Custom column selector for QDataTable

[ababo]

Since I need a custom toolbar for a data table I need to filter columns programmatically. How can I achieve that? Thanks.

I tried to do this using a computed value for Columns and pushing each column into an array of columns if the condition is met. But unfortunately the table does not update when a condition changes. I hope this will be possible in the new version. Or does anyone know another way to do this in the meantime?
