Hiding a column

I have created a decision table and in action column, I am calling a java method. Once the column is added in action, I need to click the check box to call a Java method for further processing. But business user does not want the column to be displayed in decision table as it might be confusing for them. So there is any option to hide the column from decision table.

But the problem is whenever a new row is added, then user might not be able to click the check box which in turn we cannot call the java method for processing. Is there any way to tackle this issue? By default the checkbox is checked, then it might solve the issue. Attached screenshot.

Only when the check of Java method column is clicked "order1.getAllPharmacies( pharmacy ); " this line is getting added. Otherwise it will be added to then part.

Snippet:

            then
    pharmacy.setTempDeactivatedIndicator( "YES" );
    pharmacy.setReason( "Evacuation due to industrial spill or accident" );
    order1.getAllPharmacies( pharmacy );
