Close Data Table when Report Closes

Problem

You've opened a table to show a report. The table might be temporary or invisible, and you want the table to go away silently when the report is closed.

Solution

Use the <

// make a table
dt = New Table( "Temporary",
    Add Rows( 1e6 ),
    New Column( "x", Formula( Random Normal( 50, 30 ) ) ),
    New Column( "y", Formula( Random Normal( 50, 30 ) ) ),
    "Invisible"
);
// now make sure the formulas have finished evaluating
dt << RunFormulas;
// then clear the flag that says the table has changes that need to be saved
dt << SetDirty( 0 );
// finally, create a platform (or other window) with an OnClose script.
// the try() captures a message that might happen if the table is
// closed, causing the platform to close, causing the table to close...
dt << Bivariate( Y( :y ), X( :x ), <<ONCLOSE></ONCLOSE>

Platform with <<OnClose event attachedPlatform with <
