Any display table in JMP can be turned into a data table. Interactively, you right mouse click on the table and select "Make into Data Table" or "Make into Combined Data Table".
To do this in a script, you pass a message of "Make into Data Table" to the object.
Here is the example from the Scripting Index
Help==>Scripting Index==>Make Into Data Table
Names Default To Here( 1 );
Open( "$SAMPLE_DATA/Baltic.jmp" );
p = PLS(
Y( :ls, :ha, :dt ),
X(
:v1,
:v2,
:v3,
:v4,
:v5,
:v6,
:v7,
:v8,
:v9,
:v10,
:v11,
:v12
)
);
pr = p << report;
pr[Outline Box( 2 )] << Close;
pr[Outline Box( 3 )] << Close;
tb = pr[Table Box( 1 )];
tb << Make Into Data Table;
