### SUMMARY Fixes conditional formatting painting empty cells when blank values (null, undefined, NaN, whitespace-only strings) are present. **Also in this PR:** - Introduced a reusable `isBlank` utility in `@apache-superset/core` that checks for null, undefined, NaN, and whitespace-only strings using lodash functions - Replaced local `isString`/`isBoolean` helper functions in `getColorFormatters.ts` with their lodash equivalents ### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF **Before:** Empty cells are incorrectly colored when conditional formatting rules like `metric < 50` are applied (null is coerced to 0, which satisfies the condition). <img width="1913" height="855" alt="Screenshot 2026-02-11 at 10 58 14" src="https://github.com/user-attachments/assets/0e6018a1-11fd-4423-ba29-efa1b94f164a"; /> **After:** Empty cells are left unformatted. Only cells with actual values are evaluated against conditional formatting rules. <img width="1911" height="864" alt="Screenshot 2026-02-11 at 11 11 20" src="https://github.com/user-attachments/assets/bb55502e-a90f-43d1-9db7-d470fe35da7a"; /> ### TESTING INSTRUCTIONS 1. Create a chart that supports conditional formatting (Pivot Table or Table) with a dataset that produces empty cells 2. Add a conditional formatting rule such as `metric < 50` 3. Verify that empty cells are **not** colored 4. Verify that cells with actual values below 50 **are** colored 5. Verify that `IsNull` conditional formatting still correctly highlights null cells 6. Verify that `IsTrue`/`IsFalse` conditional formatting still works on boolean columns ### ADDITIONAL INFORMATION <!--- Check any relevant boxes with "x" --> <!--- HINT: Include "Fixes #nnn" if you are fixing an existing issue --> - [ ] Has associated issue: - [ ] Required feature flags: - [ ] Changes UI - [ ] Includes DB Migration (follow approval process in [SIP-59](https://github.com/apache/superset/issues/13351)) - [ ] Migration is atomic, supports rollback & is backwards-compatible - [ ] Confirm DB migration upgrade and downgrade tested - [ ] Runtime estimates and downtime expectations provided - [ ] Introduces new feature or API - [ ] Removes existing feature or API -- This is an automated message from the Apache Git Service.
