

1. Select a few rows.
2. Change the page.
3. The “Select All” checkbox state depends on the number of selected rows:

• If the number of selected rows is equal to or greater than pageSize, the checkbox appears empty (incorrect).
• If it’s less than pageSize, the checkbox shows the indeterminate state (correct).

Expected behavior:
In both scenarios, the “Select All” checkbox should correctly display the indeterminate state when some but not all rows in the dataset are selected, regardless of pagination or data fetching mode.

It seems that the checkbox state is calculated based on the currently displayed table data and pageSize, while it should be based on the total number of items and pageSize.

Thanks for your response.
