DataTable: column order via props breaks after drag & drop reorder

Describe the bug

When using DataTable with reorderableColumns, column ordering works correctly when controlled via props and when using drag & drop independently.
However, after performing a drag & drop reorder, updating the column order again via props (e.g. using a “shuffle” button) no longer works correctly.

The component appears to keep an internal column order state after drag & drop that is no longer synchronized with the column order provided via props.

Steps to reproduce the behavior

Steps to reproduce the behavior

Open the StackBlitz reproducer

Click the Shuffle Columns button
→ Columns reorder correctly

Drag & drop any column to change its order
→ Columns reorder correctly

Click the Shuffle Columns button again
→ Column order does not update correctly / remains stuck

Expected behavior

After using drag & drop to reorder columns, updating the column order via props (e.g. clicking the Shuffle button) should still reorder the columns according to the provided prop/state order.

The DataTable should remain fully controllable by external column state even after user interaction.

Start with the linked StackBlitz reproducer and inspect the DataTable behavior with reorderableColumns. Compare the external column-order prop before and after drag-and-drop, then verify that clicking Shuffle Columns reorders the columns according to the provided state after user interaction.
