string or LLL reference
Contains the system name of the table. Is used for display in the backend.
For instance the "tt_content" table is of course named "tt_content" technically. However in the backend display it will be shown as "Page Content" when the backend language is English. When another language is chosen, like Danish, then the label "Sideindhold" is shown instead. This value is managed by the "title" value.
You can insert plain text values, but the preferred way is to enter a reference to a localized string. Refer to the Localization section for more details.
Example for table "sys_template":
'ctrl' => [ 'title' => 'LLL:EXT:frontend/Resources/Private/Language/locallang_tca.xlf:sys_template', ],
In the above example the
LLL: prefix tells the system to look up a
label from a localized file. The next prefix code:
EXT:frontend will look for
the data in the extension with the key "frontend". In that extension the
locallang_tca.xlf contains a XML structure inside of which one
label tag has an index attribute named "sys_template". This tag
contains the value to display in the default language. Other languages
are provided by the language packs.
