Secondary Header

A secondary header is a body table row underneath the thead that can serve whatever purpose you need. It is passed the current rows of the table at the time so you can use it to tally numbers or show messages based on those rows.

Here is you how define a secondary header for a column:

1Column::make('Price')
2    ->sortable()
3    ->secondaryHeader(function($rows) {
4        return 'Subtotal: ' . $rows->sum('price');
5    }),

The secondary header row is enabled when ever any column calls secondaryHeader.

#Using a filter as a secondary header

You can use a filter as a header.

 1// Example filter
 2SelectFilter::make('Active')
 3    ->hiddenFromAll(), // Optional, hides the filter from the menus, pills, count.
 4 
 5// You can pass a filter directly
 6Column::make('Active')
 7    ->secondaryHeader($this->getFilterByKey('active')),
 8 
 9// Or use the shorthand method
10Column::make('Active')
11    ->secondaryHeaderFilter('active'), // Takes the key from the filter, which you can find in the query string when the filter is applied.
