Fix: Pagination for Grouped Rows

Issue:
Previously, pagination for grouped rows was inconsistent. The number of rows displayed per page varied because pagination was being calculated using the total number of child rows instead of the number of group header rows.

Fix:
Updated the pagination logic so that it correctly calculates the page size based only on the top-level (group header) rows. This ensures that each page displays a consistent number of grouped rows, regardless of how many child rows are expanded under each group.

Impact:

• Consistent pagination behavior for grouped rows.
• Users will now see the correct number of group rows per page.
• Child rows remain properly expandable without affecting pagination count.

Testing:

• Verified with multiple group configurations.
• Confirmed that the number of rows per page remains consistent even with groups expanded/collapsed.
