BaseTable visibility settings with disabled and hidden

[amivanoff]

The main principles of visibility settings

• show all confiured columns by default if not configured otherwise
• hide all non-confiured columns by default if not configured otherwise

Properties specification

• Add "disabled" property to the columns settings:

  • if this property is omitted from the columns settings, then:
    • if column exists in "order" or "column settings" then false (consider it enabled by default)
    • if column did exists in "order" or "column settings" then true (consider it disabled by default)
  • false -- see "hidden" property
  • true -- hide in the table, hide in the settings menu/dialog. Overrides "hidden" property

• Add "hidden" property to the columns settings:

  • if this property is omitted from the columns settings, then false (show all confiured by default)
  • false -- show column in the table, show in the settings menu/dialog as checked/selected
  • true -- hide column from the table, show in the settings menu/dialog as unchecked/unselected
