### SUMMARY This PR adds a **"Use gradient"** toggle to the table chart’s conditional formatting configuration. Previously, conditional formatting always rendered colors using a gradient (via varying opacity). With this change, users can explicitly choose between: - **Gradient mode** (current behavior): apply a color gradient by varying opacity based on the metric value. - **Solid mode** (new behavior): render all formatted cells using the selected color at full opacity. This gives users finer control over the visual styling of conditional formatting, especially in cases where gradients can be visually noisy or conflict with existing themes. Key changes: - Extend `ConditionalFormattingConfig` with a `useGradient` flag. - Update the color computation logic (`getColorFunction`) to respect `useGradient` and fall back to solid colors when disabled. - Add a **"Use gradient"** checkbox to the `FormattingPopoverContent` UI. - Default `useGradient` to `true` for backward compatibility with existing saved charts and dashboards. ### AFTER SCREENSHOTS <img width="3024" height="1964" alt="image" src="https://github.com/user-attachments/assets/4c07d4bd-652d-4e52-9209-f30bb8afb306"; /> <img width="3024" height="1964" alt="image" src="https://github.com/user-attachments/assets/cf8f3c93-3da6-4405-ae99-27b3e6ba73ea"; /> ### TESTING INSTRUCTIONS 1. **Basic UI behavior** 1. Create or open a **Table** chart. 2. Open the **Customize** / **Conditional formatting** panel. 3. Confirm that a **"Use gradient"** checkbox is visible in the formatting popover. 4. Ensure the checkbox is **checked by default** for: - Newly created conditional formatting rules. - Existing charts with conditional formatting. 2. **Gradient mode (backward compatibility)** 1. With **"Use gradient"** checked: - Apply a conditional formatting rule on a numeric column. - Verify that cell colors are rendered using varying opacity (gradient behavior). - Confirm that existing dashboards continue to look the same as before. 3. **Solid mode behavior** 1. Uncheck **"Use gradient"** for a conditional formatting rule. 2. Apply the rule and run the query. 3. Verify that formatted cells are rendered with **solid colors** (full opacity). 4. Toggle the checkbox on/off and confirm the visual changes update accordingly.
