Redundant columns

Would it be possible to contribute to this plugin? I’ve used it as a reference with the exception of the following method:

This removes the redundant columns keys, various places would need to be update, but it should give you an idea:


function get_column_keys(){
$data = $this->get_columns();
unset( $data['cb'] );
foreach( $data as $k => $v ){
$keys[] = $k;
}
return $keys;
}
