Feature request

We should provide guidance how AG Grid can be localized.

• How to make app specific data (like column headers) localized
• How to handle dynamic language switching with AG Grid's behavior:

  The grid uses the locale as it is needed. It does not refresh as the locale changes. If your application allows changing the locale for the application, you must destroy and recreate the grid for it to use the new locale.

Use case

Applications do not forget to localize their AG Grid tables.
