html table class change colums mod

[eluser]Ajaxboy[/eluser]
the current html table class doesn't allow to modify entire colums, just cells, here is a modification that allows you to modify entire colunms (i needed it html class wasn't flexible enough )

http://ellislab.com/codeigniter/user-gui...table.html

(please note that column change will take priority over a cell/row change...

(any hopes my changes can make it to a next release ? )

Code:

$tmpl = array ('table_open' => '<table id="tickets_list" class="tikets">',
  
                    'heading_row_start'   => '<tr>',
                    'heading_row_end'     => '</tr>',
                    'heading_cell_start'  => '<th>',
                    'heading_cell_end'    => '</th>',
     'col_1_start' => '<td>',
     'col_1_end' => '</td>',
     'col_2_start' => '<td>',
     'col_2_end' => '</td>',

                    'row_start'           => '<tr>',
                    'row_end'             => '</tr>',
                    'cell_start'          => '<td>',
                    'cell_end'            => '</td>',

                    'row_alt_start'       => '<tr>',
                    'row_alt_end'         => '</tr>',
                    'cell_alt_start'      => '<td>',
                    'cell_alt_end'        => '</td>'
  );

note that col_1_start, col_2_start are new, ( and you can add as many as there are columns ( col_3_start,col_4_start, etc)..

CI_Table class in system/libraries/Table.php function generate:
