ReorderableTable class

Reorderable (drag and drop) version of Table, a widget that displays its children in a two-dimensional grid.

The difference between table and list is that cells in a table are horizontally aligned, whereas in a list, each item can have children but they are not aligned with children in another item. Making a row draggable requires cells to be contained in a single widget. This isn't achievable with Table or GridView widget since their children are laid out as cells of widget instead of rows of widget.

Cells of each row must be children of ReorderableTableRow and each ReorderableTableRow must have a key.

See also:

  • ReorderableTableRow, which is the container of a row of cells.
  • Table, which uses the table layout algorithm for its children.
