unMovable
The unMovable property prevents the user from moving a defined column of a table.
By default, a Table container allows the user to move the columns by dragging and dropping the
                column header. Use this property to prevent the user from changing the order of a
                specific column. Typically, unMovable is used on at least two
                columns to prevent the user from changing the order of the input on these
                columns.
For additional information, see the UNMOVABLE attribute topic in the Genero Business Development Language User Guide.
