@Eric B thanks . can we change the background color of the 'Matched Bills' column in the above 2nd screenshot ? By modifying code

var matchedBillsSublist = scriptContext.form.addSublist({
                id : 'custpage_matched',
                type : ui.SublistType.INLINEEDITOR,
                label : 'Matched Bills',
                tab:'custpage_reports'
            });
