I have added a feature, in which we can display data in that column based on some condition. Best applicable where we want to enable certain action if data of row met some specific condition, say total price < 100.
for e.g.
// use single quote for condition, and $row will have all columns data, to use in condition
$col[“condition”] = ‘$row[“total”] < 100’;
NOTE: Custom button and conditional display is currently part of paid package.
