Summary by Sourcery

Fix table column drag-and-drop behavior after toggling column visibility by resetting drag listeners when columns are shown again.

Bug Fixes:

• Ensure draggable table columns reinitialize drag-and-drop handlers when a previously hidden column is made visible.
• Clear existing drag event handlers before re-binding them on table header cells to prevent inconsistent drag behavior.
