[TYPO3-dev] Backend Layouts and columns

[Stephen Bungert]

Hello,

I was looking at the new backend layout feature and see that you can enter a 
column name and column id number for each grid item... I tried googling for 
the answer to my question but haven't found an answer.

By default TYPO3 comes with 4 columns.

To get more you had to alter ext_tables.php file, like this for example:

  $TCA["tt_content"]["columns"]["colPos"]["config"]["items"] = array (
   "0" => array ("Normal||||||||||","0"),
   "1" => array ("Left||||||||||","1"),
   "2" => array ("Right||||||||||","2"),
   "3" => array ("Border||||||||||","3"),
   "4" => array ("Sidebar||||||||||","4"),
   "5" => array ("Top||||||||||","5"),
  );

Do I still have to do this first? If I want to use 6 columns with the 
backend layouts? Or can I just number the grid layouts however I want?
