This example shows how to create a table object that behaves like a list box. This table can include extra, hidden columns with additional information for the program. The size of the data in the table is limited only by the available system memory. It is also possible to allow direct editing of cells in this table.

 

Note that a table is not a direct substitute for a list box. There are some differences in behavior and the way responses are handled, so you may want to experiment with the behavior that is relevant for a particular application.
