Pinning Columns (React)

The FlexGrid's allowPinning property allows users to pin columns to the left-hand side of the grid so they remain visible as the user scrolls the grid horizontally.

Setting allowPinning to SingleColumn allows users to toggle the pinned state of individual columns, changing their order if necessary.

Setting allowPinning to ColumnRange allows users to toggle the pinned state of column ranges, preserving the column order.
