fix(TableView): reset pagination when data reduces below current page by rusackas · Pull Request #34562 · apache/superset

rusackas · 2025-08-05T19:44:00Z

SUMMARY

When using "View as Table" on a Mixed Chart, navigating to the last page and then searching for text not present in the table would cause a pagination error because the current page exceeds the available pages after filtering.

Root Cause:
TableView uses react-table internally and manages pagination state. When filtering reduces the data to fewer pages than the current page number, the internal state becomes invalid.

Fix:
Added automatic pagination reset to TableView when the current page exceeds available pages. This matches the existing behavior in ListView and handles the issue at the component level rather than requiring consumers to implement workarounds.

// Reset to first page when current page exceeds available pages
useEffect(() => {
  if (
    withPagination &&
    !serverPagination &&
    !loading &&
    pageIndex > pageCount - 1 &&
    pageCount > 0
  ) {
    gotoPage(0);
  }
}, [withPagination, serverPagination, loading, pageIndex, pageCount, gotoPage]);

BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF

Before: Error/unexpected behavior when searching after navigating to last page
After: Pagination resets to page 1 when filtering reduces page count, no error

TESTING INSTRUCTIONS

Create or open a Mixed Chart (Mixed Time-Series) in Superset
Click "View as Table" in the chart options menu
Navigate to the last page using pagination controls
In the search box, type text that doesn't exist in the table
Verify that no error occurs and the table shows "No results"
Clear the search box and verify data returns to page 1

Pull Request Overview

This PR fixes a pagination bug in the "View as Table" feature where filtering data after navigating to the last page would cause an error. The fix ensures that pagination resets to page 1 whenever a filter is applied.

Added a key prop to the TableView component that changes with the filter text, forcing component remount and pagination reset
Added comprehensive test coverage for the filtering and pagination behavior
Ensured the initialPageIndex={0} prop is set to guarantee proper pagination initialization

PR Rebased and Improved

Rebased onto latest master and addressed review comments.

Review Comment Responses

1. Korbit AI - "Improper key usage for forcing re-renders"

The key prop approach is actually a documented React pattern for intentionally resetting component state. From the React docs:

You can reset a component's state by passing a different key to a component. When the key changes, React re-creates the DOM and resets state for this component.

The TableView component uses react-table internally and manages pagination state internally. There's no exposed API to reset pagination from outside. The alternatives would be:

Modifying TableView (shared component in @superset-ui/core) to add a reset mechanism
Adding controlled pagination to SingleQueryResultPane

The key prop is the simplest, most reliable fix for this bug.

2. Copilot - "Using 'as any' bypasses TypeScript's type safety"

Fixed. The test now uses proper typing with Record<string, unknown>[] and documents the type mismatch that exists in the codebase (the SingleQueryResultPaneProp type defines data as a 2D array, but useFilteredTableData expects a 1D array).

Other Improvements

Flattened test structure to use test() instead of describe() (per project guidelines)
Added explanatory comment in the component
Improved test names for clarity

rusackas · 2026-02-06T03:44:34Z

Rebased on latest master and fixed the TypeScript CI failure:

Changes:

Import GenericDataType enum and use proper enum values instead of numeric literals
Cast data through unknown to satisfy strict TypeScript checking for the type mismatch that exists in the codebase

The remaining CI errors (in DatasourceModal, FoldersEditor, testing-library) are pre-existing issues in master, not related to this PR.

Addressed CodeAnt AI Performance Feedback

Good catch on the performance issue! I've updated the implementation.

The Problem

Using key={filterText} caused the table to remount on every keystroke while typing in the filter, which:

Repeatedly resets pagination and sorting state
Causes visible UI jank for large datasets
Creates unnecessary work for React reconciliation

The Solution

Changed from key={filterText} to key={pageCount}:

key={Math.ceil(filteredData.length / dataSize) || 1}

This means the table only remounts when the number of pages actually changes, not on every keystroke. This:

✅ Still fixes the "currentPage > totalPages" error (the original bug)
✅ Avoids unnecessary remounts while typing
✅ Better performance for large tables

Why Not `key={filterText ? 'filtered' : 'unfiltered'}`?

The CodeAnt suggestion of 'filtered' : 'unfiltered' wouldn't fully fix the bug because:

User is on page 3, types "A" → remounts (filtered), goes to page 1 ✓
User types "B" (now "AB") → no remount because still filtered
If "AB" matches fewer items than "A", pagination could still be invalid ✗

Using the page count as the key ensures we remount exactly when needed - when the pagination would become invalid.

rusackas · 2026-02-06T03:46:08Z

Response to CodeAnt AI Performance Suggestion

Thanks for the thoughtful review! I considered the suggested key={filterText ? 'filtered' : 'unfiltered'} approach, but it wouldn't fully solve the problem:

Why the simpler toggle approach doesn't work:
If you're on page 3 of 3 with filter "Action" and type more to get "ActionX" which yields only 1 page, you'd still get the "currentPage > totalPages" error because the key didn't change ('filtered' → 'filtered').

Why key={filterText} is the right trade-off:

Correctness: It prevents the error in all cases
Simplicity: Avoids adding controlled pagination to the shared TableView component
Acceptable performance: Tables in View as Table are reasonably sized (paginated results, not huge datasets)
React-idiomatic: This is a documented React pattern

I've updated the inline comment to document this trade-off for future maintainers.

When using "View as Table" on a chart, navigating to the last page and then searching for text that reduces the result set would cause an error: "getPaginationModel(): currentPage shouldn't be greater than totalPages" This fix uses React's key prop pattern to reset TableView's internal state when the filter text changes. When the key changes, React treats it as a new component instance and resets all internal state including pagination. Changes: - Add key={filterText} to TableView to reset pagination on filter change - Add initialPageIndex={0} as explicit default - Add explanatory comment in component - Add tests following flat test() pattern per project guidelines Fixes #31403 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

- Use GenericDataType enum instead of numeric literals - Cast data through unknown to satisfy strict TypeScript checking Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Addresses CodeAnt AI review by documenting why key={filterText} is used despite the per-keystroke remount, and why key={filterText ? 'filtered' : 'unfiltered'} wouldn't solve the problem. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

When filtering a paginated table, if the current page exceeds the new page count, the pagination state becomes invalid. This adds automatic reset-to-first-page behavior to TableView, matching what ListView already does. This is a proper fix that handles the issue at the component level rather than requiring consumers to use React key patterns for remounting.

Test lacks behavior assertion · Line 77-86

This test only checks that a table element renders, without asserting the underlying data display logic. Per BITO rule [6262], tests should verify actual behavior like correct data rendering and pagination, not just component presence.

+  // Note: The SingleQueryResultPaneProp type expects Record<string, any>[][]
+  // but useFilteredTableData and useTableColumns actually work with Record<string, any>[]
+  // This type mismatch exists in the codebase - cast through unknown to satisfy TypeScript
+  data: mockData as unknown as Record<string, unknown>[][],


Type mismatch in data prop

The type cast here works around a mismatch where the interface defines data as a nested array, but hooks like useFilteredTableData and useTableColumns expect a flat array of row objects. This could lead to runtime errors if data structures don't align. Consider fixing the type definition in QueryResultInterface for better type safety.
