React Tree List - Column Reordering

TreeList columns have the same order as fields in data objects. You can use the columns array to specify a different order. To reorder a column at runtime, change column.visibleIndex property.

Users can drag and drop column headers to reorder columns. To enable this feature, set the allowColumnReordering property to true. If you do not want users to drag a specific column, disable column.allowReordering property.

This demo shows how fixed columns behave during user-initiated reordering. Users can drag and drop columns within the following areas (but not between them):

Columns fixed to the left
Non-fixed columns
Columns fixed to the right

Sticky columns (fixed with the 'sticky' position) behave like non-fixed columns during reordering (even if they are in a state where they are attached to a border/fixed column). To see sticky columns in this demo, right-click a column to open a context menu. Choose "Set Fixed Position -> Sticky" to stick a column.
