To make DataGrid2 more intuitive and efficient, I suggest the following three improvements:
・Column Reordering
Current: Only possible via MoveUp / MoveDown buttons, which is inefficient
Proposal: Enable drag-and-drop functionality to rearrange columns freely
・Column Copying
Current: No support for copying columns
Proposal: Allow Control+C / Control+V to copy and paste columns
・Accordion-style Row Display
Current: No expand/collapse functionality for rows
Proposal: Add an accordion-style feature to expand or collapse row details on demand
These features would significantly enhance data visibility and maintenance, benefiting all developers by enabling faster UI building and review.
