Your library classes should be placed within your application/libraries folder,
Try this to load your library
Code:
$this->load->library('Table');
And call class method using this code
Here my_table must be in small case.
Code:
$this->table->add_row_id(0);
You Class name must be Capital and file name in small case
and both name must be same.
Have you set this in your application/config/config.php
$config['subclass_prefix'] = 'MY_';
