# wpda_column_default

Filter **wpda_column_default** was added to influence the layout of list table columns. The filter works for all columns except the fist one. The first column holds the links to other actions.

```
function my_column_default(
	$value,
	$item,
	$column_name,
	$table_name,
	$schema_name,
	$wpda_list_columns,
	$list_number,
	$self
) {
	if ( '' !== $value ) {
		return $value;
	}

	if ( 'dutch' === $column_name ) {
		return 'NL-' . $item[ $column_name ];
	}
}
add_filter( 'wpda_column_default' , 'my_column_default' , 10 , 8 );
```

   You can use this filter in combination with action hook [wpda_after_list_table](/docs/wpda_after_list_table/) to add interactive elements to your list tables.
