Alter table structure.

You can add/edit/remove existing tables defined by hook_views_data().

This hook should be placed in MODULENAME.views_default.inc and it will be auto-loaded. MODULENAME.views_default.inc must be in the directory specified by the 'path' key returned by MODULENAME_views_api(), or the same directory as the .module file, if 'path' is unspecified.

After adding this hook to an existing module, you will need to clear the Drupal menu cache and the Views cache to have your default views be recognized.

Parameters

array $data: An array of all Views data, passed by reference. See hook_views_data() for structure.
