Hello
I Wand to Add more Colums in Expenses. (Attachments).
I edited in the File Purcheses.php for functional
________________________________________________________________________________________________________
$dakiemtra = '<div class="text-center"><div class="btn-group text-left">'
. '<button type="button" class="btn btn-default btn-xs btn-primary dropdown-toggle" '
. lang('dakiemtra') . ' <span class="caret"></span></button>
</div></div>';
$doanhnghiep = '<div class="text-center"><div class="btn-group text-left">'
. '<button type="button" class="btn btn-default btn-xs btn-primary dropdown-toggle" '
. lang('doanhnghiep') . ' <span class="caret"></span></button>
</div></div>';

$this->load->library('datatables');

$this->datatables
->select($this->db->dbprefix('expenses') . ".id as id, date,reference, {$this->db->dbprefix('expense_categories')}.name as category, amount, note, dakiemtra,doanhnghiep",false)
->from('expenses')
->join('expense_categories', 'expense_categories.id=expenses.category_id', 'left')
->group_by('expenses.id');
$this->datatables->add_column('Actions', $action, 'id');
$this->datatables->add_column('dakiemtra', $dakiemtra, 'dakiemtra');
$this->datatables->add_column('doanhnghiep', $doanhnghiep, 'doanhnghiep');

It's the Attachment colums, so it show the Link for download.
