To specify the data table in a display box, for example, in New Data Box(), use Set Data Table() and Get Data Table() to set and return a data table.
The following example uses the Big Class.jmp and Cities.jmp sample data tables. The sample data tables are opened invisibly. In a new window, a new data box is created containing Big Class.jmp. After waiting 1 second, the data box contents change to display cities.jmp.
dtC = Open( "$SAMPLE_DATA/Cities.jmp", "invisible" );
dtA = Open( "$SAMPLE_DATA/Big Class.jmp", "invisible" );
nw = New Window( "My Table", H List Box( dtBox = dtA << New Data Box() ) );
Wait( 1.0 );
dtBox << Set Data Table( Data Table( "Cities.jmp" ) );
