Pull Request Overview

This PR fixes issues related to simple pivot prerequisites by resetting movedColumns on TABLE_CHANGED events, recalculating grid metrics based on updated state, and disabling advanced filters for non-filterable columns while also exposing the DisplayColumn type export.

• Updated context menu actions to disable advanced filtering on non-filterable columns.
• Added TABLE_CHANGED event listener in IrisGrid to reset movedColumns on table updates.
• Refactored state updates in Grid to batch changes and update metrics accordingly.

• The wildcard export may inadvertently expose internal members. Consider verifying that this export is intentional and does not lead to naming collisions or leaking implementation details.

export * from './IrisGridModel';

• [nitpick] Batching state updates and passing the updated state to updateMetrics is a good optimization; please double-check that the state used in updateMetrics accurately reflects all intended changes before the canvas is re-rendered.

this.setState(updatedState);
